Monash invents no-trays-required airport security scanner

written by Daniel Croft | October 25, 2022

Revolutionary new security checkpoint technology developed by Monash University is set to cut down long airport wait times and increase security.

The tech, which was created in conjunction with Australian X-ray business Micro-X, will allow passengers to be scanned with their belongings, removing the need to unpack them all onto a conveyer belt.

Further cutting down check-in times, the CT scanning system is much smaller than those currently found in airports, meaning more can be fit into the same space and more passengers can be scanned at once.

On top of cutting down wait times, the new system is also unmanned, reducing the amount of contact between individuals.


As a major player in the airport security technology space, Micro-X was granted a contract to develop and trial a self-screening security concept that would simplify the airport security scanning process.

“Security lanes are currently one of the biggest choke points at any airport,” said Micro-X.

“We are developing an unmanned self-service portal that combines scanning of personal effects and baggage with a passport reader and body scanner into one.

“By eliminating the need for high staffing to monitor baggage security, this X-ray system will transform airport security and increase efficiency — without compromising on safety.”

As lead design researcher at Monash University, Dr Nyein Chan Aung explained, the new system is less about the technology involved and more about creating an experience optimised for the traveller.

“This new system design reconsiders every element to serve the user, including the industrial design, floor plan layout, lighting, ergonomics, materials, and user interfaces,” he said.

“Undertaking a user-centred design approach is critical to the success of new technologies and ensuring that the workflows allow for optimal system performance while maintaining ease-of-use, convenience, and dignity for passengers from all walks of life.”

The new technology is not the only push of late to streamline the airport check-in and security process.

Air travel has seen a significant increase post-pandemic, resulting in longer wait times for those looking to check-in.

Avalon Airport in Victoria introduced ‘touchless’ check-in and bag drop kiosks and has moved to 100 per cent computed tomography technology that allows users to leave laptops in their bags during check-in.

Perth Airport has also announced that passengers on certain Singapore Airlines flights can now use facial recognition instead of boarding passes.
