Most Android phones do this automatically - and it's not too hard to write up a quick app for it to scan automatically when it detects a QR code.

My friends and I all browse together on our phones and we excitedly point out different menu items, that we can look at independently without having to cram together looking at a piece of paper. Otherwise I don't know how this is any different than having separate menus.

Randomly scrolling up/down/left/right on a tiny screen feel awful compared to just letting your eyes drift.
Scrolling through a PDF / page has always been fine for my friends and I. I'm also not entirely sure why I would want my eyes to drift when actively looking for something to eat as well?
