You would be surprised how well app screenshot in full screen with the qr code works.

Seen this many times with covid vaccination passes.

No idea about this app, but presumably that's the reason why quite a few apps show animations and a rotating code word alongside the QR codes, so staff can easily spot that kind of thing.

Doesn't work for these tickets since they're generating new underlying values as time passes.

Even Costco has self-modifying barcodes now, so covid vaccination passes are behind on the times.
