CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This international application claims priority to U.S. Patent Application No. 62/641 ,928, filed on March 12, 2018, the disclosure of which is herein incorporated by reference in its entirety for all purposes.

BACKGROUND

[0002] It is possible for a fraudster to steal payment credentials when a user enters account information during a transactions. For example, card skimmers or cameras can be used to gain payment credentials or account information as a user enters the account information during a transaction (e.g., entering an account number on a keypad of an automated teller machine (ATM)). Current fraud prevention techniques to protect payment credentials or account information may be limited to further authentication techniques which still require a user to provide sensitive information which also may be obtained or stolen by fraudsters. In addition,

implementing additional authentication techniques may slow down the authentication and ultimately the authorization process such that interactions by users are reduced. Improved access systems are desired.

[0003] Embodiments of the invention address these and other problems, individually and collectively. BRIEF SUMMARY

[0004] Embodiments of the disclosure are directed method and systems for hands free interaction at a specific location. Through the user of a user device, a user may request and receive an access code to initiate a transaction at an access device in lieu of using a physical device such as a card to access a resource obtained through the access device. The access code may be transmitted to a user device via a particular communication channel and may be associated with an expiration time period, which limits the time period with which the code can be used to conduct a transaction at the access device, thereby increasing security. [0005] Some embodiments of the invention include a method including prompting, by an access device, a user to enter an access code; receiving, by the access device, the access code from the user; transmitting, by the access device, the access code to a validation computer, which validates the access code; receiving, by the access device, an access identifier or access token from the validation computer in response to validating the access code; transmitting, by the access device, an authorization request message including the access identifier or the access token to an authorizing computer; and receiving, by the access device, an authorization response message from the authorizing computer.

[0006] In some embodiments, the access device is an automated teller machine (ATM). In some embodiments, the method further includes, after receiving the access identifier or the access token: prompting, by the access device, the user for a personal identifier comprising a PIN. In some embodiments, the authorization request message includes the access identifier or the access token and the personal identifier. In some embodiments, the method further includes generating a notification indicating a result of authorization by the authorizing computer; and transmitting the notification to a user device associated with the user. In some embodiments, the notification includes an access code and a geographic location of the access device associated with the authorization. In some embodiments, the authorizing computer maintains information including an account number associated with the user, the type of transaction being conducted, a monetary amount of the transaction, and the personal identifier of the user.

[0007] Embodiments of the invention are further directed to an access device including a processor; a wireless communication device coupled to the processor; and a memory element including instructions that, when executed with the processor, cause the system to at least: prompt a user for an access code; receive the access code from the user; transmit the access code to a validation computer for validation; receive an access identifier or access token in response to validating the access code by the validation computer; transmit an authorization request message including the access identifier or the access token to an authorizing computer; and receive, from the authorizing computer, an authorization response message. The memory element can include code, executable with the processor, for implementing any of the methods described herein. [0008] Embodiments of the invention further include a computer-implemented method including receiving, by a validation computer and from a first user device, a request for an access code; determining, by the validation computer, the access code associated with an account number corresponding to the first user device; transmitting, by the validation computer, the access code to the first user device; receiving, by the validation computer and from an access device, the access code; validating, by the validation computer, the access code based at least in part on the access code associated with the request; generating, by the validation computer, a message that includes the account number associated with the access code in accordance with a determination that the access code is validated; and transmitting, by the validation computer, the message to the access device.

[0009] In some embodiments, determining the access code further includes determining an expiration time period associated with the access code. In some embodiments, the expiration time period is specified by a user associated with the first user device. In some embodiments, the expiration time period is transmitted with the access code to the first user device in response to the request for the access code. In some embodiments, the computer-implemented method further includes determining one or more geographic locations for access devices that are configured to utilize the access code.

[0010] In some embodiments, the computer-implemented method further includes updating a user interface of the first user device to display the one or more geographic locations for the access devices in response to the request for the access code. In some embodiments, determining the access code associated with the account number is in response to a user authenticating with the first user device prior to requesting the access code. In some embodiments, the validating computer maintains information that identifies a delivery channel preference for the access code.

