CLEAR, the biometric identification program that allows travelers to speed through security lines, has been revived. Passengers flying through Denver International Airport and Orlando International Airport now can show their CLEARcard to a CLEAR attendant, verify their identity by their fingerprints or iris image, and step through to the TSA screening. The program had been shut down in June 2009, and has been relaunched by new owners Alclear LLC. Membership is $179 a year for unlimited use; a family plan adds a second household member for $50. Children use the CLEAR lane free when accompanied by an adult member. For people who already had CLEARcards when the service shut down, the company will honor membership terms that remained as of June 2009.
