The Physical Security Interoperability Alliance (PSIA) and several other partner companies in access control and biometrics demonstrated the way a cloud-based PLAI (Physical Logical Interoperability) agent can connect five physical access control systems (PACS) and two biometric systems relying on a single source to creates a physical access control  interoperability environment that allows an organization with disparate security systems to utilize identity data across locations and systems seamlessly.
