COVID certificate and other large NDEFs

Yeah, you can try it if you want:

dgca_verifier_app-1.2.4-acc_NFC_FIX.apk (10.0 MB)

The certification keys might not work (i.e. it might tell you your certificate is not valid even though it is) but it scans NFC tags alright.

What you need is stick the QR code string VERBATIM (including spaces and all) on a plain text record in an NDEF. The string starts with “HC1…” usually.
