- bluGill 3y agoWe don't need to verify everything though, just extract the vaccinated/not field which is probably in the same location on every QR code (or at least it should be possible to make it in the same area), and maybe the name of the person the QR code is for.
- 418tpot 3y agoThe signature is the whole point of the QR code though, otherwise someone could just trivially create a QR code that has their name and "vaccinated = yes".
