Researchers at Lancaster University’s tech startup Quantum Base are working on a graphene-based identity tag that can be scanned using a smartphone, to provide a possible solution to the fake goods problem that is causing worldwide financial damage on a grand scale.
The researchers have designed a tag that can be verified by the end user using a smartphone. While other authenticity identifiers exist, like holograms, security inks and chemical or physical markers, this new system relies on graphene to make it unique. The team explains that the 2D nature of graphene means that even the tiniest imperfections, caused by the smallest of changes in the structure of an atom, can be identified. It also makes replicating the tag hard for fraudsters, if not impossible. The patented technology is expected to be available to the public next year.
courage,inca.