[0011] In some embodiments, the validation computer and access device communicate by invoking an application programming interface (API) that uses mutual secure socket layer authentication and channel encryption. In some embodiments, the computer-implemented method further includes: receiving, by the validation computer, the access code from a second user device; validating, by the validation computer, the access code based at least in part on the access code associated with the request; generating, by the validation computer, a message that includes the account number associated with the access code in accordance with a determination that the access code is validating; and transmitting, by the validation computer, the message to the access device.

DETAILED DESCRIPTION

[0027] Embodiments of the invention are directed to systems and methods for improving upon conventional interaction systems. In some embodiments, a user may utilize a user device to request and receive an access code to be used at an access device, such as an ATM, to initiate any ATM transaction (e.g., deposit, withdrawal, transfer, etc.,) in lieu of using a physical card with payment credentials. In

embodiments, the access code may be a one-time use access code that is unique from other one-time use access codes. The access code may be associated with an expiration time period that is configurable by an entity such as an issuer or by the user themselves. The access code may be configured to work with an ATM only within the time window before the expiration time period expires. For example, a certain access code may be associated with a 30 minute expiration time period. A user who receives such an access code may only use the access code during the 30 minute time window at an ATM.

[0028] In accordance with at least one embodiment, upon the user interacting with an access device and providing the access code, the access device may communicate, via networks, with a validating server or computer for validating the received access code. If the access code is validated by the validating computer, the validating computer may identify payment account information associated with the requesting entity (e.g., user or user device) and transfer an access identifier or access token to the access device. The access device may request a personal identifier or PIN from the user upon receiving the access code, and the access identifier or the access token. In embodiments, the access device may communicate with an authorizing computer for authorizing the transaction initiated by the user at the access device (e.g., a withdrawal). The access device may generate and transmit the authorization request message that includes the access code, the access identifier or the access token, and other transaction information such as a type of transaction, an amount of the transaction, etc., to the authorizing computer for authorization of the transaction.

[0029] Embodiments of the invention provide several advantages. For example, in some embodiments a user does not have to enter any sensitive account information into any device including the access device during a transaction. In embodiments, the user can initiate and conduct a transaction with an access device without presenting or physically interacting with a card that includes relevant payment account information with the access device, as is conventionally required to conduct a transaction at an access device. Authentication and ultimately authorization processes are made more efficient by the embodiments of the invention as a transaction need not proceed to generate and transmit an authorization request message if an access code is not validated by a validation computer. In addition, with embodiments of the invention, fraudsters are unable to utilize electronic card skimmers or other skimming devices such as cameras to obtain or otherwise steal sensitive account information.

Embodiments of the present invention also provide for multiple authentication points ensuring more security during a transaction. For example, a user may be required to authenticate with an application of their user device to request the access code, provide the appropriate access code at the ATM, and provide a corresponding appropriate PIN to conduct the transaction at the access device. Additional advantages may be achieved by informing the user, via a graphical user interface of the user device, of locations of geographically close access devices that are configured to utilize the access code. Other advantages include the presentation of notifications of successful transactions utilizing the access code by the user or by other authorized users.

[0030] Prior to discussing the details of some embodiments of the present invention, description of some terms may be helpful in understanding the various embodiments.

[0031] An“access device” may be any suitable device that provides access to a system. An access device may also be used for communicating with a merchant computer, a transaction processing computer, an authentication computer, or any other suitable system. An access device may generally be located in any suitable location, such as at the location of a merchant. An access device may be in any suitable form. Some examples of access devices include POS or point of sale devices (e.g., POS terminals), cellular phones, PDAs, personal computers (PCs), tablet PCs, hand-held specialized readers, set-top boxes, electronic cash registers (ECRs), automated teller machines (ATMs), virtual cash registers (VCRs), kiosks, security systems, access systems, and the like. An access device may use any suitable contact or contactless mode of operation to send or receive data from, or associated with, a user mobile communication device. In some embodiments, where an access device may comprise a POS terminal, any suitable POS terminal may be used and may include a reader, a processor, and a computer-readable medium. A reader may include any suitable contact or contactless mode of operation. For example, exemplary card readers can include radio frequency (RF) antennas, optical scanners, bar code readers, or magnetic stripe readers to interact with a payment device and/or mobile communication device. The POS terminal may or may not initiate processing of transactions. In some embodiments, a access device may enable financial transactions without the need for a resource provider entity to be present. The access device may implement a secure cryptoprocessor for implementing cryptographic operations of sensitive information provided by and/or associated with a user. The access device may include a number of alarms, housing, tamper resistance mechanisms that prevent physical access. An access device may implement one or more authentication provisioning mechanisms, such as a key pad for entering a personal identification number, access code, or a biometric scanner for processing user provided biometrics (finger prints, iris, facial recognition, etc.).

