Laser engraving on plastic cards is a high-security personalization technology that uses a focused laser beam to permanently mark the card surface or internal layers. Instead of using ink, the laser alters the material structure of polycarbonate or PVC cards to create text, images, and security features such as MLI/CLI and ghost images. This ensures durability, tamper resistance, and long-term readability. PIOTEC card laser systems like CPL300 ID card laser engraving machine integrate precision laser engraving modules, enabling high-resolution personalization for secure ID cards, passports, and driver's licenses without consumables.
