Abstract

PURPOSE:To set up the size of a connected IC card equivalently to that of a normal size IC card by preparing a small size IC card smaller than the normal size IC card to be used for a normal size system and connecting an adaptor to the small size IC card. CONSTITUTION:In the case of using a small size IC card equivalently with a normal size IC card, the outline size of the small size IC card should be conformed to the normal size. In a method for conforming to the normal size, a claw adaptor 2 is used. Namely a small size claw card 1 is inserted and connected into/with the adaptor 2. Since the claw 2a of the adaptor 2 is engaged with the claw hole 1a of the card 1, the small size IC card can be used as normal size equivalent to the normal size IC card.
