The anti-passback feature is designed to minimizes the misuse or fraudulent use of access credentials such as passing back card to an unauthorized person, or tailed access. The anti-passback function establishes a specific sequence in which cards must be used in order to grant access. The person should exit via the door in the anti-passback group if he/she enters via the door in the anti-passback group.
