In my dept at work we have a wall of cabinets that house various testers, power supplies, o-scopes, and stuff. Some people do not adhere to the sign out sheet posted on the door on the cabinet. As an employee we are issued a gerenic RFID tag to enter doors and an ID badge with a mag strip for clock in/out. The features I would like to see is an email sent to the person that barrowed the item and the dept head of who took what, a key pad to lock/unlock the doors and too track who is opening the door.
