From Wireless Week IATA Creates Mobile Barcode Standard

The International Air Transport Association (IATA), a trade body that represents 240 airlines and 94% of scheduled international travel, has reached an agreement on a global standard for mobile barcodes, which it says "paves the way" for air travelers to use mobile phones for check-in at airports.
Regional formatting differences has slowed down the deployment of mobile applications, though several airlines have adopted mobile barcodes for check- bin, there has not been a unified solution.
The IATA solution uses existing codes: Aztec and Datamatrix, which are used extensively in Europe and North America; and QR which is widely used in Japan. All three are proven technologies and can be read by a single scanner type that is available globally.
The association said it hopes to use the standard to begin working with members to develop standardized processes and guidelines to "facilitate global implementation."
The industry has set end of 2010 as the deadline to implement 100% barcoded boarding passes. The association estimates that once boarding passes are 100% barcoded, the industry could save more than $500 million annually
