How to Program an NFC Tag In about 45 seconds using a free smartphone app and a couple of steps Steps. You may also reprogram or overwrite previous info on any NFC card or NFC chip. This guide breaks down each step and also has troubleshooting tips if you encounter an error.

The only 100% way to make NFC tag "read only" is to call makeReadOnly(), but this is irreversible. You can use "out of the box" solution, like: do not write data on NFC tag but instead save it locally (if data is limited to one device) or to a server/cloud (if data si global) Mifare Classic have 16 sectors,’each with up to two keys, but there are techniques for cracking the keys, depending on when the tag was manufactured. Also, it’s entirely possible that the contents are locked and can not be rewritten.

I have locked a NFC tag using makeReadyOnly () using specific app and now I want to rewrite tag only from that specific app. I have followed these documentation. https://developer.android.com/reference/android/nfc/tech/Ndef#makeReadOnly ()

This is an external app that writes UID of Mifare Classic 1k to RW NFC tags (Magic cards). It can format those tags/cards as well. Tested and it’s working but only supports 4 byte UID and doesn’t write the data/sectors of the card yet. You can read all about this mechanism in the NXP datasheet for these tags in section "8.5.2 - Static Lock Bytes": https://www.nxp.com/docs/en/data-sheet/NTAG213_215_216.pdf So amiibo writers need to set this read-only flag to create a functioning amiibo NFC tag. If you wanted to, someone could make an IPS patch for the NFC service to remove that read-only flag check. Then you could make NFC tags that don't have the read-only flag set and they would work on your Switch and you could re-write to them.

If you’re using Apple Shortcuts to trigger the action, it doesn’t need to be writable since that only uses the tag’s id. I would suggest something in the ntag21x family: ntag213, ntag215, ntag216.
