Someone cares to explain the technology behind this?

1. Scan your personal barcode with your phone when you walk in. Camera associates your physical self with your code.

2. Cameras track every item you pick up.

3. Cameras note when you leave the store and charge you.

I don't think the system works like that. From my first quick take of the video, the app+turnstyle is used to identify you to the store. The video system then tracks your position as you walk around. When you walk out, the items are recognized and tallied by a large RFID sweep. Funneling you back out through a turnstyle makes sure the vision system knows it's you. Notice that you don't need to barcode yourself on the…

> 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 mockup and not how it really looks and works, I see nothing on those shelves or in the sky above it that is watching you put that cupcake back on the shelf.

The real way to find out is if someone in the demo video can pull their phone out of their pocket mid-trip and see their current inventory and total price. But I didn't see that in the video.

The girl in the video at 1:26 looks at her list and total, but after she's been through the exit turnstyle.

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?

I'm assuming your Amazon Go account is tied to a credit card. In which case, it's not Amazon's problem. They got their money - you now owe your credit card company.

And if your credit card company declines the charges when Amazon attempts to bill them? Then they're out inventory and don't have any compensation. Then it becomes their problem.

I agree with your point, but at the same time, you should be charged the price of the food if you grab perishable food and place it in an area that renders it unsafe. I worked in retail and at theme parks, and I'm personally of the opinion that it's better for everyone in the long run if you fire entitled customers.

, you should be charged the price of the food if you grab perishable food and place it in an area that renders it unsafe That'd constitute a massive retooling of consumer behavior and logic and would require quite a bit of conditioning over many years, no?

That sounds like exactly what Amazon are trying!

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…

How it works sections aren't designed for the technically inclined user they are designed for the layman.

I know this is fairly impossible in urban areas but I find myself shopping much more frequently in what I call grocery farms. If you live in affluent suburbias I'm sure you have seen them. They are basically high end grocery stores that sells the produce they grow along with other things they buy from other local farms. Some of the produce is grown inside and seasonal things are grown outside. Yeah some of them are j…

> You say that like if it's a bad thing, you might want to better inform yourself on GMOs as there are A LOT of myths and misconceptions out there.

And you might not want to assume what I know and don't :)

I say it because GMOs are not open source. Local farms don't get access to GMOs and it can create an unfair advantage to big farms.

As for health reasons I don't believe that GMOs are bad for you but they may have lower nutrients since you can now grow on the same plot of land over and over (and soil depletion of nutrients is a real thing) [1].

I'll assume you didn't know about soil depletion... as there are lot of people that don't and you know its better to inform yourself :)

That being said I do agree that GMOs get mostly unfair sentiment.

> With our Just Walk Out Shopping experience, simply use the Amazon Go app to enter the store, take the products you want, and go! No lines, no checkout. (No, seriously.) Yes, seems like you check-in with an app.

I saw that, but it sounds vague enough that there a few different scenarios I can think of to attack this service. Like what are they going to do if multiple people are sharing an account, but they only have photos of one? edit: I just realized how they can deal with that -- take a picture when the person walks in and tie it to the account they scanned. There still seem to be a bunch of fraud issues, but this is cert…

They don't need to remember photos at all. Just track the person beginning at the point of scan.

What happens if someone sneaks into the store without an amazon account and walks right the hell out with whatever they want? Not a criticism, just curious what we speculate the theft prevention systems used here might be.

> What happens if someone sneaks into the store without an amazon account and walks right the hell out with whatever they want?

This is also a perennial concern at any tradition grocery store as well. Presumably, in a system that operates primary off of computer vision, you would:

A) Be able to quickly detect an unrecognized person in the store and alert security, and

B) Have very good video evidence of the person committing the shop-lifting to provide to police.

It sounds like they actually end up in a better position relative to a tradition grocery store from a security perspective.
