I recall all the chat, maybe twelve to fifteen years back when Asian use of QRs took off, thanks to ready availability of mobiles. There were impassioned arguments that it might be fine in those markets but it would never catch on in the West because it was not appealing to consumers who wouldn't want them all over magazines and menus. I never bought that, as fairly quickly the phones came with built in recognition and it was just a matter of time. We saw at table ordering thanks to COVID and many products added QR for consumers even if the shops hadn't pushed it (in the UK at least)
