Hi,
I recently got an NFC implant in my hand (NTAG216), and cloned an Amiibo onto it. Now, I am unable to overwrite the chip in my hand. For an Amiibo to work on a Nintendo console, Nintendo requires it be in write-protected mode, which it looks like my tag has succumbed to. However, my Nintendo Switch does not recognize the implant in my hand – there is no error message or anything, it just doesn’t read it. This makes me think that the process was borked and perhaps not all is lost. Is there any way I can overwrite the data on my hand? If not fully overwrite it, can I at least still add records (custom messages) for people to see when they scan my hand? I read through https://nfc.toys and see that I can get the NFC Password for this tag, and possibly write to it, but I would like someone more knowledgeable to instruct me with what to do.
Here is the info and memory of the NFC tag on my hand:

I’m a complete novice with NFC, so I realize I probably screwed up big time. Sadly, I only stumbled onto the Dangerous NFC app after this all went down. It was a great learning experience, but I truly feel bummed out that the implant I got 24 hours ago is now unusable. I’m still holding out hope that not all is lost! Any and all advice would be appreciated!
