"Airport security chiefs and efficiency geeks will be able to keep close tabs on airport passengers by tagging them with a high powered radio chip developed at the University of Central London. People will be told to wear radio tags round their necks when they get to the airport. The tag would notify a computer system of their identity and whereabouts. The system would then track their activities in the airport using a network of high definition cameras."
