The International Air Transport Association (IATA) has announced a global standard for mobile phone check-in using 2d bar codes. The IATA standard will use the existing codes Aztec, Datamatrix and QR.
Mobile phone check-in enables airlines to send 2d bar codes directly to a passenger’s mobile phone, personal digital assistant or smart phone. Passengers simply register their mobile number with their airline at the time of booking to receive a text message with a 2d bar code, or instructions to download it. The bar code becomes the passenger’s boarding pass and it is read directly from the screen of the mobile device, eliminating paper completely from the check-in process.
IATA has set a deadline of the end of 2010 to implement 100% bar coded boarding passes (BCBP).
