CAG Aviation Security vice-president Alan Tan said: "At Changi Airport, we take safety and security seriously and are committed to maintaining the highest standards."

New computed tomography (CT) security screening equipment is being used to check hand luggage at boarding gates.

The CT technology allows passengers to keep electronic devices in their hand luggage during the screening process, rather than placing them on a separate tray.

CAG will also test a new system that provides trays to two passengers at the same time, allowing them to drop off their bags simultaneously.

After the screening cycle has been completed, the trays will automatically be returned to the line, thereby removing the need to manually place the trays back at the start of the screening belt.

Hand luggage requiring further checks will be automatically sent to a separate channel for follow-up by security officers.

The new service will enhance screening efficiency and reduce waiting times for passengers.

"The data and passenger feedback we collect from the trials will help us assess the effectiveness and operational efficiencies of these new systems."

Tan added: "The data and passenger feedback we collect from the trials will help us assess the effectiveness and operational efficiencies of these new systems, before we ascertain their suitability for implementation at the airport."

The airport group is also trialling a body scanner machine that uses millimetre wave technology to identify metallic and non-metallic items.

Travellers will walk into the machine and be scanned removing items from their pockets or on their body.

The data will be analysed by a computer algorithm. If a concealed object is detected, a non-invasive outline image showing the item’s location will be produced automatically.
