TRACKING

FIELD

[0001]The present disclosure relates to the sharing and aggregation of transaction data, specifically the aggregation of transaction data on a mobile computing device received via transmission from an integrated circuit payment card used to conduct the payment transaction.

BACKGROUND

[0002] For many years, a number of consumers have kept track of their payment transactions. Consumers have used ledgers, registers, books, and, more recently, spreadsheets and computer applications for keeping track of payment transactions, such as to manage personal budgets and to detect fraud. In more recent times, application programs often rely on communications with issuing banks in order to obtain account and transaction information for consumers, many times by using login information for the issuing bank's website as provided by the consumer.

[0003] However, such methods often require a consumer to first sign up with their issuing bank, sign up with the application's service, provide their private login credentials for their issuing bank to the service, and verify access of the application service to their account with the issuing bank. Such a process can be time consuming and very cumbersome for consumers, which may discourage consumers from joining, and may also discourage consumers for security reasons due to the requirement to divulge their personal login information. Further, such account and transaction history provided by such services is often done at periodic intervals or when prompted by the consumer, and thus may not provide data in real time, which may result in increased risk of fraud.

[0004] Thus, there is a need for a technical solution to provide for tracking of consumer transactions in real time that requires a minimal amount of consumer interaction and maintains consumer privacy and security. SUMMARY

[0005] The present disclosure provides a description of systems and methods for the sharing and aggregation of transaction data using an integrated circuit payment card.

System for Sharing and Aggregating Transaction Data

[0024] FIG. 1 illustrates a system 00 for the sharing and aggregation of transaction data via the use of an integrated circuit payment card.

[0025] The system 100 may include an integrated circuit payment card 102. The integrated circuit payment card 102, as discussed in more detail below, may store payment details associated with a payment account held by a consumer. The integrated circuit payment card 102 may be inserted into a point of sale device 104 during the conducting of a payment transaction for the purchase of goods or services. The point of sale device 104 may read the payment details stored in the integrated circuit payment card 102 using methods and systems that will be apparent to persons having skill in the relevant art.

[0026] Once the payment details have been read and the transaction is ready to be processed, the point of sale device 104 may transmit transaction details for the payment transaction to a payment network 106 for processing. The transaction details may be included in an authorization request, which may be generated by the point of sale device 104 or another system, such as a computing system of an acquiring bank associated with a merchant operating the point of sale device 104. The payment network 106 may process the payment transaction using methods and systems that will be apparent to persons having skill in the relevant art.

[0027] The payment network 106 may include one or more processing servers 108. The processing server 108 may be configured to process the payment transaction using suitable methods and generate and transmit an authorization response to the point of sale device 104 indicating approval or denial of the payment transaction. In some instances, the processing server 108 may store transaction data for the payment transaction, such as in a local transaction database.

[0028] The point of sale device 104 may receive the authorization response that indicates approval or denial of the payment transaction. An employee and consumer involved in the payment transaction may view the authorization response or an indication thereof via the point of sale device 104, and may finalize the transaction.

[0029] The integrated circuit payment card 102 may include an antenna embedded in the payment card. In some embodiments, the antenna may be a passive antenna that operates using electric power provided by the point of sale device 104. The integrated circuit payment card 102 may receive data indicating that the

authorization response has been received by the point of sale device 104, and then may transmit a message to a nearby mobile computing device 1 10 using the embedded antenna.

[0030] The mobile computing device 1 10 may be associated with a consumer that is also associated with the integrated circuit payment card 102. The mobile computing device 1 10 may receive the message from the integrated circuit payment card 102, which may include transaction data and any other suitable data associated with the payment transaction. In some instances, the data included in the message may be based on the content of the authorization response. For example, if the

authorization response indicates approval of the payment transaction, the data may include transaction data, such as the transaction amount, transaction time and/or date, merchant name, etc. In some cases, the included data may be set by the consumer. In another example, if the authorization response indicates denial of the payment transaction, the message may include data indicating a reason for the denial, such as an incorrect personal identification number was provided, there were insufficient funds in the account, etc.

