Government agencies and security printers worldwide demand robust anti-counterfeiting measures for passports, ID cards, and other official documents. Nanografi’s specialized security inks—including UV/IR, thermochromic, electrochromic, and fluorescent formulations—integrate seamlessly into passport pages, ePassport chips, and visa labels. By incorporating DNA markers, IR markers, and graphene-enhanced threads or holograms, these documents gain multiple layers of tamper-evident security. Such measures ensure rapid authenticity checks, reduce fraud, and uphold national security standards.
