Abstract
An IC card system uses a prototype IC card and one or more production IC cards. The prototype card is programmed to execute standard read/write commands, and an initialize command that returns the card to an initial state. The prototype IC card, which can be issued, initialized, and reissued repeatedly, is used for testing purposes during the development of system software. Production IC cards are programmed to execute the standard read/write commands, and a version read command that reads out a version number distinguishing a production IC card from the prototype IC card. Production IC cards are not programmed to execute the initialize command.
