PURPOSE:To attain the collation of a password number without a terminal device by inputting a password number, etc., through a keyboard provided on an identification card, and comparing the inputted password number with the stored collation data (password number). CONSTITUTION:A key input part 10 including a keyboard 3 introduces a key operation signal based on the key operation to a CPU11. A clock, calender circuit 12, ROM13, RAM14, EEP-ROM15 and display drive circuit 16 are connected to the CPU11. The clock and calender circuit 12 include a crystal oscillator, divider circuit, etc., and can display the current time, month, day, etc., on a liquid crystal display device 4 as well as counting the current time. Collating data such as a password number and membership number is written beforehand in the EEP- ROM15. By comparing the number keyed-in by a card user with the password number stored in the EEP-ROM15, the collation is made whether or not the card user is a right person. |
