Armark Authentication Technologies offers covert markers that can contain multiple layers of information, including text, in a particle smaller than the diameter of a human hair. These markers are specific to a customer, so they can be seamlessly integrated into existing processes. Some examples of delivery methods include inks, overprint varnishes, papers, adhesives and films. The company also offers detection systems that identify these unique markers. Tamper-evident label stock that, once applied, is destructive upon removal to indicate product surety, is also available.
