The Millimeter Wave Unit is designed to be faster, harmless, more efficient and less invasive than a physical pat – down. The airport scanner costs up to $170,000 and is one of 560 in the nation.
The system uses a generic outline of a passenger. If a threat is detected, the screen highlights the area of the body requiring additional screening.
“If no anomaly is detected the word okay appears and the passenger is clear,” said Mark Heisey with the Transportation Safety Administration.
TSA experts say the millimeter wave technology can detect both metallic and non–metallic items.
The system does not store or print passenger information. The screen is cleared after each passenger.
