PROBLEM TO BE SOLVED: To provide a password number collating system which can singly input number in an IC card processor, incorporates the number is the command of password number collation transmitted to the IC card, prevents the identification number from appearing between an information processor and the IC card processor and prevents illegality such as a wiretap and the forge of the password number. SOLUTION: The IC card 90, the IC card processor 10 having an password number input device, and the information processor 21 are provided. The IC card processor 10 obtains the password number from the password number input device by a first instruction code, stores it in an internal memory, generates third instruction code by a second instruction code received through the information processor 21 and by the password number and transmits it to the IC card 90. |