[0032] A“digital wallet” can include an electronic device that allows an individual to conduct electronic commerce transactions. A digital wallet may store user profile information, payment credentials, bank account information, one or more digital wallet identifiers and/or the like and can be used in a variety of transactions, such as but not limited to eCommerce, social networks, money transfer/personal payments, mobile commerce, proximity payments, gaming, interacting with access devices, and/or the like for retail purchases, digital goods purchases, utility payments, purchasing games or gaming credits from gaming websites, transferring funds between users, and/or the like. [0033] An“access token” may include a substitute identifier for a real identifier to gain access to a resource. An example of an“access token” can be an“account token.”

[0034] An "account token" may include a substitute identifier for some

information. For example, a payment token may include an identifier for a payment account that is a substitute for an account identifier, such as a primary account number (PAN) or account number. For instance, an account token may include a series of alphanumeric characters that may be used as a substitute for an original account identifier. For example, an account token "4900 0000 0000 0001 " may be used in place of a PAN "4147 0900 0000 1234." In some embodiments, an account token may be "format preserving" and may have a numeric format that conforms to the account identifiers used in existing payment processing networks (e.g., ISO 8583 financial transaction message format). In some embodiments, an account token may be used in place of a PAN to initiate, authorize, settle or resolve a payment transaction. The account token may also be used to represent the original credential in other systems where the original credential would typically be provided. In some embodiments, an account token value may be generated such that the recovery of the original PAN or other account identifier from the token value may not be computationally derived.

Further, in some embodiments, the account token format may be configured to allow the entity receiving the account token to identify it as an account token and recognize the entity that issued the account token.

[0035] An“access code” may be a unique alpha-numeric string generated by a validation computer that is associated with a payment account or account information of a user. An access code may be valid for only a certain time period as indicated by the associated expiration time period.

[0036] An“expiration time period” may represent a range of time that an access code may be valid for use by a requesting user. In embodiments, the expiration time period can be specified by a user (by interacting with a user device or first user device) requesting the access code or by another entity such as an issuer or validation computer. The expiration time period can be for any suitable time range including seconds, minutes, or hours. For example, a given expiration time period could be thirty minutes or as little as one minute.

[0037] A“validation computer” may include one or more devices that can validate data. In some embodiments, it can process access code requests. An exemplary validation computer may include data processing subsystems, networks, and operations used to generate, maintain, and transmit access codes as well as payment account information to requesting entities. A validation computer may validate access codes in response to communications with user devices or access devices. A validation computer may be in communication with an authorizing computer. In embodiments, the validation computer may be configured for generating and transmitting notifications or messages to an access device or a user device regarding the status and/or user of an access code.

[0038] A“user” may include an individual. In some embodiments, a user may be associated with a first user device or a user device. The user may be associated with one or more accounts and/or personal accounts. The user may also be referred to as a cardholder, account holder, or consumer. A user may authorize another user (a second user) to utilize a second user device for providing an access code to an access device in accordance with embodiments described herein.

[0039] An“acquirer” may typically be a business entity (e.g., a commercial bank) that has a business relationship with a particular merchant or other entity. Some entities can perform both issuer and acquirer functions. Some embodiments may encompass such single entity issuer-acquirers. An acquirer may operate an acquirer computer, which can also be generically referred to as a“transport computer”.

