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?
Also (assuming they build reproducibly) they should be made available through f-droid, ideally identical with the upstream developers signature but veryfied to build from the published sources by an independent party. This is not possible without published sources obviously.
We did manage to do the right thing with #CWA. Why is it so hard to keep doing that? 😠
