So, I'm new to all this but found a tutorial on the darkweb about "Tagging" which is basically a slightly more advanced version of barcode switching where you're looking up the UPC for a product beforehand and printing out the barcode on a shipping label to tag on the item you want to scan beforehand and then running it through self-checkout with the label you printed of a much lower priced item...in other words it saves you the hassle of taking the barcode off another item first. So it seemed simple and foolproof enough to try as long as the walmart doesn't have anyone checking receipts which the one i usually go to doesn't.
My accomplice and I decide to try it. Now, I knew it'd probably be best to use some tricks like one of us tagging it a day or two prior to the other buying it and of course going to one in a completely different area from where I usually shop, but I got cocky and figured we'd get away with it at least the first time without going through that. So, we go there on a day I don't normally go on, but as usual there's no one at the exit checking receipts so I figured it's go time. We put the item in our cart which is a bigger box item. Then we go get some other items we intended to actually pay for, and then we went to the craft section where I learned there are no visible cameras from a previous scope out and placed the barcode on it. We go through checkout and ring it all up which goes fine, but now there happens to be an 80 year old lady at the exit checking receipts. She stops us to check our receipt which was a hiccup I was not expecting at all. Since they could easily figure out my real identity because I went to the one I normally shop at like a dumbass I decided to cooperate. I used walmart pay so we showed her that and of course she saw all the items but the large one and we acted like we weren't sure why it wasn't on there and said we did notice it rang up weird. I then lose the receipt off the app and pretend I don't know how to bring it back up on my phone. She leaves us at the door to go talk to the self-checkout people who don't know how to help her, and then she takes us to the customer service person to try to pull up the receipt, but she's busy and doesn't want to deal with it without us getting in a long line. We act like we don't have time to deal with it and just dumped the large item there and left. No one followed us or tried to stop us. Anyways, my question is do you think they had hidden cameras that saw us place the barcode on, or were we just suspicious, or were we just the victims of unfortunate timing since maybe they always have a person there at that time and I just didn't know that?
Things I learned.....I won't be going to that walmart for quite a while now lol. Also, no matter how foolproof a method seems don't get too confident and skip some basic steps like not shitting where you eat! Also, I won't be trying it again without having a fake receipt ready beforehand.
