PURPOSE:To prevent an input error by registering a secret code as a regular secret code when the secret code inputted several times is the same in case the secret code for a secret code collating function of the portable media is registered the same. CONSTITUTION:When a user inputs the secret code number with a ten-key 42 of a secret code number input part 41 of the IC card handling machine, CPU3 of an IC card checks the reasonability of the first supplied secret code of the user, stores to RAM5 and outputs the matter to a control part 51 and CPU11. As a result, the control part 51 displays the first secret code at a secret code number display part 48. Next, by the guide of the setting of the second secret code number by CPU11, the user inputs the secret code number by the ten-key 42 of the secret code input part 41. CPU3 collates, at a secret code collating part 7, the number of digits and the number of the first secret code number stored in RAM5 with the second secret code number, and when coincidence is judged by CPU3, the secret code number is stored at a data memory 4 and a consistent signal is outputted to the control part 51 and CPU11. |
