Contactless Credit Cards

A contactless credit card is different from an ordinary credit card. A contactless credit card uses RFID technology to store information about your account and to transfer it to the merchant. Standard credit cards carry data on a magnetic strip; when the card is swiped against a reader, the data is transferred.

It is expected that, by the end of 2006, between 35 and 50 million contactless cards will be in use in the United States at as many as 50,000 merchant locations.

The primary advantage of the cards lies in the speed of the transaction; bringing the card within a foot of the reader is sufficient.
