Cellphones to replace boarding passes?

In a three-month pilot program at Houston Intercontinental Airport, passengers will be able to board flights using only a cellphone or a personal digital assistant instead of a boarding pass.

Passengers boarding Continental flights will show a code on their screen that has been sent to their phone or PDA. A bar code stores the passenger’s name and flight information, and a TSA screener will confirm the bar code’s authenticity by scanning it with a special handheld device. Passengers will still need to show photo ID.

Air Canada has also been offering this service since September, and reports that “passengers love the new service.”
