I had surgery a couple of months ago and the hospital entry here in QLD had their QR checkin code printed on a novelty-cheque-sized piece of cardboard sitting on an artist's easel outside the entry to the hospital foyer. I could scan it from like 10 metres away without any zoom. It was fantastic. Many places I've seen have taken a 'defence in depth' approach, where they put up numerous copies throughout their entryway so that multiple sets of people can check in simultaneously. Either on top of the pylons holding barrier ropes, or against multiple doors in an antechamber, etc. That also works well for getting people through.
