Here in Germany, it's common to weigh goods that are priced by weight and then have a sticker printed out to stick on them for the cashier. I don't see printing

  Interesting. I am skeptical that US consumers would have the discipline to do this. Maybe another way to solve this problem would be adding a weigh station next to each SKU (or group of SKUs), and then the station logs the weight in the app as the customer puts the item in their bag?

    Meijer (US megastore retailer that competes against Walmart in the American midwest, though generally has slightly higher prices and higher quality items) has introduced this recently with app-based self-checkout, and it's picking up adoption at a fairly quick pace. Another huge regional grocer, HEB, does this in Texas with their largest and most upscale stores, and it's been a norm for nearly a decade.

    That’s also common, in the self-checkout machines. Instead of scanning the barcode you just drop the item on the surface and select it on the screen.

      True, I didn’t consider that. I suppose it’s not that expensive to put scales everywhere.
      • sithadmin 7y ago
        Depends on the state in the US. Almost every state has relatively strict requirements regarding which models of scales may be used for trade (pricing), and some impose taxes and other fees to keep them in operation. Most scales on grocer floors that are accessible to customers (if you can even find them these days) are clearly marked as "not legal for trade" or have a similar disclaimer -- precisely because it would be too expensive to keep carefully calibrated trade-legal scales exposed to the general public.

          I had no idea this was a thing, but I’m glad that it is actually a thing.

          in nj, scales are inspected by the local Office of Weights and Measures. mis-calibrated scales can result in a fine for the grocer.

  That would still require you to scan something. You don't scan anything here - you just take what you want off the shelf and leave.

    What if the customer took the vegetable and put it in a bag which sits on a scale right in front of the shelf. Then they take the bag and go. Alternatively, the entire shelf is a scale, but the shelves are smaller so that only one person can pick vegetables at a time.
    • sithadmin 7y ago
      Forcing the customer to drop the item(s) on a scale seems most reasonable, but requires relatively strong controls to ensure the customer isn't pulling shenanigans like placing item A and item B into a bag, then co-mingling them when weighing them later.

  As long as you don’t have more than one person picking up produce from a bin at the same time you can just measure the change in weight from the bin it’s taken out of. That has to be super cheap technology at this point.
  • sithadmin 7y ago
    Seems complicated. Even if you're resetting tare on the bin regularly, fruits and vegetables can have significant changes in weight due to dehydration, and most markets are doing things like misting chilled produce with water, which will introduce constant and somewhat unpredictable changes in bin weight.

      The tare would be reset each time a customer picks something up. The total bin weight doesn’t matter, just the delta between before and after the computer vision system identifies that a customer removed some of the bin’s contents.

        >The tare would be reset each time a customer picks something up. This would run afoul of commerce laws in pretty much every US state. Tare must be set from zero, not relative to whatever happens to be on the scale, and certainly not on the fly.
