Description

Die vorliegende Erfindung betrifft einen kartenförmigen Datenträger mit einem mehrschichtig aufgebauten, flächigen Kartenkörper.The present invention relates to a card-shaped data carrier with a multi-layer, flat card body.

Es ist bekannt, als Sicherheitsmerkmal für papierartige Wertdokumente, wie zum Beispiel Banknoten oder dergleichen, Sicherheitsfäden aus verschiedenen Materialien zu verwenden, die nicht kopierfähig und nur mit unverhältnismäßigem Aufwand zu fälschen sind. Zum Beispiel werden holographischen Sicherheitsfäden in Form von diffraktiven Oberflächenelementen auf geeignete Kunststofffolien aufgebracht oder in diese eingebracht und bei der Papierherstellung in Sicherheitspapier integriert, welches dann zu Banknoten weiterverarbeitet wird.It is known to use security threads made of different materials as a security feature for paper-like documents of value, such as bank notes or the like, which cannot be copied and can only be forged with disproportionate effort. For example, holographic security threads in the form of diffractive surface elements are applied to or introduced into suitable plastic films and integrated into security paper during paper production, which is then processed further into banknotes.

Während sich die Verwendung von Sicherheitsfäden insbesondere im Banknotenbereich bewährt hat, werden kartenförmige Datenträger und Identitätskarten aus Kunststoff in der Regel nicht mit Sicherheitsfäden ausgestattet, da die aus dem Banknotenbereich bekannten optischen Effekte bei Kunststoffkarten nicht ohne Weiteres hervorgerufen werden können.While the use of security threads has proven itself particularly in the banknote sector, card-shaped data carriers and identity cards made of plastic are generally not equipped with security threads, since the optical effects known from the banknote sector cannot easily be produced in plastic cards.

Die WO 2015/085505 A1 zeigt optisch variable Sicherheitsfäden oder Sicherheitsstreifen, die in oder auf Sicherheitsdokumenten eingearbeitet sind.The WO 2015/085505 A1 shows optically variable security threads or security strips that are incorporated into or on security documents.

Insofern ist es die Aufgabe der vorliegenden Erfindung, die Fälschungssicherheit von kartenförmigen Datenträgern mit Hilfe von Sicherheitsfäden zu erhöhen.In this respect, it is the object of the present invention to increase the security against forgery of card-shaped data carriers with the aid of security threads.

Diese Aufgabe wird durch einen kartenförmigen Datenträger mit den Merkmalen des unabhängigen Anspruchs gelöst. In den davon abhängenden Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung angegeben.This object is achieved by a card-shaped data carrier with the features of the independent claim. In the dependent Advantageous embodiments and developments of the invention are specified in the claims.

