Nanotech produces nanotechnology based optical image reproduction processes for creating iridescent and scintillating imagery on documents and products which are visible to the naked eye. The images have overt and covert anti-counterfeiting and authentication capabilities. Potential uses include every application where holograms are currently used such as currency, legal documents, and retail branding. Nanotech's wholly owned US subsidiary, Tactical Technologies Inc. designs and sells sophisticated communication surveillance and intelligence gathering equipment for use by US law enforcement agencies.
