Amazon Go

I wonder how they plan to deal with fraud... some kind of check-in process instead?

I was thinking that, but then realized that the concept of fraud doesn't really apply in the way we're used to. I mean you're allowed to walk into the store, take anything you want, and then walk out.

How would you even define fraud in that context? Presumably there are things you could do to confuse or mislead the technology, but it seems to me that as presented the onus is on Amazon to just charge you the correct amount based on what you leave the store with.

Presumably they'll want to deactivate the accounts for people who don't settle their bills, and they'll want to keep out folks who don't have accounts. This seems attackable to me, probably because they haven't released enough details about how it works.
