Any plans to roll this out in the US?

"The September 11 hijacked plane attacks on the US have prompted London's Heathrow, one of the world's busiest airports, to install cameras that read a passenger's eyes to make identification foolproof. From next month, 2,000 North American frequent flyers on British Airways and Virgin Atlantic will check in and clear passport control simply by looking into an iris-scanning camera that can verify their identity in seconds. UK Customs, which is also involved in the project along with airport operator BAA and immigration authorities, would have access to a database to cross-reference the pictures of passengers. Iris scanning is considered almost error-proof as the chances of getting a matching pattern when comparing two images is as low as one in seven billion. While an infrared camera will be doing the checking, passengers will need to have their passports ready just in case."
