A mullion in access control is a slender, vertically mounted card reader designed specifically to fit on narrow door frames, or “mullions”. These compact readers are ideal for glass doors, metal frames, and tight spaces where standard-sized readers won’t fit, offering full functionality for RFID, Bluetooth, and PIN access. 
Key Aspects of Mullion Readers:
  • Dimensions: Typically very thin (often around 1.5 to 2 inches wide), allowing for installation on narrow aluminum or glass door frames.
  • Installation: Usually surface-mounted, but can be flush-mounted in some applications.
  • Technology: Supports contactless technologies including HID prox, DESFire, MIFARE, and mobile credentials (smartphones).
  • Usage Examples: Used on entrance doors to apartment buildings, office entryways, elevator control panels, and for securing amenity areas like gyms or pools.
  • Synonyms/Related Terms: Slimline reader, mini-mullion reader, narrow-stile reader, or simply card reader mount. 
These readers are often utilized because they provide a sleek, aesthetically pleasing, and secure option for modern building access control systems.
