The Transportation Security Administration (TSA) and Continental Airlines have begun a paperless boarding pass pilot programme at Luis Munoz Marin International Airport (SJU) in Puerto Rico.
Under the new programme, passengers will be able to receive boarding passes electronically on their cell phones or PDAs, which will then be scanned by transportation security officers at the checkpoint.
Paperless boarding passes will display an encrypted two-dimensional bar code along with passenger and flight information. TSA travel document checkers will then validate the authenticity of Continental passengers' boarding passes.
The new technology is designed to strengthen detection of fraudulent boarding passes, improve customer service and reduce paper use.
The pilot programme has been designed in compliance with International Air Transport Association (IATA) guidelines for the bar coding of passenger boarding passes.
