Contactless credit cards
Deepak Bagai

CREDIT cards have penetrated the grassroots of modern economy and given a boost to the concept of plastic money. The account information is stored on a magnetic strip, which is swiped by the card reader when a transaction takes place. The traditional method involves the handing over of the plastic, to the retailer, by the customer for card swiping and the corresponding approval from the bank. The receipt generation process follows this. Mastercard and American Express are in the process of testing the "contact less" versions of their credit cards for the launch in the market, which is supposed to be fully in place by 2005 if things go as planned.

The contactless credit card needs only to be held near the card reader for the sale to take place. These cards update their data on chips embedded on the plastic. It may actually not leave the hand of the customer. These cards differ from the existing magnetic strip cards as they have chips tuned for radio frequency identification (RFID). The cardholders need not even remove the card from their wallets. The biggest merit in such cards is the speed and security, as the card never leaves the hand of the client. The contactless cards do not have any battery and are triggered in the vicinity of the card readers’ electromagnetic waves. A small radio antenna is built in the card to transmit the information instantly to the reader. The transaction then goes through the credit card network in the similar fashion as if the card has been swiped.

The contactless cards will come to the mainstream if the common standards are at place. EMVCo has been formed to ensure that a single terminal and card approval process is developed which ensures cross payment system interoperability through laid down EMV specifications. The EMV standard has been developed by Europay International (now Mastercard Europe), Mastercard International and Visa International to standardise operations among various payment systems. EMV is a global standard for the design, security, and functionality of smart card terminals and applications that applies to credit card issuers, processors and terminal manufacturers.
