Popularly known as APB by access control professionals and enthusiasts, Anti-Passback is a popular security feature that prevents the unwanted use of ID cards and blocks re-entry attempts. Continue reading this article to learn more about this feature, how it works, and its helpful benefits.

What is Anti-Passback? – Definition

Anti-Passback-This-Access-Control-Feature

Anti-passback is a simple access control system feature that doesn’t grant consecutive entries to one access cardholder. Here, the concept is to avoid the misuse of access cards and prevent multiple people from accessing highly secured zones with illegitimate means.

Though it may sound confusing sophisticated at first, Anti-passback is a useful security feature and comes integrated into different types of access control systems today. The Anti-passback feature requires two access points (one for entrance and the other for exit) for successful implementation.

How Does This Feature Work?

The-anti-passback-Feature-Work

The anti-passback feature requires using access cards in a specific sequence and two access readers to work successfully. For every use of access card on the entrance (in) access reader, there must be a use of access card on the exit (out) access reader before using the entrance (in) access reader again. For proper execution, this in-out-in-out sequence should be followed.

Let’s understand this security feature with the help of an example.

John enters the office, by tapping his access card on the entrance gate access reader and gets out by tapping the access card on the exit gate access reader. Here a sequence “in-out” is working well.

Now suppose, John taps the access card on the entrance gate access reader and doesn’t enter his office. Instead, he taps the entrance gate reader again.

So what do you think will happen here? Will John get access?

Well, the answer is John will not get access, because the access reader has utilized the anti-passback feature to block his access. The reason being, he didn’t enter the office and tapped on the exit entrance reader, so an “in-in” sequence has occurred instead of an “in-out” sequence.
