What Are the Security Enhancements Offered by Nanotechnology?
Nanotechnology provides several ways to enhance security during the visa application process. For instance, _nano-coatings_ can be applied to passport materials to make them more resistant to tampering and forgery. Additionally, _nano-ink_ can be used to print invisible watermarks that are only detectable with specialized equipment, making it extremely difficult for counterfeiters to replicate official documents.
