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 fir…

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…

Or if you lose your internet connection. or if your app crashes.

What happens when you don't have enough money available to Amazon to cover all the things you grabbed? Do they give you a window to return items before banning you from the store and/or notifying police?

What happens if you trash a hotel room?

I like the video. But I wonder where they put all the middle aged and elderly customers. Probably in the food.

There are zero children in the video, as well.

I don't think there are many children (or elderly for that matter) among Amazon employees.

When I started reading the description, I thought: "someone finally delivered on that RFID pitch of just walking out of the store". Was surprised that it's actually computer vision.

The problem is RFID, while cheap... is not cheap enough. It's still most economical to keep RFID on the case level.

It's also really easy to take the RFID tag out of a product. Machine vision is likely the cheaper/more secure approach.

I worked at a grocery store for several years, and one thing I recall is customers CONSTANTLY putting items back in a random aisle, rather than where they found it. I wonder how this tech deals with that? Maybe they figured that out, too. But I was amused in the video when I saw the customer putting it back where it belonged, because that's not how I remember that going... All that said, this is fantastic and excitin…

> I worked at a grocery store for several years, and one thing I recall is customers CONSTANTLY putting items back in a random aisle, rather than where they found it. If the incentive is reducing the chances of being charged by the system for an item they didn't buy, you bet people will put stuff back where they found it.

Would it be feasible solution to have drop-off basket at the counter for items that you do not want to buy? Also there could be refrigerated and non-frigerated baskets, along with a nice sign saying that it's ok to not change your mind.

They charge the credit card you gave them when you checked in.

Meh, cheap rfid, or funny barcode positionning to ensure their sensors can always track stuff. I'm not that thrilled, somehow I'm not in love with todays tech and progress (that's on me). Moreover I wonder what people living on cashier jobs (it's an easy target for unqualified and hurried people) will feel. Goodbye profession.

All the supermarkets I use already push you to self check-out stations....

True, but these often require one or two hosts to unlock issues.

I was for the test but I find the self checkout annoying. It's less efficient than the usual kind. You have less space to unload you stuff; less space to rebag them, and the cashier is lighting fast at scanning and grabbing the money because of 7h/day of doing so. I'm not pro human cashier, I don't think lots of cashier really like it either. But self checkout is not as good as I thought.

Not as crazy as it sounds. With RAIN Rfid you can get the xyz location of a tag from ~30ft away accurate to 6" in realtime. Examples: https://www.youtube.com/watch?v=p1LykdRWTfk https://www.youtube.com/watch?v=-hCA8L7v-R8

Also, since the app is still on your phone there is no reason they can't be using it to gather data as well.

They did say sensor fusion. I'm not sure if they have indoor location tracking in the app but it seems reasonable.

How about just not shopping at Wal-Mart? I stopped shopping there in 2009. When I returned to the US, I stopped shopping at Amazon because it had pretty much become the new Wal-Mart; maybe worse even. This is cool tech and I'd want to try it, but I hate shopping anything Amazon. They had sd cards at their brick and mortar store, but I decided to buy one at Office Depot instead, even though it was $10 more.

Upvoted for sensibility. in many rural areas of the United States, it is literally impossible to shop anywhere but Wal-Mart. Nebraska and Kansas had a rather large economic dive in the early 2000's due to the expansion of the Waltons. Their business plan is essentially: 1) Announce intention to move into area 2) woo politicians for financial kickbacks to subsidize expansion 3) launch with prices _far_ lower than all…

Isn't that illegal?

> When you walk out, the items are recognized and tallied by a large RFID sweep. But the video clearly shows the items being recognized as someone takes them from a shelf (and puts them back). The items don't need to be recognized at the time you walk out, the store just needs to know that you've walked out.

You mean that floating list in the air? I think that's just visually giving you an idea of what's happening. Like I said earlier, I'm giving a simple naive presentation of how the system might work. Or, at the least, how I would design it without dealing with finicky shelf sensors. Ask anyone that has ever worked in a hotel with in-room minibars how well those things pan out in real life. Unless that store is just a…

Agree with you, would be much easier to just checkout once when you leave.

The video makes it look like it's constantly up to date, but that sounds quite complicated (despite dropping the ML, DL buzz words).
