Pictured here is the Salto mechanism designed to convert the humble entrance set (most common in USA) to the ultra-secure Salto RFID wireless access control system.
Also recently released (not pictured) is a cylinder designed to be used with conventional wooden and aluminum door mortise locks.
Certainly these products are not cheap, but the convenience of high-security access control and audit trail features using the world reknowned Salto Inspired Access systems, separates this company from the other players.
Check them out! You are sure to be impressed.
