Smiths Detection, a provider of threat detection and security screening technologies, has secured a contract of more than $4m from the Transportation Security Administration (TSA) for the supply of IONSCAN 500 DT Explosives Trace Detection Systems (ETD) to airports across the US over the next two years.

The contract includes on-site service maintenance.

The new ETDs are in addition to the systems that are already installed at various airports for secondary screening at checked baggage areas or checkpoints.

IONSCAN 500DT, certified on the TSA Qualified Products List for security screening, uses ion mobility spectroscopy (IMS) to trace explosives in seconds.

It is easy to use, enabling the operators to detect a wide range of military, homemade and commercial threats.

Deployment of additional Smiths Detection ETDs will allow airports to maintain screening efficiency.

Smiths Detection president Shan Hood said: “Our mission is to make the world a safer place by providing our customers with the most advanced detection technologies. We aim to help safeguard society, protect life and support the free flow of trade. We are proud to be Smiths, pushing boundaries to deliver innovative solutions for the world’s challenges.”

In November, TSA at Daytona Beach International Airport (DAB) in Florida started using an advanced computed tomography (CT) scanner at its security checkpoint.

Due to the use of CT, passengers can refrain from removing electronics, food or travel-size liquids from their carry-on luggage.

During the same month, Delta Air Lines and TSA partnered to launch the first curb-to-gate facial recognition option using a digital ID for US domestic travellers at Detroit Metropolitan Wayne County Airport, where participation is entirely voluntary.
