PURPOSE: To easily recover error by transmitting error information and information, which specifies a portable storage medium which was in course of issue processing at the time of the occurrence of error, to a control means.

CONSTITUTION: If some error occurs during the IC card issue processing, an IC card issuing machine 10 transmits information, which specifies the IC card which was in course of issue processing at the time of the occurrence of error, to a higher-order device 12 together with information indicating the classification of error. Therefore, the higher-order device 12 accurately recognizes the IC card 1 whose issue is hindered and error by which this issue is hindered. Consequently, processing corresponding to error is performed, and the issue processing of the IC card 1 is performed again after error recovery. Thus, a prescribed portable storage medium is surely issued.
