A few observations about digital vaccination certificates:

* It's really just a static QR code, you can import it into your app, but you can also make a picture of it and save it into your phones gallery. Or carry the original paper copy around.
* This unfortunately means it's easy to "steal" other peoples certificates by just scanning their code when they have it open in their app.
* The certificate will not be for your name but will that *always* be verified?

Tl;DR

You currently need to use the closed source (👎) or to verify the validity of your own certificate (or ugh, read the spec and do it manually I guess... this seems to be collecting relevant docs: github.com/stealth/greenday)

If you've done that you can use to carry around the code, or just make a photo of it, or whatever, it doesn't really matter. 🤷.

Let's hope CWA addw the verification part in one of the next versions or the CovPass sources are published...😕
