> Just like restaurants today that only have a QR code but no physical menu

This is partly a holdover from Covid, and just as while there are a few people walking around with Covid masks on, most people aren't wearing them any more, and there are loads of restaurants that don't rely on QR codes. QR codes do have actual advantages, but also disadvantages, so they will - and have - balance against the market's requirements.
