Anti-Passback
Anti-passback is an extension of the access control system that prevents re-entry during a set time interval. The device in this mode only allows the user to enter once in a given time. After a user successfully enters, the system records this event and the user can only access the system again after a specified time has elapsed. This time is set when Anti-passback is enabled.
Anti-passback modes:
“Hard” – The user cannot pass through the device in any direction for the set period of time. The user is denied access until the interval expires or access is restored by the device administrator.
“Soft” – Rule violations are only logged and may alert the administrator, but the user is allowed access.
