PAYMENT SLIP

FIELD OF DISCLOSURE

[0001] The present disclosure relates to cardless payment transactions, and in particular, to system and method for real-time generation of payment slips for performing cardless transaction.

BACKGROUND OF THE DISCLOSURE

[0002] In recent years, financial services industry has become increasingly expanded. Banks, for example, now offer a wide variety of products and services not previously available to customer. With limited cash in hand and an indefinite crunch in sight, most people are switching to cashless transactions. There are many popular ways for cashless transaction such as net banking, mobile wallet. After the success of mobile wallet and other ways of cashless transaction financial services industry focusing on point of sale (POS) system. Nowadays, financial industries are offering POS system which is combination of hardware and software. POS system includes basically software and POS machine wherein, the POS machine is a terminal, that allows a merchant (hereinafter referred as trader, dealer, wholesaler, mercantile) to accept payments by means of cards from his customers. It works a bit like an ATM machine except that, the machine is designed to only accept payments on behalf of the merchant.

[0003] POS system (hereinafter referred as POS terminal) is alternative option to merchants so that they may find a more convenient means to receive payments from their clients. Today, a retail industry such as supermarkets, grocery shop or big retailer shop or shopping mall is one of the predominant users of POS terminals. Conventionally at the POS, the merchant (hereinafter referred as cashier, treasurer, and clerk) would calculate the amount payable by the customer and indicate the amount, and indicate the options for the customer to make payment. The customer inserts credit card/debit card in the card slot and secretly enters his/her pin and confirm by pressing enter. After receiving payment, the merchant may issue a receipt for the transaction, which is usually printed. However, the process of engaging in cash/cashless transaction at a shopping mall/retail shop, (which may include waiting in line for bill, bill receipt, cash transaction, interacting with the cashier, performing transaction after insertion of card and OTP etc.) is increasingly viewed by financial institution customers as burdensome, time-consuming, and inefficient.

[0004] Irrespective of these drawbacks, additionally, it is often cumbersome to carry debit/credit cards and keeping such cards safe and also recalling/remembering passwords cause inconvenience in use and raise transaction security issues. However, most people carry smartphones or communication device. While smartphones have received a great deal of attention, many users still have older cell phones that do not run Android or Apple software. The high cost of smartphones limits their acceptance in cost-sensitive foreign markets and among cost-sensitive customers. The fragmented mobile phone market limits the success of mobile payment systems that function with only a particular kind of smartphone, or that do not work with older legacy cell phones. Therefore, the inventor believes that the widespread acceptance of a mobile payment system depends on it being able to operate with all kinds of mobile phones, including smart phones of all types, and legacy cell phones.

[0005] What is desired is a mobile payment system that operates with all kinds of mobile phones. A mobile payment system that enables a merchant's POS system to accept a payment that is assisted by a user's mobile phone is desirable, regardless of the kind of mobile phone or mobile device. Further, enhanced verification of the user's identity is desirable using such a mobile payment system. Therefore, it would be advantageous to provide a way to utilize mobile phones or communication devices to conduct transactions between two parties while avoiding the need for physical cash currency, credit cards.

[0006] Accordingly, there exists a dire need to provide a new, technically advanced and improved system and method that uses standard mobile phones to enable payment at a merchant's Point-Of-Sale (POS) system.
