  • Patent number: 6708878
    Abstract: When a user accesses an IC card system, the user intentionally registers processing or actions necessary for an IC card to an IC card management system, or the system determines a predetermined state to register the processing to the IC card management system. The IC card management system beforehand delivers the actions to an IC card terminal. Thereafter, when the user inserts the IC card of which the necessary actions have been registered to the IC card management system to the IC card terminal, the IC card terminal executes the actions corresponding to the IC card.
