QRSciences inks $33m agreement with US security company

Perth-based security technology group QRSciences Ltd has reached a preferred pricing and licensing rights agreement with US company, Rapiscan Systems, for QRSciences developed technology.

The agreement covers the co-developed Rapiscan QXR1000 baggage and package screening system.

Under the terms of the agreement Rapiscan will maintain preferred pricing and licensing rights provided it places minimum orders in each of the next 4 years which in aggregate totals approximately $33 million.

QRSciences chief executive Kevin Russeth said he was pleased to be working closely with one of the world's largest suppliers of security screening systems.

"This agreement brings Rapiscan's worldwide marketing, manufacturing and distribution power to bear for our first product and is another major step forward in the growth of our company. This success results directly from the extensive product testing and evaluation completed by the U.S. Department of Homeland Security, through the Transportation Security Laboratory, and also from Rapiscan's initial marketing outreach," he said.

The QXR1000 product was jointly developed by QRSciences and Rapiscan funded in part by a grant from the U.S. Department of Homeland Security's Technical Support Working Group.

The device combines QRSciences' technology with Rapiscan's most widely deployed 520B X-ray unit. It provides a comprehensive explosives and weapons detection solution for applications including baggage screening at airport checkpoints, public transportation facilities, high security buildings and other critical infrastructure.

The QXR1000 recently completed evaluation testing with the U.S. Department of Homeland Security and will be showcased and demonstrated to a range of Federal Agencies at Technical Support Working Group Explosives Detection Conference in the United States in June.
