With its small size,Contactless Small Module can easily be installed in any standard-sized single-gang electrical switchbox without the hassle of drilling wall holes or reconstructing building circuitry. This entails a very simple and quick installation of a powerful contactless module that is ideal for a broad range of applications, especially physical access control and time and attendance.
With a mere wave of a contactless card, one can enable to give off prompt read or write signals through its self-contained LED/buzzer, and at a blink of an eye, the relay is triggered to open the door for an authorized person attempting physical access.
