JANUS Bag Search randomly puts cards into an anti-passback area and marks their status as ‘Failed Anti-Passback’. This is done at the same time that a valid entry is registered and is determined upon the probability settings that have been pre-defined e.g. 1 in 10, 1 in 20 etc
Upon an egress attempt by any card in this anti-passback area, the system will prohibit them from leaving and their details will be flagged at a local PC which is monitoring the Bag Search system. Verification at the PC will reset the user’s anti-passback status who will then be able to egress in the normal way.
