Abstract
A portable electronic device contains a memory having first to third memory areas and a CPU. A plurality of identification number data is stored in the first memory area. The portable electronic device receives identification number data from an external device. The CPU verifies the identification number data received by this device with the identification number data stored in the first memory area. Verification results are then stored in the second memory area. The portable electronic device also receives instruction data from the external device. Control data corresponding to the instruction data and representing a plurality of identifiers are stored in the third memory area. Each identifier indicates whether or not identification number verification is required and whether complete or partial identification number verification is required. The CPU then refers to the verification results stored in the second memory area in accordance with the control data stored in the third memory area after the instruction data has been received. Finally, the CPU executes the instruction data in response to the verification results.
