I don't understand this. You have a product with a UPC. You have a picker with a UPC and a scanner. If the scanner scans the wrong UPC, the picker grabbed the wrong thing.

More like I ordered spicy taco seasoning and receive regular taco seasoning. So a mistake that makes sense if you were matching on titles but why not match on UPCs?
