ABSTRACT:
At each of a plurality of transit readers of a transit system, for each of a plurality of riders, where each rider seeks to conduct an access transaction with the transit system for access into the transit facility by using a payment device issued by an issuer in a payment system, data is read from the payment device. The data includes an encryption code that uniquely corresponds to the payment device and was created by the issuer using one or more encryption keys and a predetermined algorithm. A check will be performed, remotely and/or locally, of one or more lists of other encryption codes to determine if the encryption code is on the list. On the basis of whether the encryption code is on the list, the rider is permitted access to the facility of the transit system. The payment device need not be changed for the rider's fare. Decryption of the encryption code read from the payment device is not required to complete the access transaction.
