Walmart SC

Submitted by DapperDan in Illegalism

So I was in what I would describe a high theft area.I was doing a legit purchase at the self checkout.After scanning a small pack of nitrile gloves from the auto section,a alert popped up.Visually inspect merchandise or something to that effect.The associate had to come over and type in her password and I was good to go.The only thing I could think of was the ol barcode switch.Anyone seen this before?

Yeah, they’ve got cameras above the self check. They run some sort of shrink reduction software (https://www.stoplift.com/) that can verify the thing that you’re scanning matches the upc label or something. I’ve had it go off on me when doing legit shopping at Walmart. The one I go to will actually play a loop of you scanning whatever it was, until the rep turns it off.

Of course they've got cameras above the self check. They've got cameras everywhere. What does that have to do with detecting scanning failure?

The link you provided just leads to an advertisement trailer from the company that's selling this "shrink reduction software", whatever it is. All it shows is an overhead camera and some footage of customers self-scanning items. It doesn't explain how the detection process works, so i'm inclined to think it's a lot of hype, designed to sell a piece of camera. And this is just an ad. It doesn't prove that any stores have bought what it's trying to sell.

Just how exactly would they detect scanning failure? Go on, somebody explain it to me. I think I'd be perfectly capable of understanding.

To my knowledge, the best tool stores have at self check out right now is the bagging area scale. When you scan an item, the screen will ask you to place item in the bagging area, and will not let you scan any more items until you've done that. The item gets weighed on the bagging area and the weight is compared to the weight of the item on file for the UPC code just scanned. If the weights don't match, you get "locked out" of further scanning until a sales associate unlocks you. That's it! Except many stores have the "skip bagging" option, where you get out of the requirement to drop scanned items onto the bagging area.

Stoplift is an AI powered software that has detection abilities built in to the SCO, and the overhead camera. So if you try to pass an item straight to a bag without scanning or you scan a cheaper item and try to bag a different more expensive item it will lock out the register and queue a video clip of what happened for the SCO host to review what happened before they override it and allow the transaction to continue.

It's very effective at reducing SCO fraud/theft. Alot of people have been busted in my vicinity because of it. A tip is if you use the handheld scanner to scan items in the cart or away from the register top itself it can't "see" that. So if I'm at one of the stores that uses this tech I will do that.

This does not cover the most common case: when someone just pretends to scan an item by running it over the scanner, but in reality is covering the barcode with the hand. Or when you have two items of the same kind, stacked one on top of the other, and you're just scanning one of them and dropping both in your own reusable bag, after hitting the "Skip bagging" option.

It also does not cover the case when someone is using big items in the cart to cover smaller items underneath it. Far from the claims made in the video, this AI software is a crude tool at best.

More to my point though, the ad video in the original link made absurd claims, such as "Get paid for every item, every time". Really? Who do they expect to fall for THAT? Retailers want to reduce labor cost and reduce SOME of the theft, but everyone knows that theft WILL happen no matter what. Getting paid for every item is just a sh!tty pipe dream.

Everything you mention the SCO host could see. Now they carry a PDA that they can pull up the item list for each SCO. In addition to the POS terminal that displays all of them in real time.

Point is there are checks in place. I'm simply trying to educate here. No need for hostility.

Thanks for explaining all that better than I could. I’m not even 100% sure that stoplift was the program that Walmart uses for sure. I got dinged by it one day, and remembered the article you posted below. Stoplift was the first thing I found when I googled it.

I have no doubt there are checks in place. I'm not disputing that.

At the same time, if you're trying to tell me that there is software that can detect 100% of all the fraud at self check out, then you're being as absurd as the video ad makers who claim the retailer will "Get paid for every item, every time." If I was a retailer I wouldn't buy any product from this company. It's clear they're playing on retailers' desperation and wishes in order to sell them a product. They may as well claim to sell you a winning powerball lottery ticket.

"Walmart ai camera computer vision tracking theft" … buzz words and sound byte.

I don't need a google search. It still wouldn't answer my question. Video ads and news media articles aren't meant to do that. They have other purposes.
