PSIA successfully demonstrated interoperability between five vendors, with its PLAI specification, at ISC West 2019. The flawless demonstration showed commercial versions of PLAI in Johnson Controls, Software House (C?CURE 9000) and Lenel/S2 (OnGuard) systems. Three biometric vendors, EyeLock, Idemia, and Princeton Identity, and all were able to share credentials across the five systems via the PLAI Agent, a commercial version which is now available from Cruatech.
