Developed by Sequestim and scientists from Cardiff University, the walkthrough scanner uses space technology to image human body heat.

Leveraging the computer learning, the scanner can differentiate between threats and non-threats without requiring the passengers to stop or remove outer clothing.

In addition, the scanner is capable of swiftly learning the difference between items that can and cannot be taken onto an aircraft, reducing the risk of false alarms that trouble passengers and decelerates screening.

The machine can also slash passengers’ queues at airport terminals, while positively affecting the effectiveness of security and help keep passengers safe.

“Passengers walking normally through security would no longer need to take off coats and jackets, or remove personal items such as phones.”

Sequestim sales and marketing director Ken Wood said: “Passenger numbers are expected to double in 20 years, putting airport security facilities under immense pressure.

“Our scanner combines a number of world-leading technologies developed by our team here in the UK. It uses the human body as a source of ‘light’, in contrast with existing scanners, which process reflected and scattered millimetre-waves while the passenger is required to strike a pose.

“Our system only needs a few seconds to do its work. Passengers walking normally through security would no longer need to take off coats and jackets, or remove personal items such as phones.”

Participation by passengers in the trial is by invitation only. It will be conducted from 4-7 December at Cardiff Airport without interfering with passenger journeys.
