Product Name
Proximity Card Access Control Terminal

Model No.

Catalog     Picture  


The AC903 is a simple yet powerful stand alone Access Control Terminal based on Radio Frequency Identification (RFID) Technology (also called Proximity).  The AC903 is designed to be...
...easy to install. Installing the AC903 is fast and hassle-free.   The AC903's main connector is conveniently located and clearly marked.  There is no need to solder or crimp- just use a screwdriver to connect the wires.
...simple to program. The AC903 is programmed from its own keypad and requires no external programming unit or computer connection.  Despite being simple to use, the AC903 has many programmable features.  Users can be added and deleted on the fly, several access modes are available, and the Terminal can be customized to work with different external hardware and configured with additional options that will further enhance the AC903's performance.
...convenient. There is no need to swipe the card  with RFID technology- simply pass the card in front of the Terminal (sometimes without taking it out of the wallet).  Unlike conventional magnetic cards, RFID cards do not wear out with use (reducing the number of replacement cards), because reading the card does not require contact.
...and very, very reliable. Equipped with heavy-duty water-resistant keypad, powerful relays, reliable memory, glitch-free sensors and contact-free card reading technology, the AC903 is guaranteed to provide years of service-free operation.
