ABSTRACT:
The smart card with random temporary account number generation provides an authenticating system coupled with an access or transaction card, such as a credit card. The card includes first and second memory storage media, with the first memory medium containing a plurality of temporary account or authentication numbers. The card also has a biometric sensor, such as a fingerprint scanner, and the second memory stores the biometric parameters of the authorized user. A processor compares the biometric parameters with the measured biometric readings to enable the card. The processor has a random number generator, allowing for the randomized selection of one of the account numbers stored in the first memory, thus providing a temporary account number for the transaction. A remote site includes an identical random number generator and set of account numbers, allowing the temporary account number to be verified and then discarded, following the transaction.
