Amazon Ditches 'Just Walk Out' Checkouts at Its Grocery Stores (gizmodo.com) 161

Amazon is phasing out its checkout-less grocery stores with "Just Walk Out" technology. The company's senior vice president of grocery stores says they're moving away from Just Walk Out, which relied on cameras and sensors to track what people were leaving the store with. From a report: Just over half of Amazon Fresh stores are equipped with Just Walk Out. The technology allows customers to skip checkout altogether by scanning a QR code when they enter the store. Though it seemed completely automated, Just Walk Out relied on more than 1,000 people in India watching and labeling videos to ensure accurate checkouts. The cashiers were simply moved off-site, and they watched you as you shopped.

Instead, Amazon is moving towards Dash Carts, a scanner and screen are embedded in your shopping cart, allowing you to checkout as you shop. These offer a more reliable solution than Just Walk Out, whose impressive technology was truly ahead of its time. Amazon Fresh stores will also feature self check out counters from now on, for people who aren't Amazon members.

    >>whose impressive technology was truly ahead of its time

    Other than being done remotely, how exactly is hiring a human being to follow customers around and bill them for what they take "ahead of its time"? More like a throwback to the (very) old days of picking something off the shelf and telling the shopkeeper to "put it on my tab". The only "innovation" is the off-shoring of labor (which in this day and age is hardly innovative).

      Indeed, it's less "impressive technology ahead of its time" and more "nice idea ahead of the technology".

      They were likely counting on AI catching up quickly to avoid having that labor all together. Get the cost of AI mistakes down to less than the cost of labor and you win.

      Because it's not an accurate description of the process, is why (check the link they cite, though it's paywalled). It was not "remote human beings following customers around and billing them for what they take". It was an automated system, but because it was still in development and not yet trustworthy, they then had humans review every transaction to see if they agreed. In most cases, they did. In cases where they did not, this became training data for the automated system.

      It's unknown how reliable they ultimately got it, what the failure rate was. But the thing is, its competition - having users scan their own items as they put them into their cart - is probably no more expensive to implement, but still lets you offload all checkout labour (except surveillance for shoplifting) to customers themselves. Users lose out on convenience, but from a corporate perspective, it won out.

        With all the unknowns we don't know what went wrong, and Amazon probably won't tell us if they figured it out. I'm not surprised it didn't work well enough to continue. They may have wanted to attract more customers, and the more customers in the store, the harder tracking everybody becomes. And how many people got the creeps from having surveillance all over the place?

        Talking about versus a 'walk out with your groceries' or versus 'having to go through a cashier'?

        Technically speaking, self scan at the cart is a *tad* more work, but hardly worth mentioning. The same action you were doing to pick up the item takes a slight detour to get scanned.

        Compared to going through a cashier? That always sucked, there was nothing convenient about that. Self-checkout is significant improvement, but spreading that over the trip when you can take your time is more convenient than havin

    After checking out, the receipts took hours to be produced so I was wondering if they were being reviewed by humans. I seem to remember that Amazon Fresh said the system was automated but it's interesting to learn there were 1,000 people watching the cameras.

      • by cusco ( 717999 )

        You get an email thanking you for shopping, then a couple hours later the receipt arrives via email. Your card isn't charged until you've been sent the receipt. Originally the receipt arrived within half an hour, but then they opened more stores. I generally review the bill, and only once has it been in error (they charged me for one box of pasta instead of two).

    • Seems to me having to remember to check your receipt for accuracy hours later would be a big hassle. I'm guessing that was what Amazon was counting on, since most people aren't going to notice.

      That's like those mini POS terminals restaurants leave on the tables that calculate the tip on the post-tax amount, and then kind of shame you for not leaving at least 20%, by making that the default.

      • Restaurants and shops really should be required to include sales tax and labor in the sticker price instead of making the tax a fucking guessing game of "what jurisdiction is this and how many of which sales taxes am I paying?" and "You get to decide if the waiter gets to eat tonight or not, PWYW" dilemma. Sum it up FFS.

      Err no. Not an annoyance at all. This kind of shopping is common in my country and I've stopped shopping at grocery stores which don't offer it. Take an item off the shelf, scan it and put it in your basket, rinse, repeated, at checkout scan a barcode, pay and leave. Done. I typically complete the entire checkout process (there's never a queue either) in the time it takes for some normal guy to fumble around with his cash getting asked whether they want a receipt.

Our spirits are assaulted whenever we hear politicians hatefully brag about how they will create more jobs instead of leading us toward the Star Trekkian paradise of less soul-crushing or injurious toil.

    I thought Amazon was one of the few good guys, working to help create a world of 100% unemployment. I know it's only an ideal to strive for (we'll likely never free everyone from having to work) but they seemed to be trying.
