Topic: MFRC 522 RFID CARD PROBLEM (Read 252 times) previous topic - next topic


hi all  :)

I  bought an RF ID and only one card out of 2 was working. How do I install the second ? (the second does not work). I need more than one card.


Buy a working set. Cheap Chinese sets tend to have such problems. As you didn't specify which set you bought, I simply assume it was such one.
