I bought 100 pieces of RFID reader from a vendor for cheap. Now I got to know it is not compatible with our code which works fine with RFID readers with firmware Version: 0x92 =v2.0. 

The RFID reader I bought have firmware version 0x12=(unknown).

How can I update the firmware of my RFID card reader ? If it is possible then how can I do it ? what tools and software will I need to update the firmware on these RFID reader.  Please guide me NXP community.

Hi Davinder,

Actually the correct version info is like below:

There is no 0x12 for version number, which vendor did you buy from? I guess it is a counterfeit.


Have a great day,
