Hand luggage check system allows laptop to stay in the bag

If tests at Singapore Changi Airport prove to be successful, travellers may be allowed to leave their phones and laptop inside their bags during security checks in the future. Trials of advanced 3D screening technology are currently being performed at the airport.

Until now, passengers have to take electronic devices such as laptops and tablets from their hand-carry luggage and place them on a separate tray for screening. If the new computed tomography (CT) security screening technology works well, passengers only need to remove items from their pockets and can then simply walk into a body scanner; scanning takes a few seconds.

The new enhanced body scanning equipment uses millimetre wave technology to detect both metallic and non-metallic items. The system utilises a very low-power non-ionising form of electromagnetic technology. The amount of electromagnetic radiation emitted by millimetre wave security scanners is many times smaller than that emitted by a mobile phone.
