RFID diagnostic card -low frequency not working

My RFID D Card is functioning with high frequency NFC but not with low. Am I doing something wrong or is it busted?

This is likely a coupling issue. The giant coil on the RDC has a hard time picking up the girls from the XAC because the field shape is all wrong for a card or flat spiral antenna.

Okay cool, I have a kbr1 on the way, it should work for that right?

You might try rubbing the card all around and underneath. I was able to get the RDC to flash on the LF side from some angle.

Ya that antennae couples well with the RDC.

Just to clarify, the KBR1 operates at HF

Yes and I have a 125 khz reader on the way as well

Pretty sure that will end you up in jail.


You try that with an Irish girl, pretty sure you’ll end up dead. :wink:
