Wow! I’ve been told several places that the xNT is a Mifare Ultralight C NTAG216… weird!
But yeah, I’m TagInfo, the card has IC Type: NTAG216.
It also says ‘Android tech info/ tag description: **.*.MifareUltralight’
But this seems to mean something about the capabilities of the phone itself, rather than the card.
I will check out what you suggested:) thanks
