LOB 5500 proximity cards (HI50MK-1)

Key cards are equipped with a microprocessor and contain information on its owner's authorization (where and when can he/she enter). They have a pre-programmed expiry date. Information stored on the cards is protected by a safe DES algorithm, which protects the data against any manipulation attempts. 

Cards are also issued for individual staff members of a facility. They do not have to use mechanical keys. Employee cards are valid longer, for example for one year or indefinitely.

A lost card can be disabled in the system, and a replacement card can be issued.
