After three years of little movement, the plan to furnish transportation workers with biometric ID cards is suddenly on the fast track, Washington Technology reported. The Homeland Security Department in May will solicit proposals for widespread deployment and make an award in July. But concerns remain about how the program, known as the Transportation Workers Identification Credential, will be funded and structured. Several large federal contractors, including BearingPoint of McLean, Va. and Lockheed Martin Corp., have confirmed they are interested in bidding for the fourth phase of the contract, which is production and deployment of cards for 850,000 port workers nationwide.
