Abstract
Upon receiving a read command from an external device, a control element in an IC card determines whether transmission data to be stored in a transmission buffer area is the data that has been read out from a transfer permission area. When determining in the determination that the data is the data that has been read out from the transfer permission area, the control element stores the data in the transmission buffer area and then outputs it to the outside as a response to the read command. On the other hand, when determining in the above determination that the data is not the data that has been read out from the transfer permission area, the control element aborts the operation.
Claims9
A portable electronic apparatus comprising:
- a memory that stores data;
- a communication section that performs data communication with an external device;
- a transmission buffer for storing the data to be transmitted to the external device through the communication section;
- and
- a control element that stores data in the transmission buffer in the case where the storage area in which the data to be stored in the transmission buffer has been stored is a transfer permission area in the memory;
- whereas prohibits data from being stored in the transmission buffer in the case where the storage area in which the data to be stored in the transmission buffer has been stored is not the transfer permission area.
