Is it possible to overwrite the uid on the map?

Question

Arduino

There is a card, you can overwrite it on it, using arduino and rfid522?

Answer 1

Depends on the card.
In the vast majority of cases, you can't.

Answer 2

By standard, you can't.
But the Chinese said "if you can't, but you really want to, then you can" and released cards that support overwriting block 0.

Answer 3

With a standard label - it is impossible. But if you enter <label_name> white or <label_name> zero in the search, you can buy the corresponding label or even take "for beer" from the player who has played enough.
Just don't experiment on the subway with Mifare Zero, okay?;)
