StealthCo, Inc., an Oak Ridge, Tenn.-based firm doing business as Stealth Mark, has exclusively licensed an invisible micro-taggant from the Department of Energy’s Oak Ridge National Laboratory. The anticounterfeiting technology features a novel materials coding system that uses an infrared marker for identification.
