QRSciences Holdings Ltd says a contract with Australian Customs Service for work on an advanced weapon detection system will bring at least $2.5 million in sales revenue to the company over the next 18 months. The detection system will be used for international mail and package inspection and represents a new revenue stream for the company. ?Applying advanced metal detection to detect firearms in packages is a natural fit with our existing QR-based explosive detection,? QRSciences chief technology officer Timothy Rayner said. ?We believe our expertise in developing robust, highly sensitive detection systems is well-suited to address the needs of Australian Customs and other organisations interested in improving the detection of weapons within mail, packages and baggage. ?The technology should assist in detecting and intercepting attempted importation of illegal weapons and their components.? Mail packages and cargo entering Australia today are manually scanned using X-ray equipment. The new system will allow for automated detection assisting the operator in their decision making process. Development of the system has been funded in part by a $2.8 million federal government innovation grant.