[0031]The mobile computing device 1 10, discussed in more detail below, may receive the message and/or transaction data and may store the transaction data locally in the device. The consumer may then use the mobile computing device 1 10 to view the transaction data for the payment transaction and for other payment transactions conducted using the integrated circuit payment card 102 whose data was provided to the mobile computing device 1 10 by the integrated circuit payment card 102. In some embodiments, the mobile computing device 1 10 may also receive transaction data for additional payment transactions associated with the consumer, such as via other payment accounts and/or other integrated circuit payment cards 102. In such an embodiment, the mobile computing device 1 0 may aggregate all of the transaction data for view by the user, using methods and systems that will be apparent to persons having skill in the relevant art.

[0032] In some embodiments, the integrated circuit payment card 102 may encrypt the transaction data prior to transmission to the mobile computing device 1 10 using known or new encryption techniques. The mobile computing device 10 may receive the encrypted data, and may decrypt the data using methods and systems that will be apparent to persons having skill in the relevant art. In such an

embodiment, the transaction data transmitted to the mobile computing device 1 10 may be more secure, as any additional devices that may pick up the transmission may be unable to decrypt, and thereby analyze, the data.

[0033] The use of the integrated circuit payment card 102 to share transaction data for aggregation on the mobile computing device 1 10 may provide a number of advantages over existing systems. As the integrated circuit payment card 102 is inserted in the point of sale device 104 used to conduct the payment transaction, the integrated circuit payment card 102 may receive the transaction data for the payment transaction prior to any other system or device. As a result, the integrated circuit payment card 102 may be able to provide the transaction data to the mobile computing device 1 10 in real-time, and much faster than using traditional systems.

[0034] In addition, such a system for aggregating transaction data may be more convenient for consumers. As the transaction data may be provided directly from the point of sale device 104 to the mobile computing device 1 10 by the integrated circuit payment card 102, the consumer may obtain a record of payment transactions without the need to use third party services, provide secure login information, or retrieve the transactions from a plurality of different issuers, websites, or application programs. As a result, the system 100 may be more convenient, and thus more accommodating, to consumers than traditional systems used for aggregating transaction data. Integrated Circuit Payment Card

Process for Sharing and Aggregating Transaction Data

[0048] FIG. 4 illustrates a process for the sharing and aggregation of transaction data using the system 100 of FIG. 1 , which may be part of a larger authentication, authorization and/or approval process.

[0049] In step 402, the integrated circuit payment card 102 may be inserted into the point of sale device 104. As part of the insertion, the integrated circuit payment card 102 and point of sale device 104 may initiate communications, such as using the contact interface 204 of the integrated circuit 202 of the integrated circuit payment card 102. In step 404, the point of sale device 104 may read data stored in the memory 212 of the integrated circuit payment card 102, such as the payment details for the payment transaction being conducted.

[0050] In step 406, the point of sale device 104 may process the payment transaction using methods and systems that will be apparent to persons having skill in the relevant art. As part of the processing of the payment transaction, in step 408 the point of sale device 104 may receive an authorization response from the payment network 106. The authorization response may include at least an indication of the approval or denial of the payment transaction. [0051] In step 410, the integrated circuit payment card 102 may detect the receipt of the authorization response by the point of sale device 104. In some embodiments, the detection may be via the receipt of the authorization response or indication thereof by the receiver 208 of the integrated circuit 202 of the integrated circuit payment card 102 from the point of sale device 104. In some instances, the indication may include the transaction data. In other instances, the transmitter 210 may request transaction data from the point of sale device 104, which may be received by the receiver 208 and stored in the memory 212.

