this is my first question here and I am kinda lost.
I have a RC522 RFID module hooked up to a Raspberry PI 0 V1.1, and I have a TAG and a CARD (which I got with the module when I bought it) and I have 3 CARDS that I bought separately.
My issue is that my RFID module is reading only the card and the tag that came in the same package, and it is not reading the new cards that I bought separately.
Thank you in advance.
