Amazon Go

I hate it when companies offer a "how this works" section that doesn't actually tell you a damned thing about how it works.

* How does my Amazon account get associated with the items I take?

* How are items detected when leaving the store? If my friend and I walk out side by side, how does it know (if it does) which items are mine and which are hers?

* What happens when someone picks up an item and leaves without first doing whatever check-in/registration/setup is necessary?

These are purely assumptions based on what I saw on the video alone:

>If my friend and I walk out side by side, how does it know (if it does) which items are mine and which are hers?

Looks like the entry/exit is the same type of set-up you find at most large office buildings with the tap in/out gates (see screenshot: http://i.imgur.com/e7fDglY.jpg). I assume it only lets one person out at a time which also suggests your friend could only enter the store if they had an amazon go account and tapped in themselves.

>What happens when someone picks up an item and leaves without first doing whatever check-in/registration/setup is necessary?

Again, based on those gates, I'd assume you can't actually access the store without going through the necessary set-up first.

Personally, I'd like to know what happens if/when my phone battery dies in-store.
