Kinegram (security technology)
A Kinegramm ( Greek κίνησις Kinesis , German , movement ' and γράμμα [gramma] = "Written") or Kinegram ( registered trademark of OVD Kinegram AG) is a proprietary technology to protect against forgery of banknotes , metal bars , passports , visas and identity cards by Tilt effect . It is safety as "OVD" ( O ptically V ariable D denotes evice = optically variable feature). The patented technology of the kinegram was originally developed for telephone cards by the Swiss company Landis & Gyr Communication in the 1980s . The company operates today as OVD Kinegram AG .
In contrast to the hologram , which has three-dimensional elements, the mostly silvery shiny kinegrams represent a two-dimensional movement sequence. The name is derived from the term kinematics , because depending on the angle at which the kinegram is viewed, a clearly defined film-like sequence takes place.
In 1988, was Austrian 5000 Schilling - banknote applied with a Kinegramm and was the first bill, which was provided with a foil application. In Germany, with the fourth and last series of DM banknotes from the end of 1997, kinegrams were introduced for the first time on notes with the face value of 50, 100 and 200 DM. The front of the euro banknotes also features kinegram elements that switch between the euro symbol and the respective value when tilted . The kinegram technique is also used in other security documents, such as B. for Visa and German vehicle registration documents .

Kinegrams on a certified gold bar
It is also possible to emboss a security element in the form of microstructures directly onto the surface of the underside of an embossed gold bar , the hologram-like optical effect being created by the film into which the certified bar is welded. The so-called kinebars are produced exclusively by the manufacturer Argor-Heraeus , who acts as the licensee of the kinegram technology from OVD Kinegram AG . Since 1994, Argor-Heraeus has minted kinebars both under its own name and for a few selected third parties.
