Description

INTEGRATED POINT OF SALE PAYMENT TERMINAL

Technical Field

[1] The present invention relates to a single point of sale terminal generally and more particularly, to an integrated, wireless and handheld point of sale terminal relating to processing credit card and stored-value card transactions that are compliant to both CEPAS and EMV standards. Background Art

[2] The present invention relates to the processing of credit cards and stored-value cards, namely Ez-link card transactions in the field using an integrated, wireless and handheld payment terminal. Traditionally, credit cards transactions and stored-value card transactions are accepted separately on payment terminals.

[3] Wireless, handheld payment terminals for accepting credit cards are well known in the art. Generally, there are two forms of credit cards, namely, Magnetic stripe cards and smart cards. A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometime called a magstripe, is read by physical contact and swiping past a reading head. A smart card, chip card, or integrated circuit card (ICC), is any pocket-sized card with embedded integrated circuits which can process data.

[4] Ez-link card is a stored-value, contactless smartcard based on Sony's Felica smartcard technology, and compliant on the new Singapore Standard for Contactless ePurse Applications Specifications (CEPAS). It is used for payments especially for transportation in Singapore. The Ez-link card is a thin, compact card conforming to ISO/IEC 7816 card dimensions, similar to a credit card.

[5] The Ez-Link card operates on a radio frequency (RF) interface of 13.56 MHz at 212 kbit/s. It employs the Manchester bit coding scheme for noise tolerance against distance fluctuation between the card and the contactless reader, and implements the Triple DES algorithm for security. It allows for communications at distances up to 10 cm. They are often used when transactions must be processed quickly or hands-free, such as on mass transit systems, where smart cards can be used without even removing them from a wallet.

[6] An Ez-link contactless reader is used to perform financial transactions on Ez-Link cards. It is a communication device that reads and writes to a Sony type C contactless card and a CEPAS type B contactless card. It also interfaces with an external controller via a RS232 or a USB interface. The External Controller is required to be integrated to the Ez-link contactless reader/writer using a message Application Programmable Interface (API). Examples of external controller are Point-of-sale terminals, photocopiers and kiosks.

[7] In a sale of goods by a merchant to a consumer, there are various point-of-sale devices available to the merchant which may be utilized to complete the transaction. Earlier method of solving this problem was to integrate the Ez-link contactless reader to the point-of-sale terminal, such as credit card payment terminal. The integration was done by developing a software application for the credit card payment terminal and connection was done via a RS232 serial port. The credit card payment terminal acts as the controller for the CEPAS Ez-link contactless reader. This method of integrating credit cards and stored- value cards create various problems. Disclosure of Invention Technical Problem

[8] One problem is various applications are needed to be developed due to the different platforms used by various credit card payment terminals in order to integrate the stored- value terminal to the credit card terminal. Some common payment terminals are from Hypercom, Verifone, Ingenico and many others. This increases the time and cost of implementation. Furthermore, merchants are required to pay higher cost for two terminals. For merchants on the move, such as taxi drivers, carrying two terminals to process credit card transactions and stored-value card transactions, particularly Ez-link card transactions, becomes bulky and inconvenient. Technical Solution
