Two airports began scanning passengers’ eyes this week to help streamline boarding and security processes, using video cameras to scan the iris…EyeTicket began registering passengers at Charlotte/ Douglas International Airport in North Carolina and Flughafen Frankfurt Airport in Germany this week. The company has already been scanning Charlotte/Douglas airport employees and U.S. Airways Group Inc. flight staffs since May. The iris scans translate the 266 independent characteristics of the iris into a 512-byte digital code. A 30 frame per secong, black-and-white video camera is used to take a picture of the eye from 6 to 36 inches away. EyeTicket Chairman and CEO Stewart Mann says iris scans aren’t invasive like retina scans, which use a laser to probe the eye. He also said retinas change during a person’s life, whereas irises don’t.The airport rollouts are among the first major business applications involving iris-scan technology. Once U.S. Airways passengers enroll, their codes will be stored for future use, and Mann says he hopes airline passengers will be able to step in front of a terminal kiosk, get scanned in one second and then be issued a boarding pass - a process he expects to bring online within a year. www.eyeticket.com
