ProdataKey has added anti-passback to the programmable features of its pdk.io cloud access control platform. Anti-passback rules are defined through the pdk.io software. They may be applied to locations where users pass through designated entrances and exits, such as parking garages and secure areas. The feature may also be applied at turnstiles. Should someone swipe a credential in a sequence inconsistent with the anti-passback rule, a violation is logged and reported, and, depending on how the system is programmed, the second entry is denied. Administrators can set violation time frames for any length, including no expiration. Establishing a violation window rather than an indefinite timeframe effectively prevents users from “passing back” their credentials at time of entry but allows the system to reset itself —perhaps overnight. Credentialed workers who inadvertently fail to scan out will therefore not find themselves locked out the next day. Anti-passback is compatible with any pdk hardware, including pdk, touch and red readers.
