Abstract
An IC card issuing apparatus sends a key setting command accompanied with a key to an IC card. The IC card receives the key setting command and the key accompanying the key setting command is set to the IC card. The IC card issuing apparatus sends a special key setting command accompanied with a key to the IC card. The IC card receives the special key setting command and the key accompanying the key setting command is set to the IC card. Further, a set key process result is generated based on all keys set to the IC card. The IC card sends the set key process result to the IC card issuing apparatus. The IC card issuing apparatus receives the set key process result, and confirms whether a normal key is set to the IC card based on the set key process result.
