LONDON: Britain's biggest retailer Tesco is to install screens at its petrol stations that scan customers' faces so that advertising can be tailored to their age and gender. 

The world's third biggest supermarket chain will install the high-tech screens at the tills of its 450 British petrol stations, according to Amscreen, the digital advertising firm that developed the technology.
