Draper, UT | August 26, 2021: ProdataKey (PDK), manufacturer of the leading cloud access control platform built for mobile, has added Anti-Passback to the programmable features of its pdk io cloud access control platform. Anti-Passback requires individuals who have scanned through an entry reader to scan out through a corresponding exit reader before their credentials can be used to re-enter the premises. By requiring credentials to be used in an “in–out–in” sequence, cardholders cannot “pass back” their access card or credential-enabled mobile device to another person after entry, allowing them to enter too.

Anti-Passback rules are defined through the pdk.io software. They may be applied to locations where users pass through designated entrances and exits, like parking garages, and secure areas such as data centers and laboratories that regulate both entry and exit of workers. 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, 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.

“For some PDK customers, credential misuse is a serious concern. Anti-Passback provides a means to deter and monitor abuse of their facility’s security protocols while reducing the risk that unauthorized personnel gains entry to high-security areas,” explained Jeff Perri, ProdataKey’s President and COO. “Like all other pdk io features, administrators can easily set up and manage Anti-Passback rules through our unique, mobile-first environment.”
