Gadgets: Biometric Testing for Workers on London Olympics Building Site

Gizmodo: "Over 100,000 construction workers on the 2012 Olympics venue in London will be subjected to biometric tests while they build the site. The two-tier system will scan hands and faces, and should be up and running by June this year, when work starts on the 50-acre site. And these measures, part of the $700 million security budget, will not just be for the building contractors, either."