Ein erfindungsgemäßer Datenträger umfasst einen mehrschichtig aufgebauten, flächigen Kartenkörper mit einer flächigen Oberseite und einer flächigen Unterseite. Der Datenträger ist kartenförmig und vorzugsweise als Kunststoffkarte ausgebildet, zum Beispiel als Bank- oder Kreditkarte, Smartcard, Ausweis- oder Reisedokuments oder dergleichen. Der Kartenkörper umfasst mehrere übereinander liegende Schichten, vorzugsweise Kunststoffschichten, unter anderen die erfindungsgemäße Kombination aus einem Hologrammstreifen und eine flächig ausgebildete Streifenfolienschicht, welche alternierende beziehungsweise abwechselnd angeordnete, transparente und im Wesentlichen opake streifenförmige Bereiche aufweist. Der Kartenkörper umfasst unter dem Hologrammstreifen zumindest eine im Wesentlichen opake Schicht so dass der Hologrammstreifen auf der Unterseite des Kartenkörpers im Auflicht nicht sichtbar ist und im Durchlicht lediglich schattenartig sichtbar ist, wobei der Kartenkörper unter der zumindest einen im Wesentlichen opaken Schicht einen weiteren Hologrammstreifen und darunter eine weitere Streifenfolienschicht umfasst, so dass der weitere Hologrammstreifen auf der Unterseite des Kartenkörpers im Auflicht durch die transparenten Bereiche der weiteren Streifenfolienschicht hindurch abschnittsweise sichtbar ist. Gesehen von einer Seite des Kartenkörpers ist die Streifenfolienschicht vor dem Hologrammstreifen angeordnet, sodass der Hologrammstreifen von einer seite aus betrachtet im Auflicht nur durch die transparenten Bereiche der Streifenfolienschicht hindurch sichtbar ist, während die im Wesentlichen opaken Bereich der Streifenfolienschicht den Hologrammstreifen abschnittsweise verdecken.A data carrier according to the invention comprises a multilayer, flat card body with a flat top and a flat bottom. The data carrier is card-shaped and preferably designed as a plastic card, for example as a bank or credit card, smart card, ID or travel document or the like. The card body comprises several superimposed layers, preferably plastic layers, including the combination according to the invention of a hologram strip and a flat strip film layer which has alternating or alternating, transparent and essentially opaque strip-shaped areas. The card body comprises at least one essentially opaque layer under the hologram strip so that the hologram strip on the underside of the card body is not visible in incident light and is only visible in the form of a shadow in transmitted light, the card body having a further hologram strip under the at least one essentially opaque layer and below comprises a further strip film layer, so that the further hologram strip on the underside of the card body is visible in sections in incident light through the transparent areas of the further strip film layer. Seen from one side of the card body, the strip film layer is arranged in front of the hologram strip, so that the hologram strip, viewed from one side in incident light, is only visible through the transparent areas of the strip film layer, while the essentially opaque areas of the strip film layer cover the hologram strip in sections.

Angaben zur relative Position oder Lage der einzelnen Schichten des Kartenkörpers werden in der Regel ausgehend der Oberseite oder Unterseite des Kartenkörpers angegeben. Eine Schicht, die bei Betrachtung der Oberseite des Datenträgers vor einer anderen Schicht liegt, liegt also bezüglich einer Schnitt- bzw. Seitenansicht des Kartenkörpers über oder oberhalb dieser anderen Schicht. Eine Schicht, die bei Betrachtung der Unterseite des Datenträgers vor einer anderen Schicht liegt, liegt demnach bezüglich einer Schnitt- oder Seitenansicht des Kartenkörpers unter oder unterhalb der anderen Schicht.Information on the relative position or location of the individual layers of the card body is usually given starting from the top or bottom of the card body. A layer which, when viewed from the top of the data carrier, lies in front of another layer, is therefore with respect to one Sectional or side view of the card body above or above this other layer. A layer which, when viewed from the underside of the data carrier, lies in front of another layer, accordingly lies below or below the other layer with regard to a sectional or side view of the card body.

Die im Wesentlichen opaken Bereiche der Streifenfolienschicht sind weder vollständig opak, also lichtundurchlässig, noch sind sie transparent. Vielmehr weisen sie eine wahrnehmbare Transluzenz auf, die allerdings gering sein kann. Die Niveau der Opazität der im Wesentlichen opaken Streifen ist also derart, dass im Auflicht hinter bzw. unter den im Wesentlichen opaken Bereichen liegende Strukturen des Kartenkörpers nicht sichtbar sind, während solche Strukturen im Durchlicht aufgrund eines lichtstreuenden und gegebenenfalls auch reflektierenden Effekts der im Wesentlichen opaken Bereiche diffus, schattenartig bzw. getrübt sichtbar sind. Die Transmission (T) der im Wesentlichen opaken Bereiche ist hierbei kleiner als eins (T < 1), vorzugsweise deutlich kleiner als eins, zum Beispiel T < 0,8 oder T < 0,5.The essentially opaque areas of the strip film layer are neither completely opaque, that is, opaque to light, nor are they transparent. Rather, they have a perceptible translucency, which, however, can be low. The level of opacity of the essentially opaque strips is such that in reflected light behind or below the essentially opaque areas of the card body structures are not visible, while such structures in transmitted light due to a light-scattering and possibly also reflective effect of the essentially opaque Areas are diffuse, shadowy or cloudy. The transmission (T) of the essentially opaque areas is less than one (T <1), preferably significantly less than one, for example T <0.8 or T <0.5.

