Substrate marking

OVDot™ particles can be incorporated in various substrates during the manufacturing process. These substrates include: security paper used for printing secure documents like banknotes, tax stamps and passports; various polymers used for manufacturing ID cards, payment cards and other secure items; and other substrates like glass or even high explosives. As with other applications, the presence of OVDot™ particles in these substrates will help to verify that the finished item is genuine (by using the security features of the particles) and to trace the substrate, and therefore the finished item, to a particular substrate manufacturer, printer or even a particular batch of product (by using the variable alphanumeric data on the particles).
