A comment on Amazon Go. Parent comment
Probably there will be a guard at the entrance: the barrier will beep when someone enters without signing in, and the guard will stop them.
What's more interesting is that there can be absolutely no dead angles for this to work.
They might have cameras inside each shelve, mounted on top, to correlate products taken with the person standing in front.
But what if two persons stand close together, one leans over and takes something...
Or what if you go into the store with a friend or your kids. And you all pick up items which are supposed to go on your tab.
It's definitely a challenging problem.
