FlexDF2 read error

When I scan my flexDF2 with my samsung note 20 ultra I get an error message that says “unable to read NFC tag” at the bottom of my phone…anyone have any ideas as to why it won’t read correctly?
This is a relatively new implant…maybe 1 month old. Never banged it or anything.
Thank you all for your help, I very much appreciate it!

I haven’t
I’d try to write to it.
Maybe reading with TagReader works / shows some more info?

I have no idea why, but your suggestion to write to it worked! Thank you!


The xDF2 is quite the serious tag and it’s got lots of uses other than ndef data storage, so they do t come formatted for ndef. Depending on the app or software being used, writing to it will automatically create the ndef AID and format that AID with the ndef data you’re wanting to write.