Die alternierenden streifenförmigen Bereiche der Streifenfolienschicht können sich parallel verlaufend über die gesamte Fläche der Streifenfolienschicht erstrecken, diese also vollständig bedecken. Ebenso können die streifenförmigen Bereiche auch nur in einem bestimmten flächigen Ausschnitt der Streifenfolienschicht vorliegen, während der Rest der Streifenfolienschicht transparent, transluzent oder opak ist. Wichtig für die Erfindung ist lediglich, dass die streifenförmigen Bereiche der Streifenfolienschicht in flächiger Beziehung zu dem Hologrammstreifen stehen, diesen also bedecken, so dass sich der erfindungsgemäße optische Effekt einstellt, dass die transparenten und die im Wesentliche opaken streifenförmigen Bereiche den Hologrammstreifen im Auflicht alternierend, abschnittsweise verdecken und freigeben.The alternating strip-shaped regions of the strip film layer can extend in parallel over the entire surface of the strip film layer, that is to say cover it completely. Likewise, the strip-shaped areas can also only be present in a certain flat section of the strip film layer, while the rest of the strip film layer is transparent, translucent or opaque. It is only important for the invention that the strip-shaped areas of the strip film layer are in a two-dimensional relationship with the hologram strip, i.e. cover it, so that the optical effect according to the invention is established that the transparent and the essentially opaque strip-shaped areas alternate the hologram strip in incident light, cover and release in sections.

Vorzugsweise ist die Streifenfolienschicht in dem Kartenkörper derart relativ zu dem Hologrammstreifen angeordnet, dass die parallele Ausrichtung der alternierenden, streifenförmigen Bereiche und die Ausrichtung des Hologrammstreifens einen ausreichend großen Winkel bilden, damit der Hologrammstreifen durch mehrere der transparenten Bereiche der Streifenfolienschicht hindurch sichtbar ist und dazwischen von mehreren der im Wesentlichen opaken Bereiche bedeckt wird, sodass der Hologrammstreifen von der Oberseite des Kartenkörpers aus betrachtet im Auflicht lediglich abschnittsweise sichtbar ist.The strip film layer is preferably arranged in the card body relative to the hologram strip in such a way that the parallel alignment of the alternating, strip-shaped regions and the alignment of the hologram strip Form a sufficiently large angle so that the hologram strip is visible through several of the transparent areas of the strip film layer and is covered in between by several of the substantially opaque areas so that the hologram strip is only partially visible in incident light when viewed from the top of the card body.

Auf diese Weise entsteht bei Betrachten der Oberseite des Kartenkörpers der Eindruck eines Hologrammstreifens, der mehrfach abschnittsweise an die Oberfläche des Datenträgers tritt und anschließend wieder in dem Kartenkörper verschwindet. Diesen optisch komplexen Eindruck kennt der Nutzer eines erfindungsgemäßen Datenträgers, also etwa eines Identitätsdokuments aus Kunststoff im Format ID-1 oder ID-3 gemäß ISO/IEC7810, als wichtiges Sicherheitsmerkmal aus dem Banknotenbereich, was sein Vertrauen in die Echtheit des Identitätsdokuments erhöht. Die Gestaltung der Hologrammstreifen kann sich an derjenigen von Hologramm-Sicherheitsfäden im Banknotenbereich orientieren und insbesondere zwischen 1 und 2 mm breit und als Diffraktionsstruktur ausgebildet sein, gegebenenfalls ergänzt durch Demetallisierungen, metallische oder Farbaufdrucke, oder andere Applikationen, die optisch variable, Kipp- oder Farbwechseleffekte hervorrufen.In this way, when looking at the top of the card body, the impression of a hologram strip is created, which appears several times in sections on the surface of the data carrier and then disappears again in the card body. The user of a data carrier according to the invention, such as an identity document made of plastic in the format ID-1 or ID-3 according to ISO / IEC7810, is familiar with this optically complex impression as an important security feature from the banknote sector, which increases their confidence in the authenticity of the identity document. The design of the hologram strips can be based on that of hologram security threads in the banknote area and in particular be between 1 and 2 mm wide and designed as a diffraction structure, optionally supplemented by demetallization, metallic or color prints, or other applications that create optically variable, tilting or color change effects cause.

