A smart card comprises a storage unit in which various data are stored, a communication unit to perform data communication with an external apparatus, and a processing unit which executes processing corresponding to a command received via the communication unit. The processing unit of the smart card detects data judged to have data abnormality from the data stored in the storage unit in a case where the command received from the external apparatus is an abnormal data confirmation command, and notifies the external apparatus of response data including information indicating the data in which the data abnormality has been detected by the detection.

Portable electronic apparatus, processing apparatus for portable electronic apparatus, and data processing method in portable electronic apparatus

An IC card has a memory for storing data having a nest structure in which lower hierarchy data expressed in a predetermined format exists in upper hierarchy data expressed in a predetermined format. The IC card provides direct access to only the desired lower hierarchy data from among a plurality of lower hierarchy data existing in the upper hierarchy data with respect to the data having a nest structure stored in the memory.

Apparatus for direct access to only specific lower hierarchy data in a nest structure

In the case of an IC card having a decoding key for decoding data and an encoding key for encoding the data which are generated inside or set by an external unit, when a key takeout instruction for taking out the decoding key and encoding key in the IC card to an external unit is input, the decoding key and encoding key are encoded by a plurality of other keys set in the IC card and then transmitted to an external unit.

IC card terminal unit and IC card duplication method

The present invention provides an IC card issuance system that issues an IC card by writing issuance data including an ID specific to the IC card into a memory of the IC card, wherein, when reissuing an IC card identical to an issued IC card, an ID of an IC card to be reissued is read out from the IC card. A record having an ID that corresponds to the read out ID is retrieved and output from an issuance file having stored issuance data of the issued IC card therein, and reissuing of the IC card is based on the output record (issuance data).

IC card issuance system

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.
