Government agencies and security printers worldwide require advanced anti-counterfeiting solutions for passports, ID cards, and other official documents. NanoChicago provides specialized security inks—such as UV/IR, thermochromic, electrochromic, and fluorescent formulations—that can be seamlessly integrated into passport pages, ePassport chips, and visa labels. By adding DNA markers, IR markers, and graphene-enhanced threads or holograms, these documents are equipped with multiple layers of tamper-evident security. These measures enable quick authenticity verification, reduce fraud, and ensure compliance with national security standards.
