Anti-Passback is a security mechanism that prevents a card holder from passing their card back to a second person to gain entry into the same controlled area. It's a technique used to prevent a card gaining access to an area without first having exited that area. The Anti-Passback feature sets a specific sequence in which the user’s credentials must be used in order for the system to grant access. IXM devices allow for programming of Entry and Exit parameters.

Configuring Anti-Passback in IXM WEB

1. Click Home -> CONFIG tile -> Anti-Passback app to view default settings.

2. Toggle “Anti-Passback settings” to ON to activate them.

3. The list of settings along with their functions are outlined below:

Device Type: Device can be configured as an Entry (IN) or an Exit (OUT) device type. Entry (IN) device type remembers the anti-passback status of each card in the system, the three possibilities being that the card is currently“IN”or“OUT”or its status is undefined.

Re-enter Delay: Specify the minimum duration between Entry (IN) and Exit (OUT). When a card enters into an Anti-Passback area, it will be removed and deemed to be of unknown whereabouts by the system after the delay has passed. For example an entry of 60 seconds would cause a Card to be returned to the unknown state one minute after entering the area. The user will be able to set the delay between (0-1800) seconds.

Mode (Soft/Strict): ‘Strict’ anti-pass-back restricts the entry with logs. ‘Soft’ anti-pass-back allows the re-entry but maintains the log.

Forgiveness: Forgiveness time is used to clear all cards from an AntiPassback area at a specific time of each day. At the Forgiveness time, any card present within an Anti-Passback area is removed and deemed to be of unknown whereabouts by the system. The next use of a Card at any Reader associated with the Anti-Passback area will place it back into the correct side of the Anti-Passback area.

Duress Status: When Duress Status is active, it will allow user to pass, when he/she uses one of her/his duress fingers.
