Then you're hoping they won't try to match the info on the screen with the info on the paper, which is very easy to foil (just don't skip the check).

If they need to match with the info on paper it's not clear what the case for "digital id" is? If one needs to present "digital id + paper id" one can simply present the paper id as they do today.

[stavros]

They won't. They'll just check the digital ID. I said you can't fake a digital ID, you said you've faked a physical ID, which isn't really relevant.

Digital IDs can't be faked. The only way to fake them would be to convert them to physical (what you did) and hope that the physical ID gets accepted.

That's kinda theoretic discussion by now. As the whole COVID thing is behind us, we can probably look at all the money that were spent in the world to create vaccination certificates, sign them, create the distribution network, distribute the certificates, build the verifying scanners, purchase them en-masse and pay the thousands of people who were standing at the entrance of numerous shopping malls and using these scanners to check the QR codes, only to create a system that is trivially bypassed by using a jpeg file.

I'm not sure how this relates to the main argument that "digital IDs are bad because they lead to perfect enforcement".

[maratc]

My argument is that “digital ids can’t be faked” is a bad argument, and if you rely on it to prove a point then it might be a weak proof.

(Digital IDs indeed can’t be faked but usually they are a part of a process that can be easily bypassed by using something that presents itself as a valid Digital ID even if it’s not.)

[stavros]

They'll be a part of a process that can be easily bypassed until they're the only thing that's accepted.
