I had it verified constantly, both in airports and (on a trip to Italy) on pretty much every restaurant or bar I went to. I think it was only once that they were fine with showing it, all the others had scanners.
I don’t go out a lot, but I’ve had no verification in 2 restaurants and one bar so far. Just a check that it’s scrollable in one case, otherwise just that the name sounds like it could be mine. No scanning of the QR code, no ID check.
And I’m not even using the official app for Germany, but the "Corona Tracing" fork.
Same here. Only when entering a non-EU country after flying there, they checked with a scanner. Nowhere else. Not that I do a lot of risky activities at the moment, though, so perhaps I've just gotten unlucky with the places where it should have been checked.
Some places have no checks at all; other places you need to show one of {show the QR code, use the Luca contact tracking site, fill out a paper form}; at least one needs the QR code and a valid ID card (not sure what, but excluding the health insurance cards despite those being photo ID).
They didn’t scan the QR codes in the places I’ve been to, they just looked at them. This isn’t the first time I’ve seen cargo-cult attitudes to how the content of mobile or tablet screens relates to security.
