What Are Some Specific Nanotechnology-Based Features?
Several innovative features can be integrated into passports using nanotechnology:
Nanotextures: Unique textures at the nanoscale can be embedded into the passport pages, which are difficult to replicate without specialized equipment. Nano-inks: Special inks containing nanoparticles can be used for printing that changes color or visibility under different lighting conditions. Nano-watermarks: Watermarks with nanoscale details can be embedded within the passport pages, providing an additional layer of security. Nano-coatings: Coatings at the nanoscale can be applied to enhance durability and prevent tampering.
