TSA seeking shoe scanning system

According to the Office of Federal Business Opportunities, the Transportation Security Administration is soliciting bids for a new shoe scanning system.

The listing, which was posted last week on the FBO’s website, says that the Shoe Scanning Device (SSD) System needs to be "capable of detecting threat objects concealed in footwear without requiring passengers to remove their footwear as they pass through a security checkpoint."

The TSA has made travelers remove their shoes since shoe bomber Richard Reid attempted to blow up a U.S.-bound flight by igniting explosives concealed in his shoes in late 2001.

Department of Homeland Security Secretary Janet Napolitano said last week that the agency was working on developing new technologies that would reduce the need for physical searches of passengers.
