Charlotte Douglas International Airport in the US is installing Backscatter full-body scanners at checkpoints B and D, according to charlotteobserver.com.
The devices will use advanced imaging technology to detect metallic and non-metallic threats, including weapons and explosives hidden under a passenger's clothing.
The scanners project low-level X-ray beams over a passenger's body to create a reflection that will be examined by a TSA agent sitting at a distance from the scanner.
Passengers will have to remove their shoes and other items in their pockets to go through the scanners.
The TSA said it plans to install 450 full-body scanners in airports across the US by the end of this year and more than 500 scanners by next year.
