Simply erase the person’s code, and they no longer have access to the facilities.
Fingerprint locks operate via thermal or optical scanner and can be biometric, pin code or a combination of the two. Once your finger tip is pressed against the scanner, it automatically memorizes and identifies each individual’s fingerprint by its unique characteristics. Once the fingerprint is recognized, the individual then types their individual code into the keypad for authorized entry. Once the lock has been activated, it will automatically reset after a few seconds, at which time the code will have to be reentered in order to deactivate the locking mechanism again.
