Paperless boarding passes for smartphones hit SFO
San Francisco International Airport (SFO) is the Bay Area's first airport to employ a secure barcode-scanning system for paperless boarding passes so travelers with Internet-connected smartphones, like BlackBerrys and iPhones, can check-in using their handhelds. The system, which is currently being used on an experimental-basis, has the potential to save airlines money on printing costs and reduce paper-waste, as well as relieve potential stresses to travelers of misplacing boarding passes.
