Tesco has introduced VAR-style replay technology at its self-checkout tills to combat shoplifting. The technology uses artificial intelligence to detect when items may not have been properly scanned. If a shopper fails to scan the items correctly, they are warned to remove from the bagging area and try again. Retail experts believe this visual evidence makes shoplifters more likely to pay for items rather than risk being caught. The technology could lead to the removal of security measures from everyday products. Shoplifting has reached record levels in the UK, costing retailers £2bn annually, and staff facing increasing violence and abuse.
