Security feature vocabulary every buyer should know

Vendor descriptions and review threads use specific terminology that means something precise. Here are the terms that come up most often and what they actually refer to.

• Laser engraving — A process where a laser burns information directly into the card substrate rather than printing on the surface. Laser-engraved data cannot be altered without visibly damaging the card. Higher-security cards use laser engraving for photos and personal data.
• Tactile print / intaglio effect — Raised printing you can feel with a fingertip. Created by depositing thick ink layers. Some states use this on specific card elements. Different from laser engraving, which creates a depression rather than a raised surface.
• Microprint — Text printed small enough (under 0.5mm tall) to appear as a line or rule to the unaided eye. Under magnification, the text is readable. Used as a security feature because it is difficult to reproduce at sufficient quality without controlled printing equipment.
• Full-face OVD — A holographic overlay that covers the entire card face. More difficult to alter than a smaller overlay patch because any manipulation of the card surface disturbs the hologram across the full area.
• Polycarbonate laminate vs surface laminate — On a polycarbonate card, personal data is printed between poly layers and bonded at high temperature. On a surface laminate card, a protective film is applied over printed data on a substrate. PC laminate is harder to delaminate or alter.
• DMV format / AAMVA compliance — Whether the barcode data follows the standardized format used by actual motor vehicle departments. Non-compliant barcodes may decode but produce incorrect or missing fields when read by AAMVA-aware scanner software.
• Ghost image — A secondary photo printed at lower opacity in a specific zone of the card. State-specific in both presence and placement.

Building your vocabulary around these terms makes vendor communication more precise. When you can name the specific feature you want checked — OVI, ghost image placement, laser-engraved tactile zone — vendors can give you accurate answers rather than generic quality assurances. Precise terminology also helps you read forum discussions more accurately and evaluate whether a review is describing something that matters for your specific use case.
