Basically i just want to know will the machine be able to tell i put a high cost item in the bagging area that just so happens to have a cheaper barcode? Specifically if the barcode is a sticker that was made in store, like if it was a $3 piece of cheese wrapped and tagged in that store, but i scanned a $15 steak? I assume they have to be similar enough in weights. And if so how much room for a weight difference can it be? Does the barcode tell the machine the exact weight so it knows exactly how much weight should have been added to the bagging area? there has to be a little bit of wiggle room there right?
how precise is that weight calculations for the baggage area?
not worried about stuff like boxes with a upc made by the manufacturer, specifically just stuff that is both tagged in that store.
same too, usually they walk right up and scan their card and punch in some numbers and walk away. they are almost always overwhelmed with shit going on cause those machines are so touchy and people still haven't figured out when and how to place things in the baggage area properly on top of just the machines being janky. there is 6-8 self checkouts in one store by me and one person is managing the whole thing so they don't seem to even have time to deal with anything else lol
