Hi!
I'm trying to write to block 0 of my RFID card. I already now that most RFID cards doesn't have a changeable UID. I therefore bought a writeble card. The problem is that the RFID-reader doesn't read the card at all. I bought it here;
There is a good description of the card and it should be compatible. Why do you think it doesn't work? And how can I make it work?
The company does look like a serious one.
