ABSTRACT:
When fixed data common to IC cards is written in an unpersonalized IC card, a key card and a fixed data card holding fixed data common to the IC cards are used. When data read/write access is performed among the key and fixed data cards and the unpersonalized IC card, the fixed data is written in the unpersonalized IC card. The data read/write access among the key and fixed data cards and the unpersonalized IC card is performed by a microprocessor and a read/write controller. The data read/write access among the key and fixed data cards and the unpersonalized IC card can be performed without going through a host processor.