[0040] An“authorization request message” may be a message that requests permission to conduct an interaction. For example, an authorization request message may include an electronic message that is sent to a payment processing network and/or an authorizing computer operated by an issuer of a payment card to request

authorization for a transaction. In embodiments, an authorizing computer may send an authorization request message to an issuer of a payment card to request authorization for a transaction. An authorization request message according to some embodiments may comply with (International Organization of Standardization) ISO 8583, which is a standard for systems that exchange electronic transaction information associated with a payment made by a consumer using a payment device or payment account. The authorization request message may include an issuer account identifier that may be associated with a payment device or payment account. An authorization request message may also comprise an access identifier or an access token, and/or additional data elements corresponding to“identification information” including, by way of example only: a service code, a CVV (card verification value), a dCW (dynamic card verification value), an expiration date, etc.. An authorization request message may also comprise “transaction information,” such as any information associated with a current transaction, such as the transaction amount, merchant identifier, merchant location, etc., as well as any other information that may be utilized in determining whether to identify and/or authorize a transaction.

[0041] An“authorization response message” may be an electronic message reply to an authorization request message. In some embodiments, it may be generated by an authorizing computer operated by an issuing financial institution or a payment processing network. The authorization response message may include, by way of example only, one or more of the following status indicators: Approval - transaction was approved; Decline - transaction was not approved; or Call Center - response pending more information, merchant must call the toll-free authorization phone number. The authorization response message may also include an authorization code, which may be a code that a credit card issuing bank returns in response to an authorization request message in an electronic message (either directly or through the payment processing network) to the merchant's access device (e.g. POS equipment) that indicates approval of the transaction. The code may serve as proof of authorization. As noted above, in some embodiments, a payment processing network may generate or forward the authorization response message to the merchant. In some embodiments, a payment network or issuer may generate or forward the authorization response message to an authorizing computer that indicates approval of a transaction or declining of a transaction.

[0042] An“authorizing entity” may be an entity that authorizes a request.

Examples of an authorizing entity may be an issuer, a governmental agency, a document repository, an access administrator, etc. An“authorizing computer” may be a computer operated by or associated with an authorizing entity and may be implemented by, for example, a server computer.

[0043] An“issuer” may typically refer to a business entity (e.g., a bank) that maintains an account for a user. An issuer may also issue payment credentials stored on communications devices.

[0044] A“resource provider” may be an entity that can provide a resource such as goods, services, information, and/or access. Examples of a resource provider include merchants. A“merchant” may typically be an entity that engages in transactions and can sell goods or services, or provide access to goods or services.

[0045] A“server computer” may include a powerful computer or cluster of computers. For example, the server computer can be a large mainframe, a

minicomputer cluster, or a group of servers functioning as a unit. In one example, the server computer may be a database server coupled to a Web server. The server computer may comprise one or more computational apparatuses and may use any of a variety of computing structures, arrangements, and compilations for servicing the requests from one or more client computers.

[0046] A“transaction processing computer” may include a computer that processes transaction. It may be in a network of one or more devices that can process and route transaction request messages. An exemplary transaction processing computer may include data processing subsystems, networks, and operations used to support and deliver authorization services, exception file services, transaction scoring services, and clearing and settlement services. A system that has a transaction processing computer may include VisaNet™. Transaction processing systems such as VisaNet™ are able to process credit card transactions, debit card transactions, and other types of commercial transactions. VisaNet™, in particular, may include a VIP system (Visa Integrated Payments system) which processes authorization requests and a Base II system which performs clearing and settlement services.

[0047] A“user device” may comprise a device that may be transported and operated by a user. A user device can be a“mobile communication device,” which may also provide remote communication capabilities to a network. Examples of remote communication capabilities include using a mobile phone (wireless) network, wireless data network ( e.g . 3G, 4G or similar networks), Wi-Fi, Bluetooth, Bluetooth Low Energy (BLE), Wi-Max, or any other communication medium that may provide access to a network such as the Internet or a private network. Examples of mobile communication devices include mobile phones (e.g. cellular phones), PDAs, tablet computers, net books, laptop computers, wearable devices (e.g., watches), vehicles such as

automobiles and motorcycles, personal music players, hand-held specialized readers, etc. A mobile communication device may comprise any suitable hardware and software for performing such functions, and may also include multiple devices or components (e.g. when a device has remote access to a network by tethering to another device - i.e. using the other device as a modem - both devices taken together may be considered a single mobile communication device). A mobile communication device may be configured to utilize an application for communicating with a validation computer, an access device, an authorizing computer, or other entities described herein for enabling the digital access code features described in embodiments herein. A mobile

communication device may be configured to run one or more software applications such as mobile applications or a digital wallet application.

