Finger print codes of administrators are registered to card keys and locks. One of the administrators assigns a card key to a lock and enables the card key. An user registers his finger print to the enabled card key. The user inputs his finger print to the card key whenever he wants to open a lock. The card key transmits the finger print codes of administrators to the lock when the inputted finger print matches the registered finger print of the user. The lock compares the received finger print codes with the registered finger print codes. When any of the received codes matches any of the registered finger print codes, the lock is opened. |
