ID CARD PROCESSOR

PURPOSE:To curtail the memory capacity required for storage of verified data in an ID card reader, and to improve a speed for verifying this data, in an entering/leaving management system. CONSTITUTION:In an ID card, an ID number itself is not written but a registration arrangement number consisting of a serial number whose address is converted easily is written in advance. Also, in a storage position in which its arrangement number is an address, binary data of permission/unpermission, etc., to the card is stored in advance. In such a state, this processor is constituted so that at the time of passing, the registration arrangement number read from card is converted into an address, and permission/unpermission of entering and leaving by the card is verified by the binary data of its address.
