Semlex Products: Visas
Semlex visa meets the recommendations of the document N°9303 part. 2 from the ICAO (International Civil Aviation Organization) and the dimensions of the machine readable visa will be conform to the ISO 7810 format ID3 : 88 mm (+/-0.75mm) x 125 mm (+/-0.75 mm).
Moreover the passport will contain an MRZ (Machine Readable Zone) which will allow an automatic reading of the name, passport number, nationality, birth date, sex, expiring date and personal identification number.
Zone I : Heading
Zone II : Personal data zone
Zone III : Document data zone
Zone IV : Signature
Zone V : Identification zone
Zone VI : Facultative zone
Zone VII : Machine readable zone (MRZ)
1. Biometric features
A personal biological (anatomical or physiological) or behavioral characteristic which can be used to establish a person's identity by comparing it with stored reference data. Traditionally, the most popular biometric identifier is the fingerprint. Other frequently used biometric identifiers include the facial image, iris image and hand geometry.
Semlex integrates biometric features through different means:
2D bar-code
2D barcode (two-dimensional barcode) storing data along two dimensions and is therefore capable of containing much more information than the 1D barcode.
2. Security features
In order to guarantee the security of your documents and no falsification, a great number of techniques are offered:
Paper characteristics
Booklet paper will offer appropriate ruggedness and absorption characteristics. fibers with fluorescent properties (visible under UV light) which are mixed into the paper pulp during the paper manufacturing process to serve as a security feature.
They may be visible (colored fibers) or invisible under normal light.
Fugitive ink
A type of soluble ink which dissolves in certain solvents or water against falsification attempts.
Printing ink containing optically variable pigments will show large color shifts (strong variations in color) depending on the angle of observation or lighting.
Fluorescent ink
Ink containing fluorescent substances (pigments) which is used to print text or motifs. This type of ink is visible under normal light and fluoresces under UV light.
Iridescent ink
Thin film deposited on tiny mica flakes causing interferences with the incident light. This creates shiny, pearl-like shimmering effects.
Photochromic ink
Photochromic inks change their color when exposed to UV light and remain for a certain time before the color reverts to its original state.
Guilloches
Fine (intricate) designs consisting of interlaced continuous lines arranged in geometric patterns with the aim of raising the barrier for re-origination and reproduction.
Rainbow coloring
This coloring process used in offset printing is used to protect security documents against color separation or copying, by subtly merging colors into each other resulting in a gradual color change.
Anti scan/copy patterns
Printed security features integrated in the background printing to protect against simulation through copying. The printed images and patterns contain embedded (hidden) information that is invisible to the naked eye under normal inspection conditions but becomes visible or legible, or causes flaws (mistakes) to appear after copying or reproduction with a scanner.
Microprint
Lines or motifs made up of very small letters or numbers that are barely perceptible to the eye that basic methods of reproduction can't reproduce.
Hologram
Diffractive Optically Variable Image Device used as a security element. A number of effects are possible, e.g. 2D holograms (2-dimensional holograms) with structural and color changes, 3D holograms with images, holograms with kinematic effects, etc.
Serial number
A unique sequential number that is printed or perforated in a document and assigned for identification; this uniqueness allows a document to be traced if it is lost or stolen.
