Weight is used to help identify key and ring combinations authorized to certain persons. This is done by associating a weigh scale with each storage box for key and ring combinations, all of which have different total weights. The weights of all the key and ring combinations are registered with a computer, along with authentication and storage information. Then as key and ring combinations are removed from or returned to a storage box, they are weighed on scale 25 so that a computer can compare the scale weight with a registered weight. For any discrepancy, the computer can initiate one of many security actions. |
