If you are planning on using 3rd party RFID transponders you should first test the compatibility with the MOBOTIX RFID readers (BellRFID, Keypad, MxDisplay). The flat card form factor chosen by MOBOTIX produces the best results in combination with our readers.

The sensitivity of the reader should be considered along with the technology. Some transponders use plastic materials with different thicknesses which can affect and effectively diminish the range of the transponder.
