Make NFC readonly

Dear all, i would like to know if anybody knows if it is possible, maybe with an extension, to make nfc tag readonly.



Hi @Fabio_Maroni,
You can protect with password your tag but this depends on which rfid tecnology.
with this extension

You can protect with password Mifare Classic Tag and Mifare Ultralight EV1 Tag.
On Mifare Ultralight EV1 there is a bit to make a the Tag readonly but I did not implemented this function
Best Regards
