London: Clockwork Orange

Skip the queue. Just in time for the 4th of July and the summer rush, the UK has launched the new IRIS immigration service. Frequent UK travelers can now register for free at Heathrow terminals 2 and 4. The system will be rolled out at all UK airports soon. After having your retinas scanned upon entry into the UK, "enrolled passengers will be able to enter . . . through a special automated immigration control barrier incorporating an iris recognition camera. The barrier will be located in the Immigration Arrivals Hall and will form part of Immigration and Passport Control."
