Supermarket giant Tesco is installing hundreds of hi-tech screens that scan the faces of shoppers as they queue at the till to detect their age and sex for advertisers. The store giant has signed a ground-breaking deal with Lord Alan Sugar's Amscreen in a move which tonight sparked fresh concerns from privacy campaigners about the growing use of "invasive" technology in the nation's shops.
The 'OptimEyes' system will be rolled out into 450 Tesco petrol forecourts, which serve millions of customers a week.