[0048] An“application” may be computer code or other data stored on a computer readable medium (e.g., memory element or secure element) that may be executable by a processor to complete a task. An application may include a mobile application or a digital wallet. An application may be designed to streamline the process for accessing or otherwise interacting with an access device to conduct a transaction.

An application may allow the user to request an access code, select one or more access credentials, and conduct a transaction or request access to secure data at an access device without presenting a physical card (such as an identification or access card).

[0049] Details of some embodiments of the present invention will now be described. In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described. For example, memory elements, processors, and storage are present in the user device 102, access device 108, validation computer 106, transaction processing computer 1 10, and authorizing computer 1 12 but are not specifically illustrated for clarify of illustration.

[0050] FIG. 1 depicts a block diagram of a system and a process flow according to an embodiment of the invention. FIG. 1 illustrates at least some of the components for implementing embodiments of the invention. FIG. 1 includes a user 102, a user device 104, a validation computer 106, an access device 108, a transaction processing computer 1 10, and an authorizing computer 1 12. In embodiments, the access device 108 may include a processor and a wireless communications device for communicating with the user device 104 as well as the validation computer 106 and transaction processing computer 1 10. In embodiments, the access device 108, validation computer 106, and transaction processing computer 1 10 may communicate via available networks including the Internet via wireless or wired communication channels.

[0051] The user 102 may be associated with user device 104, which utilizes an application and/or a digital wallet that is further associated with one or more payment accounts or account information maintained by the authorizing computer 1 12. In embodiments, the application of the user device 104 may be configured to present, maintain, and update a user interface enabling the user 102 to request and receive an access code from the validation computer 106. In some embodiments, the user interface of the application of user device 104 may be configured to display geographic locations of one or more access devices (e.g., access device 108) for utilizing the access code for conducting a transaction without presenting a physical card. The user device 104 may be configured to utilize geo-location software and hardware for identifying a location of the user device as well as identifying distances between the user device and the locations of one or more access devices (such as access device 108) configured to utilize the access code.

[0052] The access device 108 may be any suitable device having wireless or wired communication capabilities and be capable of conducting any of the methods described herein. The access device 108 may comprise a processor and wireless or wired communication device. In embodiments, the access device 108 may be an automated teller machine (e.g., EMV enabled terminal, etc.,) that can enable financial transactions without the need for a human bank teller. The access device 108 may be configured to receive an access code from user 102 as well as a personal identifier or PIN from user 102. The access device 108 may be configured to generate and transmit a validation message to the validation computer 106 for validating the access code provided by user 102 as well as receiving the result of the validation from the validation computer 106. The access device 108 may be configured to receive an access identifier (e.g., a primary account number) or access token (e.g., payment token) from the validation computer 106. The access device 108 may be configured to generate and transmit an authorization request message from the access device 108 to the transaction processing computer 1 10 as well as receive an authorization response message from the transaction processing computer 1 10 for conducting a transaction with the user 102. The access device 108 may include hardware that carries out instructions embodied as code in a computer-readable medium (e.g., non-transitory computer-readable medium). An exemplary processor may be a central processing unit (CPU). As used herein, a processor can include a single-core processor, a plurality of single-core processors, a multi-core processor, a plurality of multi-core processors, or any other suitable combination of hardware configured to perform arithmetical, logical, and/or input/output operations of a computing device.

[0053] The transaction processing computer 1 10 may be configured to receive messages, data objects, or packets from the access device 108 that include the personal identifier (PIN), access code, and access identifier or access token for authorizing a transaction conducted by the user 102 at the access device 108

(authorization request message). The transaction processing computer 1 10 may be configured to maintain and transfer a result of an authorization process using an authorization request message (i.e. , the authorization response message) to the validation computer 106 as well as information about the transaction such as the account number associated with the transaction, the type of transaction (e.g., withdrawal, deposit, transfer, etc.), a monetary amount of the transaction, and a personal identifier of the user. The transaction processing computer 1 10 may communicate with an authorizing computer 1 12 for authorizing the transaction conducted by the user 102 at the access device 108 such as by transmitting or otherwise providing the authorization request message to the authorizing computer 1 12 and receiving the authorization response message from the authorizing computer 1 12.

