<p>PURPOSE:To issue an IC card excellent in confidentiality and reliability by executing an action test program only through activation information written from an external part to a volatile memory, etc. CONSTITUTION:An input output device 1 receives the data block transmitted from a test device and sends it to an identifying device 2. When it is discriminated that the mode identification information of a data block stores the activation program to activate the test program, an activation program writing device 6 is activated by the device 2 and the device 6 writes the data to an activation program area 51 in a RAM 5. Thereafter, the instruction to activate an action test program 41 send from the device 2 is sent to an arithmetic processing part 3, decoded by the processing part 3 and an activation program executing device 7 is activated. Thus, an activation program is executed and the program 41 is executed. Thus, only at the time of confirming the IC card action, an activation program to activate the program 41 exists.</p> |
