ACM 125KHz RFID Key Fob Proximity Access Control Tag

The ACM 125KHz RFID Key Fob is a compact proximity tag designed for use with 125 kHz RFID access control systems. It allows authorised users to gain entry to secured areas by presenting the key fob to a compatible RFID reader connected to an access controller. Each key fob contains a unique factory-programmed identification code, which is recognised by compatible access control readers. When the fob is presented within the reader’s detection range, the system verifies the ID and activates the connected door controller to grant access. Operating at 125 kHz, the tag is compatible with many standard EM4100 / EM4102 proximity systems, making it suitable for a wide range of door entry systems, access control keypads and standalone RFID readers. The fob is constructed from durable ABS plastic and designed to be water-resistant, allowing reliable use in everyday environments. Its compact keychain format makes it easy to carry on keys, lanyards or ID holders for convenient daily use. These RFID key fobs are widely used in office buildings, residential access systems, parking access, security doors and employee identification systems, where simple and reliable proximity authentication is required.
