发明名称 LICENCE-CARD-CONTROLLED CHIP CARD SYSTEM
摘要 The invention relates to a chip card system in which the chip cards (AK, LK) have at least one internal processor (P) and a fixed store (S) at least for one operating system of the processor (P). There is a plurality of user chip cards (AKn), the processors (P) of which can obey users' commands only after clearance, and at least one licence chip card (LK), in the fixed store (S) of which a limitable number of clearable users' chip cards (AKn) can be handled. The internal processor (P) can be cleared by at least one read-write station (AKG) for chip cards (LK) in a user's chip card (AKi) if the number of clearable users' chip cards (AKn) in the store (S) of the licence chip card (LK) has not yet been exhausted. The number of clearable users' chip cards (AKn) is then decremented in the store (S) of the licence chip card (LK).
