Patch Security Overlay – Surface Protection for Card-Type ID Documents

What Is a Patch Security Overlay for Cards?

Our patch security overlay, also called surface patch, is a thermal lamination film specifically designed for card-type identity documents — including national ID cards, driver’s licenses, and employee access badges.

The patch is thermally laminated directly onto the card substrate after personalization, creating a protective security layer on the document surface.

How Does Our Patch Overlay Work?

After personalized information is printed onto the card substrate, our surface patch is thermally bonded to the document.

The final security film lies permanently on the surface of the identity document, protecting printed data from wear, chemical exposure, and physical tampering.

What Security Features Are Embedded in the Patch?

Each patch security overlay incorporates a DOVID (Diffractive Optically Variable Image Device) — a diffraction-based security feature implemented on plastic substrates for government-issued identity cards and driver’s licenses.

What Security Levels Can We Provide?

Our patch overlays support all three security levels:

• Level 1 (Overt) – Public-facing holographic effects
• Level 2 (Covert) – Hidden UV or microtext features
• Level 3 (Forensic) – Laboratory authentication

Why Choose Our Patch Security Overlay?

We provide end-to-end design and technical support for optical security solutions. Our innovative designs and materials help you minimize counterfeiting risks.

We customize every patch based on your country or city’s cultural identity, official marks, or symbols. All production complies with ICAO and international security standards.

What DOVID Effects Are Available for Patches?

Our DOVID technology produces:

• Dynamic chromatic and color-shifting effects
• Holographic 2D/3D imagery
• Kinematic motion patterns
• Diffraction gratings with micro-/nano-structures

These visual effects are instantly recognizable by the human eye yet virtually impossible to replicate, ensuring robust protection for personal data.
