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 a 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.

 Biometric security

Biometric security

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:

 Bar-code PDF 417

Bar-code PDF 417

2D barcode (two-dimensional barcode) storing data along two dimensions and is therefore capable of containing much more information than the 1D barcode.

Security Features

In order to guarantee the security of your documents and no falsification, a great number of techniques are offered:

 Paper characteristics

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. OVI Printing ink containing optically variable pigments will show large color shifts (strong variations in color) depending on the angle of observation or lighting.

 Optically variable ink (OVI)

Optically variable ink (OVI)

Printing ink containing optically variable pigments will show large color shifts (strong variations in color) depending on the angle of observation or lighting.

 UV ink

UV 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.

 Photochromic ink

Photochromic ink

Pattern appearing under the sunlight, remaining observable some time after exposure.

 Guillochis

Guillochis

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

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.

 Microprint

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

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

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.
