Guam - If you're traveling Continental, all you have to do is pick up your mobile phone or PDA and voila - you've got your boarding pass! This morning the airlines made the mobile service available to Guam customers. Continental Airlines Senior Analyst Ann Santos Santo Tomas says the new technology heightens the ability to detect fraudulent boarding passes while improving customer service and reducing paper use.

"The type of barcode that we use is a 2-D Aztec barcode and the reason why this barcode was used is because it's proven to be one of the most secure barcodes out there. We found that if it's manipulated in any way it becomes corrupt, and it's no longer valid so if you try to manipulate that barcode in anyway then and scan it, you won't get a valid scan," he said.

The airline currently has 49 airports using mobile boarding passes, and is considering bringing the system to the CNMI.
