cultiv8 writes with this excerpt from an AP story as carried by Yahoo: "Eye scanners and futuristic security tunnels may be standard in airports soon as the airline industry seeks to maintain safety while reducing the hassles of boarding a plane that deter some people from flying. The International Air Transport Association unveiled a mock-up Tuesday in Singapore of what it dubbed the 'Checkpoint of the Future,' where passengers separated by security risk would walk through one of three high-tech, 20-foot-long (6.1-meters-long) tunnels that can quickly scan shoes and carry-on luggage and check for liquids and explosives. ... In the IATA prototype, passengers would be categorized based on the results of a government risk assessment that is put into a chip in a passenger's passport or other identification. An eye scan would then match the passenger to the passport."