[0052] In step 412, the processor 206 of the integrated circuit 202 of the integrated circuit payment card 102 may generate a transaction message, which may include the transaction data, the indication of approval or denial of the payment transaction, and/or any other suitable data. In step 414, the processor 206 may encrypt the transaction message using one or more methods of encryption. In step 416, the transmitter 210 of the integrated circuit payment card 102 may transmit the encrypted transaction message to the mobile computing device 1 10 using the antenna 214 powered by electric power from the point of sale device 104.

[0053] In step 418, the receiving unit 302 of the mobile computing device 1 10 may detect (e.g., receive) the encrypted message from the integrated circuit payment card 102. In step 420, the processing unit 304 of the mobile computing device 1 10 may decrypt the transaction message to obtain the data included therein. In step 422, the mobile computing device 1 10 may store the received transaction data as a transaction data entry 310 in the transaction database 308 and make the data available for viewing by the user via the display unit 312. In embodiments where the transaction message may include a message for display rather than transaction data, such as a message indicating a reason for denial of the payment transaction, the message may be displayed by the display unit 312 without storage in the transaction database 308 and/or memory 316.

Process for Sharing Transaction Data

[0054] FIG. 5 illustrates a process 500 for the real time sharing of transaction data by the integrated circuit payment card 102.

[0055] In step 502, the integrated circuit payment card 102 may be inserted into the point of sale device 104 and communication established between the point of sale device 104 and the integrated circuit payment card 102 via the contact interface 204 of the integrated circuit 202. In step 504, the receiver 208 of the integrated circuit 202 may receive a request for payment data from the point of sale device 104. The processor 206 of the integrated circuit 202 may identify the requested payment data in the memory 212, which may be transmitted by the transmitter 210 to the point of sale device 104, in step 506.

[0056] In step 508, the receiver 208 may receive an authorization response or indication thereof from the point of sale device 104 for the payment transaction for which the payment details were requested. In some embodiments, the authorization response may include transaction data for the payment transaction. In a further embodiment, the transaction data may only be included if the authorization response indicates approval of the payment transaction.

[0057] In step 510, the processor 206 of the integrated circuit 202 may determine if the transaction was approved based on data included in the authorization response or indication thereof. If the transaction was approved, then, in step 512, the processor 206 may generate an approval message. The approval message may include at least an indication that the payment transaction was approved, and transaction data for storage in the mobile computing device 110 and display to a user. In some instances, generating the approval message may include requesting transaction details from the point of sale device 104 and receipt thereof for inclusion in the message.

[0058] In step 514, the processor 206 may encrypt the generated transaction message. In step 516, the transmitter 210 of the integrated circuit 202 of the integrated circuit payment card 102 may transmit the encrypted message to the mobile computing device 1 10.

[0059] If, in step 510, the processor 206 determines that the payment transaction was denied, then, in step 518, the processor 206 may generate a denial message. The denial message may include an indication that the payment transaction was denied, and may further include a reasoning or explanation, such as provided in the authorization response or indication thereof forwarded by the point of sale device 104. For example, the denial message may include a message that the transaction was denied due to a lack of available funds. The process may then proceed to step 514, where the denial message may be encrypted, and then to step 516, where the encrypted message may be transmitted to the mobile computing device 1 10. Process for Aggregating Transaction Data

[0060] FIG. 6 illustrates a process 600 for the real time aggregation of transaction data in the mobile computing device 110 as provided by the integrated circuit payment card 102.

[0061] In step 602, the receiving unit 302 of the mobile computing device 1 10 may monitor for transaction messages being emitted by the integrated circuit payment card 102. In some embodiments, step 602 may be initiated by a user of the mobile computing device 1 10, such as, for instance, by the execution of an application program stored in the mobile computing device 1 10. In step 604, the processing unit 304 of the mobile computing device 10 may evaluate to see if any transaction messages have been received by the receiving unit 302. If no messages have been received, then the process may return to step 602 where monitoring for messages may continue.

