Access control – The CardLink concept

A typical access control system contains a number of online (networked) and standalone (non-wired) doors. While the latter reduces the cost and hassle of cabling, it increases workload, as the operator has to go to each door to manually update access rights or to upload door history.

CardLink solves this problem, as it simplifies the process of updating access rights on non-wired devices, thus keeping operational costs low. Instead of updating access rights manually at each door, the operator instructs the users’ access cards to carry those instructions to the doors. Users collect these instructions update terminals situated in strategic locations, e.g. at the staff entrance, in lift lobbies or in the canteen.

To reduce the security risk if a badge is lost or stolen, access rights can be given for short periods of time, e.g. two hours for visitors and eight hours for employees. In addition, these access rights are ‘validated’ automatically at the update terminals each time the badge holder enters the premises and ‘de-validated’ upon exit.
