Huh, maybe that explains why living in Australia, I don't understand the hate for QR code menus. Basically everywhere that has a QR code menu over here these days also lets you order and pay via the same QR code.
Honestly, as someone with young kids it's been an absolute dream. We can scan or tap as soon as we get to the table, one of us can quickly fire off some order for food and drinks for the kids, and more often than not things have arrived before we've finished unpacking the coloring books and other things to keep them occupied. At which point the adults can sit down and chat, which is usually the main reason we're out, and order at our leisure.
But you can also get someone at the table to place the order for everyone. Or often go and order at the bar (also something that you don't see too much in North America), or if its a restaurant grab a member of staff and order in a more classic way.
