I want to make sure we're talking about the same thing. When I hear people say "vaccine passport" I assume they mean "COVID-19 vaccination documentation". Is that a correct interpretation, or does a vaccine passport mean something more? If it is just "COVID-19 vaccination documentation", has there been a push to not allow the paper documentation? I've been primarily using my paper documentation without issue. As far…
I need to lead this with "I'm fully vaccinated and pro-vaccine" so nobody gets the wrong idea (I'm disappointed that this is the state of discourse) BUT... Anyone can print a piece of paper. If vaccination requirements are going to have any teeth whatsoever, they will need to be much more invasive. A central database is the minimum. You'll need holographic cards with your picture, like driver's licenses. Spot checks…
So there's no need for anything more complex than a piece of paper you can download + print. What you can't do is make a QR code of your own, change the validity reason of an existing code, or use somebody else's certificate with your own identity.