[0054] In embodiments, if the authorization response message indicates that the transaction is authorized, the transaction processing computer 1 10 may transmit the authorization response message to the access device 108 where the user 102 can conduct the intended transaction.

[0055] A method according to the embodiments of the invention can be described with respect to FIG. 1 . FIG. 1 shows a process flow of a method for conducting digital access code features as described herein.

[0056] Additional methods and processes may be included within these methods and may be recognized by one of ordinary skill in the art, in light of the description below. Further, in some embodiments of the present invention, the described methods may be combined, mixed, and matched, as one of ordinary skill would recognize. [0057] One embodiment of the invention is directed to a method. The method comprises: prompting, by an access device (e.g., an ATM machine), a user to enter an access code; receiving, by the access device, the access code from the user;

transmitting, by the access device, the access code to a validation computer, which validates the access code; receiving, by the access device, an access identifier (e.g., a primary account number) or access token (e.g., a payment token) from the validation computer in response to validating the access code; transmitting, by the access device, an authorization request message including the access identifier or the access token to an authorizing computer (e.g., an issuer computer); and receiving, by the access device, an authorization response message from the authorizing computer. FIG. 1 shows a method according to the embodiment of the invention.

[0058] At step 1 , user 102 may interact with user device 104 to request an access code from validation computer 106. In embodiments, the user device 104 may be configured to utilize an application and/or a digital wallet which presents a user interface enabling the user 102 to request the access code. In accordance with at least one embodiment, the user 102 may be required to authenticate with the user device 104 and/or application to request the access code from the validation computer 106. For example, the user 102 may provide a password, an answer to a security question, or utilize a biometric input to authenticate themselves with the application, user device 104, or validation computer 106 for requesting the access code. In some embodiments, the request for the access code may include the authentication data provided by the user 102 to the user device 104 or application of the user device 104 used to authenticate the user 102. In some embodiments, the request for the access code may include an identifier of the user 102 or of the user device 104 such that the validation computer 106 can determine an appropriate payment account to generate an access code corresponding to the request. In some embodiments, the request for the access code can include information from an application of the user device 104, such as login information provided by user 102, such that the validation computer 106 can identify the user and generate the appropriate access code that corresponds to their payment account and can be validated upon being received by an access device 108 as described herein.

[0059] At step 2, the validation computer 106 may identify an account number or payment account number associated with the user 102 and/or user device 104 to generate or otherwise obtain an access code. The validation computer 106 may obtain or generate an expiration time period for the access code requested by the user 102. In embodiments, the expiration time period may be of a certain length as specified by the user 102 at some previous point, by the validation computer 106 or authorizing computer 1 12 according to policies. For example, a given policy may determine certain expiration time periods based on the number of access code requests the user 102 has requested in a given time period (day, week, month), based on a location of the user device 104, or based on a threshold period such as not to exceed thirty minutes. In embodiments, the expiration time period can be specified by the user interacting with the user device 104 (first user device) that presents or is configured to utilize an application or user interface for specifying the expiration time period to associate with an access code or a request for an access code. In cases where the user 102 has successfully authenticated themselves with the user device 104 and/or validation computer 106, the validation computer 106 provides the access code and expiration time period to the user device 104 for display or presentation to the user 102.

[0060] At step 3, the user 102 may interact with the access device 108 by providing the access code received at step 2 from the validation computer 106. In embodiments, the access device 108 may prompt the user 102 to provide or otherwise enter the access code. It should be noted that the digital access code features described herein may include a different user (not user 102) utilizing the access code provided at step 2 to conduct a transaction on behalf of user 102 or with the authority of user 102. In such cases the different user must still know or otherwise request the PIN and access code from the user 102. In embodiments, the digital access features described herein may include a shared application or mobile application among trusted devices that enables a requested access code from one party to be shared or otherwise transmitted to another user device of another party.

