Most of our readers can be configured to communicate in 26bit or 34bit.The most important thing to ensure compatibility between your card reader and controller is the bit length. The Malibu Access Controller can currently handle 26 and 34 bit Wiegand devices.Is my RFID card reader Wiegnad compatible?Most card readers show the Weigand bit length on the back of the RFID reader.
