ABSTRACT:
A portable storage medium issuing system writes plural issuing data in storing regions in a portable storage medium. The system includes a first memory to store plural secret data, a second memory to collate input secret data with the secret data stored in the first memory and stores a secret data out of plural secret data, which is collated and agreed with the secret data stored in the first memory based on the collated result, a third memory to store the plural issuing data and secret data which has been set corresponding to each of plural issuing data and requires the collation before writing into the portable storage medium as collating conditions. The collating condition stored in the third memory is compared with the collated status stored in the second memory. When the collated status satisfies the collating condition based on the result of this comparison, the issuing data in which the collating condition has been set in the storing region is written in the portable storage medium.
