Abstract
An unlock system does not use a key that might be copied so that only a correct person can unlock a door and security is enhanced. Unlock records of door-lock are stored in a limited memory capacity in volume. Fingerprint data input to a fingerprint input sectiondisposed outside a doorprovided on a doorwayis detected, and the detected fingerprint data is verified against previously registered fingerprint data. If it was confirmed that the detected fingerprint data coincided with the registered fingerprint data, an unlock signal is output to unlock the door-lock, and a setting time or start-using time is stored in a storing section having a clock function.
