Changi Airport Group conducting new security screening technology trials

Singapore

CHANGI Airport Group (CAG) is conducting two-month trials on new security screening technologies which include an enhanced body-scanning machine that uses millimetre wave technology to detect both metallic and non-metallic items. This is an improvement over the walk-through metal detectors currently used for departing passengers.

After removing items in their pockets, passengers simply need to walk into the body scanner and be scanned - a process that takes a few seconds. The data is analysed by a computer algorithm. If a concealed item is detected, a non-invasive outline image indicating the item's location will be generated automatically, allowing security officers to zoom in on the identified area to check the item. If nothing is detected, a green screen with an "OK" appears and the passenger clears quickly.
