Airline passengers are using their iPhones and BlackBerries as their boarding pass at nine airports around the United States.
The federal pilot program started at Cleveland’s Hopkins International Airport on Thursday.
Instead of a paper ticket, passengers can download their boarding passes to their cell phone from their airline’s website.
The electronic pass includes a bar code with encrypted flight information and passenger identification. Security and airline officials then scan the pass at the airport.
Continental, Northwest, Delta and Alaska airlines are taking part in the program.
Transportation Security Administration spokesman Jon Allen says officials hope to add more airports within the next year.
