IC card, IC card reading/writing apparatus, host for an IC card reading/writing apparatus, IC card system, and method for allowing use of multiple vendors in an IC card system

摘要

An IC card (1A) includes a card body (11A), a memory section (12A) buried inside the card body (11A) and adapted to store data information and control information, and an interface section (13A). The interface section (13A) inputs the data information to be stored in the memory section (12A) and outputs the data information stored in the memory section (12A). The interface section (13A) also outputs the control information stored in the memory section (12A). The memory section (12A) stores control information including card maker identification information to be reported to the outside. Therefore, it becomes possible to automatically identify the maker of each IC card (1A), so that the IC card (1A), the IC card reading/writing apparatus (2A), etc., can be procured from multiple vendors when an IC card system is constructed.
