Well yes, the point of this subthread is not that it's impossible to do this well, but that bars/restaurants don't seem to care whether they're excluding the occasional unlucky customer. I'm in New York City and not a single person has scanned my vax QR code: they just see a vaguely official looking app with a name that matches my ID, or a physical vaccination card (conveniently sized to not fit in any wallets).

Also, in your case, is this a federal system or a state by state one? If the latter, this sounds way worse than what NY is doing; with my CA vaccination I couldn't get in anywhere.

We have few provinces (10) in Canada, so it is easier than working and coordinating with all the states the US has.

The QR code is provincial, but it only requires minor changes to have one provincial app, look at other validation sources.

I agree that sadly, restaurants may find some metrics too high/annoying to deal with, and opt for a lost sale.
