You will be happy to know that I have fixed the NFC code in the EU COVID certificate verifier reference implementation app. It now successfully scans COVID certificates off of NDEF records.
Sooo… I will be submitting a patch to the developers, and since all national COVID apps in all European countries are derivatives of that reference app, all we EU residents will soon have officially the option of presenting our implants for scanning anywhere in Europe.
I’m mighty proud of that one
