Laser Surface Authentication System

Laser Surface Authentication System main

Despite our niftiest holograms and watermarks, counterfeiters still manage to sneak billions of dollars of fake goods onto store shelves. Instead of slapping on authenticity seals, which can be copied, Ingenia Technology’s anti-counterfeit scanner reads the nanoscopic variations that occur naturally on the surface of every object, from documents to a perfume bottle, and no two are ever the same. To do this, laser light strikes the object, and detectors measure the random scattering of photons that bounce back. The system still recognizes the original nanostructures on a sheet of paper even after it has been baked, soaked, scrubbed, crumpled, and scribbled on with a pen. ingeniatechnology.com
