Abstract
The IC card sets a status bit, to which an update command including write data is allotted, at a processing start state if receiving the update command from a host apparatus, updates a data region based on control information including information on a previous control region, sets the status bit at a processing end state, and finally transmits a response message to the host apparatus. When restarted if an update processing was interrupted, the IC card prohibits a write data update processing and transmits an error signal to the host apparatus if the status bit is set at the processing start state, and completes the update processing and then transmits the response message to the host apparatus if the status bit is set at the processing end state.
