PURPOSE: To prevent an unauthorized usage by the other person without fail and to eliminate the need for remembering a personal identification number by a user by using collation with a fingerprint.

CONSTITUTION: A fingerprint collation part 5 receives fingerprint data, which are read from an IC card 2 by an IC card read part 3, and fingerprint data, which are read from the finger of the user by a fingerprint read part 4, and collates both fingerprint data. Then, it is confirmed that the fingerprint data is the fingerprint of the same person. Afterwards, a transaction possibility signal is generated and sent to a main control part 6. The main control part 6 controls the execution of cash transacting operation only when the transaction possibility signal of the fingerprint collation part 5 is received. Thus, since the collation of the fingerprint is used, the unauthorized usage by the other person is prevented without fail and it is unnecessary for the user to remember the personal identification number.
