Wow, some great replies. I am working through the links you gave me and building up my knowledge base. Thank you all.
No I haven’t and if you’re referring to the same thing Amal was in the thread Looking to buy xNT - I see the beta app doesn’t work my reply was:
My NTAG216 shows 55 48 00 00 = unprotected. What is BCC1 that mine shows 55? For clarity this is not an old xNT but a non-DT, NTAG216.
Is that (Line 2) the data I should be changing?
