McLEAN, Virginia, June 22 -- EyeTicket Corp. and Unisys Corp. jointly announced a new strategic marketing alliance under which Unisys will offer the EyeTicket passenger processing system to its customers. EyeTicket passenger processing systems use iris recognition technology to quickly identify passengers and expedite all steps in the airline passenger processing sequence. The two companies signed a Memorandum of Understanding defining the principal business terms of the alliance, which has an initial term of two years. The agreement provides that Unisys only offer EyeTicket systems to Unisys customers seeking iris recognition-based systems for ticketing, check-in, baggage check, baggage identification and boarding in all airport and airline applications for commercial aircraft passengers. The alliance will provide further optional marketing opportunities for each company. Unisys is authorized to offer EyeTicket products for other applications as desired, and EyeTicket can take advantage of Unisys installation and support services as desired for its worldwide projects. John Daugman, PhD, of Cambridge University in England, pioneered Iris recognition technology. The technology examines more than 240 degrees of freedom in the human iris to create the patented IrisCode record, a 512-byte data template used to identify individuals and/or authenticate user privileges. Iris recognition technology is the most accurate, scalable, stable, fast and noninvasive biometric technology in the world.
