"THE annoyance of having to remove shoes during airport security checks is to become a thing of the past thanks to technology developed in Australia.Perth company QR Sciences has signed an agreement with US industrial giant General Electric to supply technology for a machine capable of scanning shoes. Travellers stand on a platform and GE's ShoeScanner uses the technology, which is similar to a medical MRI, to detect explosives within five to eight seconds. The technology uses radio waves to penetrate objects and excite a response from the atoms in substances such as plastic explosives. It is more sensitive and versatile than traditional detection techniques."
