What it is
A security hologram is a diffractive optical feature that creates angle-dependent imagery and can be integrated into an overlay, laminate or card surface.
HOW IT WORKS
Technical principle
Micro- or nano-structured optical patterns redirect light to produce controlled visual changes. Original artwork can combine multiple visual zones for unaided inspection.
Why it is used
It adds a distinct inspection method to the credential and complements material, printed, personalized or machine-readable controls.
Security benefits
- Fast visual inspection
- Evidence of surface alteration
- Custom program identity
- Compatibility with layered security design
MATERIAL COMPATIBILITY
Integration starts with the card stack
Common integration routes include PET and PVC-compatible overlays and suitable laminate constructions. Optical clarity, bonding and process temperature must be reviewed.
MANUFACTURING CONSIDERATIONS
Control points
- Original authorized artwork
- Registered versus repeating placement
- Viewing angle and background contrast
- Lamination and coating compatibility