[0062] Once a message has been received, then, in step 606, the processing unit 304 may identify encrypted data included in the received transaction message. In step 608, the processing unit 304 may decrypt the encrypted data to obtain transaction data included therein, such as by using a decryption key and/or algorithm stored in the memory 316 of the mobile computing device 1 10. In step 610, the processing unit 304 may generate a transaction data entry 310 including the transaction data and store the generated entry in the transaction database 308 of the mobile computing device 1 10.

[0063] In step 612, the processing unit 304 may determine if additional transaction data regarding the payment transaction is required. If additional data is required, then, in step 614, the transmitting unit 306 may transmit a request for supplemental transaction data. In some embodiments, the request may be transmitted to the processing server 108 of the payment network 106. In other embodiments, the request may be transmitted to the integrated circuit payment card 102. In some instances, the request may specify the additional transaction data being requested, such as based on input received from the input unit 314 from the user.

[0064] In step 616, the receiving unit 302 may receive the requested supplemental transaction data as a response to the transmitted request. Once the supplemental data has been received, or if no additional data was required at step 612, then, in step 618, the display unit 312 of the mobile computing device 1 10 may display the transaction data for the payment transaction to the user.

Exemplary Method for Sharing Transaction Data

[0065] FIG. 7 illustrates a method 700 for the sharing of transaction data in real time to a mobile computing device from an integrated circuit payment card.

[0066] In step 702, a removable integrated circuit payment card (e.g., the integrated circuit payment card 102) may be stored inside a point of sale device (e.g., the point of sale device 104), wherein the integrated circuit payment card 102 is configured to store payment credentials associated with a payment account and includes an antenna (e.g., the antenna 214) configured to operate using electric power provided by the point of sale device 104. In one embodiment, the antenna 214 may be a radio frequency antenna.

[0067] In step 704, a receiver (e.g., the receiver 208) of the integrated circuit payment card 02 may receive transaction data for a payment transaction. In some embodiments, the transaction data may include at least one of: transaction amount, transaction time and/or date, merchant name, merchant category, merchant industry, product data, and user-supplied data.

[0068] In step 706, the received transaction data may be encrypted by a processor (e.g., the processor 206) of the integrated circuit payment card 102. In some embodiments, the removable integrated circuit payment card 102 may include an integrated circuit (e.g., the integrated circuit 202) including at least the receiver 208 and the processor 206.

[0069] In step 708, an indication of receipt of an authorization response associated with the payment transaction may be received by the receiver 208 of the integrated circuit payment card 102. In some embodiments, the transaction data for the payment transaction may be received after the indication of receipt of an

authorization response. In step 710, the antenna 214 may transmit the encrypted transaction data to a mobile communication device (e.g., the mobile computing device 1 10).

Exemplary Method for Aggregating Transaction Data

[0070] FIG. 8 illustrates a method 800 for the aggregation of transaction data in real time on a mobile computing device as received from an integrated circuit payment card. [0071] In step 802, transaction data for a plurality of payment transactions may be stored in a memory (e.g., the transaction database 308). In some embodiments, the plurality of payment transactions may be associated with more than one payment account.

[0072] In step 804, encrypted transaction data for a new payment transaction may be received by a receiving device (e.g., the receiving unit 302) from a passive antenna (e.g., the antenna 214) of a removable integrated circuit payment card (e.g., the integrated circuit payment card 102). In one embodiment, the antenna 214 may be a radio frequency antenna. In some embodiments, the transaction data may include at least one of: transaction amount, transaction time and/or date, merchant name, merchant category, merchant industry, product data, and user-supplied data. In one embodiment, the antenna 214 of the removable integrated circuit payment card 102 may be powered by a point of sale device (e.g., the point of sale device 104) storing the removable integrated circuit payment card 102.

[0073] In step 806, the received encrypted transaction data may be decrypted by a processing device (e.g., the processing unit 304) to obtain unencrypted transaction data. In step 808, the unencrypted transaction data may be stored in the memory. In step 810, the stored transaction data for the plurality of payment transactions and the stored unencrypted transaction data for the new payment transaction may be displayed by a display device (e.g., the display unit 312).
