Abstract
A method for using a smart card to gain access through an access device upon payment of a value (V) is performed by first operatively coupling the card to the access device. The access device reads a first and a second set of data from the card, and performs a first authentication process on the first set of data. Access is permitted if the first authentication process meets a required condition. Access is denied otherwise. If access is permitted, the second set of data is stored in the access device for further processing, including a second authentication process which operates on the first and second sets of data.
