Do NFS labels have overwrite protection?

Question

NFC

Good afternoon, please tell me if there are NFC tags without the possibility of rewriting?

Answer 1

of course there are, I'm not very good at different labels, but I know very well that Mifare Classic will do this job perfectly. All you need to do is write the card, generate B keys, write them to all sectors, and encode ACs into the card such that it does not allow anything else to be written to the card and read key B. Done
