TSA Using Black Lights to Screen ID Cards
The Transportation Security Administration, which has taken over document-ticket screening at U.S. airports, is rolling out small black lights and loupes (magnifying lenses) to 1,300 specially trained screeners who check suspicious IDs in the ticket lines. Airline contractors did the preliminary driver's license checks at major airports until August. Until then, the TSA had no occasions in the security process to vet people's IDs against their boarding passes.
