SOLUTION: The fingerprint collating device 10 is formed of the IC card 10a, which mounts a CPU 6, the OTPROM 71 and another memory 72. In addition, a capacitance type fingerprint reading sensor 5 is provided on a surface facing the side of the user of this IC card 10a, which is used by insert-connecting an externally connecting terminal 101 to a card slot of a computer. After insert- connecting the card 10a to the card slot, the sensor 5 is touched with a finger for inputting. Next, the input is converted to fingerprint data and fingerprint data previously registered in the OTPROM 71 is called to the CPU 6 to compare/collate both of the fingerprint data with each other.
