What it is
Laser engraving personalizes compatible polycarbonate layers by creating controlled marks within the card body rather than applying surface ink.
HOW IT WORKS
Technical principle
A laser interacts with sensitized layers inside a laminated polycarbonate construction, producing durable grayscale data or imagery at selected depths.
Why it is used
It adds a distinct inspection method to the credential and complements material, printed, personalized or machine-readable controls.
Security benefits
- Data integrated within the card body
- Strong relationship between material and personalization
- Support for tactile or multi-layer concepts
- Compatible with variable identity data
MATERIAL COMPATIBILITY
Integration starts with the card stack
This method requires laser-responsive polycarbonate layers and a card stack designed for the intended personalization equipment.
MANUFACTURING CONSIDERATIONS
Control points
- Layer sensitization
- Laser wavelength and equipment
- Image density and placement
- CLI/MLI and window relationships
