Full-body scanning of passengers has begun at the Lambert-St. Louis International Airport in Missouri, US, in a bid to enhance passenger security at the facility.
The first device has been installed in Terminal 2 and the second device will go live on 12 October, while more devices are expected to be installed in the future.
The two new imaging devices will use low-level X-ray beams to screen passengers for metallic and non-metallic threats without any physical contact.
A black-and-white image is obtained once a passenger goes through the scanner, the image cannot be stored, printed or transmitted and will be deleted immediately by the Transportation Security Administration (TSA) officer who views it in a separate location.
Passengers who do not wish to go through the full-body scanner can opt for alternative screening, such as a physical pat-down.
The TSA has installed 259 of the units at 58 airports nationwide and will deploy 450 by the end of this year, according to stltoday.com.
