Machine-readable technology (MRT): Magnetic stripe, smart card, bar codes, OCR, optical WORM media, etc.
Verifies the authenticity of the document, the data or the person presenting the card by the use of a reader and
comparison of the stored data to other machine or visual information
Magnetic media fingerprinting: Tracks unique, random patterns of magnetic media formed as a by-product
manufacture of card. The pattern is recorded at the time the card is encoded and this pattern can later be compared
to the pattern detected when the card is scanned.
Metallic ink: Ink exhibiting a metallic-like appearance.
Metameric inks: A pair of inks formulated to appear to be the same color when viewed under specified conditions,
normally daylight illumination, but which are mismatched at other wavelengths.
Micro optical imaging: Text, line art, gray scale images and multi-reflectivity images are engineered into optical
WORM media at high resolution (over 12,000 dpi). Difficult to simulate the printing resolution.
Micro- printed text: Very small text printed in positive and/or negative form, that may be used in conjunction with
rainbow printing and which can only be read with the aid of a magnifying glass and not exceeding 0.3mm in height.
Multi-layer card: A card-body comprising two or more layers of material securely bonded together to form a single
structure.
Non optical effects pigments: Any ink containing visible or invisible pigments which is not designed to be controlled
by eye such as metallic ink, magnetic ink, conductive ink, bleeding ink or which is not showing any predictable
behavior upon wavelength activation.
Non-standard type fonts: Type fonts that are of restricted availability.
Optical effect pigment: Visible or invisible pigments incorporated in an ink which is designed to be controlled by eye,
such as: optically variable ink also called color shifting inks, or iridescent inks.
Optical media fingerprinting: Tracks unique, random patterns of optic media (e.g., fibers) on card. The pattern is
recorded at the time the card is encoded and this pattern can later be compared to the pattern detected when the
card is scanned.
Optically variable element: An element whose appearance in color and/or design changes dependent upon the
angle of viewing or illumination, such as holograms or optical diffractive structures.
Optically Variable Ink: Printing ink containing optically variable pigments which show variations in color depending
on the angle of observation or lighting. Optically variable inks can be either opaque or transparent and include
iridescent inks and metameric inks.
Overlay: An ultra-thin film or protective coating that may be applied to the surface of a DL/ID in place of a laminate
and which may contain optically variable elements.
Personalization: The process by which the dynamic data elements (portrait, signature, biographical and all personal
data) are applied to the DL/ID.
Personalized tactile element: A surface element giving a distinctive 'feel' to the DL/ID, such as laser embossing
(also referred to as raised laser engraving).
Phosphorescent ink: Ink containing a pigment, which glows when exposed to light of a specific wavelength, the
reactive glow remaining visible and then fading after the light source is removed.
