Quote:Walmart has come up with an imaginative way to crack down on shoplifting at its self-checkouts.
The retailer has introduced a feature that lets shoppers simply move an item over the self-checkout scanner, which will register the item without needing to scan a visible bar code.
The new technology works on any Walmart Great Value branded items, such as graham crackers, chocolate bars and croissant sandwiches.
The invisible barcodes were first introduced to Walmart branded items in 2019, through the chain's partnership with Digimarc.
Digimarc Barcode's are invisible to the naked eye, but are printed all over an item enabling it to be easily picked up by a self-checkout scanner.