[0061] At step 4, the access device 108 may transmit the access code provided by the user 102 to the validation computer 106 for validation. In embodiments, the validation computer 106 may validate the access code by determining whether the access code received from the access device 108 matches the access code provided to the user device 104. Validation of the access code by the validation computer 106 may include utilizing other factors such as identifying the status of the access code since it was provided to the user device or the status of the associated payment account. For example, the user 102 may have interacted with user device 104 which in turn communicated with the validation computer 106 to cancel the access code, and/or delete or suspend a payment account or corresponding payment card.

[0062] At step 5, if the access code is validated by the validation computer 106, the validation computer 106 may transmit a data object or data message to the access device 108 that includes a response code indicating the status of the validation

(successful or not successful), the access identifier (e.g., a primary account number) or an access token (e.g., a payment token) if the validation was successful, and the access code. If validation is not successful the access device 108 will only be informed that the access code is not validated and no access identifier or access token is transmitted to the access device 108.

[0063] At step 6, if the validation was successful, the access device 108 prompts the user 102 to provide a personal identifier or PIN for conducting the transaction. The access device 108 generates an authorization request message that includes the PIN, the access identifier or the access token as well as transaction details or information (transaction type, account type, amount of transaction (if applicable) etc.). The access device 108 transmits the authorization request message along with a transaction time and date to the transaction processing computer 1 10 for authorizing the transaction. In embodiments, the transaction processing computer 1 10 is configured to resolve the access token received from the access device 108 to determine a primary account number such as by performing a mapping of data included in the access token to determine the primary account number or decrypting data included in the payment token or the payment token itself to determine the primary account number.

[0064] At steps 7 and 8 the transaction processing computer 1 10 and authorizing computer 1 12 authorizes or declines the transaction utilizing the authorization request message from the access device 108. The authorizing computer 1 12 generates an authorization response message which is transmitted to the transaction processing computer 1 10 which indicates that the transaction being conducted by user 102 is authorized or declined. At the end of the day or at any other suitable period of time, a clearing and settlement process may occur between the transaction processing computer 1 10 and authorizing computer 1 12.

[0065] At step 9, the transaction processing computer 1 10 transmits the authorization response message to the access device 108 which enables the user 102 to conduct the transaction (if authorized) or not conduct the transaction (if declined) as indicated by the authorization response message.

[0066] At step 10, the transaction processing computer 1 10 communicates the result of the authorization (authorization response message) to the validation computer 106. In embodiments, the validation computer 106 maintains a status of access codes, usage of access codes, and results of transactions conducted utilizing the access codes.

[0067] At step 1 1 , the validation computer 106 generates and transmits a notification or message to the user device 104 indicating whether a transaction was successfully conducted or not successfully conducted using the access code and as well as what time and date the transaction was conducted.

The process 1400 may include transmitting, by the validation computer, the access code to the first user device at 1406. In embodiments, the validation computer may maintain information which indicates a preference for a certain communication channel to provide the access code to the first user device. For example, the validation computer may provide the access code to the first user device via a push notification of an application of the first user device, via a short message service (SMS) text message, via email, or via a phone call.

[0103] The process 1400 may include receiving, by the validation computer and from an access device, the access code at 1408. The process 1400 may include validating, by the validation computer, the access code based at least in part on the access code associated with the request at 1410. In embodiments, validation of the access code may include determining that the access code that was previously provided to the first user device matches the access code received at 1408, determining that the access code is not being used outside of the associated expiration time period, and/or that some other account activity has not occurred which suspends the access code or associated payment account. In some embodiments, the access code may be received by the access device from a second user device. In embodiments, the user (first user) associated with the first user device may transmit, provide, or otherwise authorize another user (a second user) associated with a second user device to utilize the access code to conduct a transaction at the access device on their behalf or with their authority. In such cases, the user (first user) may receive notifications from the validation computer indicating when the access code was utilized and the result of the transaction (e.g., the validation of the access code was successful, a transaction was successfully conducted, etc.). The process 1400 may include generating, by the validation computer, a message that includes the account number associated with the access code in accordance with a determination that the access code is validated at 1412. The process 1400 may conclude at 1414 by transmitting, by the validation computer, the message to the access device.
