I experienced this at a sushi place in Japan, before iPads or even modern smartphones existed. Each table had a touch screen device where you could browse the hundred our so different pieces. We would select what we wanted and a waiter brought it a couple of minutes later. When we were finished the waiter swiped each stack of empty plates with an RFID scanner to determine the price for each person. One could also order from a regular paper menu or pick plates from a conveyor belt.
