Description

Datenträger in Kartenform Data carriers in card form
Die Erfindung betrifft einen Datenträger in Kartenform, beispielsweise einen Personalausweis, eine Scheck- oder Kreditkar- te, einen Sicherheitsausweis, eine Gesundheitskarte, eine Clubkarte, eine Computerkarte, eine Fahrkarte, eine Versicherungs- karte, eine Karte mit einem Werteinheitenspeicher, eine Schlüsselkarte, eine Kundenkarte, etc. Auf dem Datenträger ist Information sichtbar und/oder unsichtbar aufgebracht . Beispielsweise können auf solchen Datenträgern Bild- und/oder Textdaten codiert und/oder uncodiert aufgedruckt, eingeprägt, eingestanzt, oder sonstwie aufgebracht sein.The invention relates to a data carrier in the form of a card, for example an identity card, a check or credit card, a security card, a health card, a club card, a computer card, a ticket, an insurance card, a card with a value unit memory, a key card, one Customer card, etc. Information is visible and / or invisible on the data carrier. For example, image and / or text data can be encoded and / or uncoded, printed, embossed, punched, or otherwise applied on such data carriers.
Solche Datenträger sollen häufig gegen eine nachträgliche Mani- pulation bzw. ein Kopieren geschützt werden. Als Kopierschutz sind bereits verschiedene Maßnahmen bekannt, beispielsweise Hologramme in Form von kleinen Siegeln auf einer Kartenaußenseite unlösbar anzubringen, welche sich mit handelsüblichen Kopiergeräten nicht kopieren lassen.Such data carriers are often to be protected against subsequent manipulation or copying. Various measures are already known as copy protection, for example to permanently attach holograms in the form of small seals on the outside of a card, which cannot be copied with commercially available copying machines.
Der Erfindung liegt die Aufgabe zugrunde, den Datenträger in Kartenform kostengünstig gegen einfaches Kopieren zu schützen.The invention has for its object to protect the data carrier in card form inexpensively against simple copying.
Die Erfindung löst diese Aufgabe mit dem Gegenstand des An- spruchs 1. Weitere bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben. Danach ist der Datenträger in Kartenform, der eine von außen sichtbare und/oder unsichtbare Information trägt, insgesamt transparent ausgestaltet. Dies erschwert vorteilhaft ein Kopieren der Karte, da auf transparente Materialien als Kopiermedien mit handelsüblichen Kopierern - wenn überhaupt - nur mit deutlichem Qualitätsverlust kopiert werden kann. Die Information ist optisch sichtbar aufgebracht, wobei sie aufgrund der Transparenz von beiden Außenseiten ausgelesen werden kann. Zusätzlich kann Information beispielsweise noch unsichtbar auf einem Magnetstreifen gespeichert sein, der von außen mittels eines geeigneten Lesegeräts ausgelesen werden kann. Dann kann die Karte im Bereich des Magnetstreifens bei Verwendung eines nicht transparenten Magnetstreifens dort ebenfalls nicht transparent sein. Die sichtbare Information nimmt jedoch einen im Vergleich zum gesamten .Kartenkörper geringen Flächenanteil ein, damit die transparente Eigenschaft der gesamten Karte überwiegt. Die gesamte Karte kann auch vollständig transparent sein, wobei die Karte dann eine unsichtbare Information enthält, die beispielsweise nur mit einem speziellen Lesegerät, einem Laser mit einem bestimmten schmalen Frequenzbereich (Infrarot, Ultraviolett, etc.), usw. ausgelesen werden kann.The invention solves this problem with the subject matter of claim 1. Further preferred embodiments of the invention are described in the subclaims. According to this, the data carrier in card form, which carries information which is visible and / or invisible from the outside, is designed to be transparent overall. This advantageously makes it difficult to copy the card, since, if at all, copying onto transparent materials as copying media with commercially available copiers is only possible with a significant loss in quality. The information is visually applied, and can be read from both outside due to the transparency. In addition, information can, for example, still be stored invisibly on a magnetic strip, which can be read from the outside by means of a suitable reading device. Then the card in the area of the magnetic strip can also be non-transparent when using a non-transparent magnetic strip. However, the visible information occupies a small area compared to the entire card body, so that the transparent property of the entire card predominates. The entire card can also be completely transparent, the card then containing invisible information which can only be read out, for example, using a special reading device, a laser with a specific narrow frequency range (infrared, ultraviolet, etc.), etc.
Bevorzugt ist der Datenträger als Laminat aus mehreren transparenten Schichten ausgestaltet, wobei die von außen sichtbare Information auf einer der inneren Schichten des Laminats aufgebracht ist. Vorteilhaft wird hierdurch die Kopiersicherheit nochmals erhöht, da somit nicht einfach auf eine transparente Plastikfolie kopiert werden kann, bei der dann nach dem Kopieren der Toner bzw. die Tinte auf einer Außenseite der Folie aufgebracht wäre und nicht im Inneren der Karte, was anhand des Erscheinungsbild der Karte leicht geprüft werden kann.The data carrier is preferably designed as a laminate of a plurality of transparent layers, the information visible from the outside being applied to one of the inner layers of the laminate. This advantageously increases the copy security, since it is therefore not easy to copy onto a transparent plastic film, in which the toner or ink would then be applied to an outside of the film after copying and not inside the card, which is due to the appearance the card can be easily checked.
Zwecks erhöhtem Kopierschutz weist der Datenträger bevorzugt eine das Licht beugende, brechende, absorbierende, streuende und/oder reflektierende Struktur auf. Dies können beispielsweise Metallfolien und/oder ein transparenter Bereich mit einem eingeprägten Beugungsgitter sein, daß je nach Betrachtungswinkel das Licht in unterschiedlicher Farbe reflektiert und/oder durchläßt. Die lichtbeugende Struktur kann beispielsweise bei For the purpose of increased copy protection, the data carrier preferably has a structure which diffracts, refracts, absorbs, scatters and / or reflects. These can be, for example, metal foils and / or a transparent area with an embossed diffraction grating that, depending on the viewing angle, reflects and / or transmits the light in different colors. The light diffractive structure can be, for example

Diese Kombination stellt aufgrund ihres einzigartigen Erscheinungsbildes (in Regenbogenfarben schillerndes Transmissionshologramm und ein in der Regel einfarbiges Reflexionshologramm) ein besonders gut erkennbares Sicherheitsmerkmal dar, das einerseits nur schwer zu kopieren ist und andererseits leicht identifiziert werden kann.

For further details regarding the combination of these two types of hologram, reference is made to German patent application 199 24 385.9 by the same applicant.
