Thinking about your comment on QR codes --
If memory serves its not difficult on iOS to set something up to display the QR code data as text instead of acting on it.
I assume it's similarly opaque to use a URL for the same purpose, which would almost certainly be a "enter your phone / email so we can send you your URL...".
In your opinion, assuming electronic ordering, what is the best alternative to a QR code when considering privacy + ease of use?
An analog fallback via paper menu. If I'm doing sit down ordering, I don't want to order electronically unless you give me an ipad. And I don't want to pay until the meal is over. Period.
