How Advanced Technology Is Combating Passport Counterfeiting

A passport is an important document that other countries use to recognize you. As an overseas personal identity document, its security is of paramount importance.

However, some criminals use various tricks to make fake passports and carry out illegal activities. This poses a huge threat to personal and national security.

Therefore, passports must incorporate various innovative technologies to prevent criminals from using them to engage in illegal activities.

So how do advanced technologies protect your passports from fraud? Today, we will take you to learn about some interesting anti-counterfeiting technologies on passports.

Fluorescent Ink Printing(fluorescent fiber line)

It is a “hidden” design on the data page of the passport and is only visible under ultraviolet light. In the picture below, you can see the yellow-blue fluorescent fiber lines printed on the passport page. Nothing can be seen under normal light, but the fiber lines and numbers are clearly visible under UV light.

Hologram Image Protection

Statistics show that the United Nations was the first issuing agency to print holographic images on passports, and other countries soon followed. Add a holographic transfer overlay to the passport personal data page to ensure the data page is fully protected.

As a part of personal information, holographic images will not be lifted up or removed, and it is difficult to be tampered with. Its application reduces the possibility of passport fraud to a certain extent.

Since the passport is in the form of a book, the film applied to the passport is also called the book-type transfer overlay. The principle is that open print well pages of personal info manually, some country’s Regional public security organizations have auto machines to open the individual pages.

Then put book-type documents into the hot-pressing transmission equipment, so the film and book certificate individual pages are laminated together, finally peel off the raw clear film. The finished form is a single sheet of protective film.

Book type hologram heat transfer overlay, PET as a carrier, with multiple layers resin material, one side is customized micro-nano optical security pattern, the other side (outer) with hot-melt glue.

Documents and security film were bonded, then PET film was released, transferring hologram security pattern on documents under high temperature. Mostly used for passports, seafarers’ certificates, etc to prevent personalized information from tampering.

Structure Graphic of Book Type Hologram Transfer Overlay

In order to further enhance the anti-counterfeiting performance, a variety of security elements are designed on the film, such as zero-level light diffraction, optical guilloche, micro graphics, information fiber, and so on.

Optical guilloche is composed of dynamic and colorful thin lines with a width of 0.1m m-0.3mm. Gently turn the passport to see rich curves and colors. It is easy to identify with the naked eye, and there is a certain technical threshold for imitation. Micro graphics are well concealed and need to be identified with an 80-100 times magnifying glass.

These overt and covert security features applied to passports can overcome common threats such as passport forgery and tampering, making passports easier to identify or virtually impossible to replicate.

As counterfeiters continue to improve their counterfeiting skills, and the market demand for advanced anti-counterfeiting technology continues to grow, it is vital that our passport security evolves and progresses to stay one step ahead.
