"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 last night sparked fresh concerns from privacy campaigners about the growing use of 'invasive' techology in the nation's shops.
"... Nick Pickles of Big Brother Watch said camera technology was already available that matches scans of people's faces when they walk into a shop with their pictures on Facebook, to tailor special offers to their 'likes' on the social media website."