Vorzugsweise umfasst der Kartenkörper oberhalb der Streifenfolienschicht und/oder unterhalb des Hologrammstreifens eine, gegebenenfalls auch mehrere transparente Deckfolienschichten, die die Oberseite bzw. Unterseite des Kartenkörpers bilden. Der Hologrammstreifen ist dann von der Oberseite des Kartenkörpers aus betrachtet im Durchlicht durch die transparenten Bereiche der Streifenfolienschicht hindurch deutlich sichtbar und durch im Wesentlichen opaken Bereiche der Streifenfolienschicht hindurch lediglich schattenartig sichtbar. Die Fälschungssicherheit des Datenträgers wird hierdurch weiter erhöht, da die unterschiedlichen optischen Eindrücke im Auflicht und Durchlicht nicht mehr nur alleine von der Streifenfolienschicht und dem Hologrammstreifen abhängen, sondern zusätzlich auch von den weiteren Folienschichten des flächigen Kartenkörpers.The card body preferably comprises above the strip film layer and / or below the hologram strip one, optionally also several transparent cover film layers which form the top or bottom of the card body. The hologram strip is then clearly visible in transmitted light through the transparent areas of the strip film layer, viewed from the top of the card body, and is only visible in shadow-like fashion through essentially opaque areas of the strip film layer. This makes the data carrier forgery-proof further increased, since the different optical impressions in incident light and transmitted light no longer depend solely on the strip film layer and the hologram strip, but also on the further film layers of the flat card body.

Derartige transparente Deckschichten auf der Oberseite und/oder der Unterseite des Kartenkörpers, die bei allen Ausführungsformen der vorliegenden Erfindung vorgesehen sein können, schützen die Anordnung aus Streifenfolienschicht und Hologrammstreifen vor Abnutzungen und verbessern gegebenenfalls auch die Wirkung der hervorgerufenen optischen Effekte. Diese Deckfolienschichten sind vorzugsweise aus einem transparenten Kunststoff gefertigt und können dort, wo der Hologrammstreifen nicht sichtbar ist, zusätzlich bedruckt sein, zum Beispiel mit Namen, Identifikationsnummern, biometrischen oder sonstigen Sicherheitsaufdrucken oder dergleichen.Such transparent cover layers on the upper side and / or the lower side of the card body, which can be provided in all embodiments of the present invention, protect the arrangement of strip film layer and hologram strip from wear and tear and, if necessary, also improve the effect of the optical effects caused. These cover film layers are preferably made of a transparent plastic and can be additionally printed where the hologram strip is not visible, for example with names, identification numbers, biometric or other security prints or the like.

Bei allen Ausführungsformen der vorliegenden Erfindung ist der Hologrammstreifen vorzugsweise in eine Hologrammfolienschicht integriert, sodass der erfindungsgemäße Datenträger eine gleichmäßige Dicke aufweist. Die Hologrammfolienschicht ist hierbei vorzugsweise eine transparente Kunststofffolie, die den Hologrammstreifen als diffraktives Oberflächenelement umfasst. Die Hologrammfolienschicht kann auch mehrere Hologrammstreifen umfassen, die eine vorgesehene geometrische Anordnungen bilden oder anderweitig in Beziehung zueinander stehen, beispielsweise durch aufeinander abgestimmte, optisch variable Bilder. Die Hologrammfolienschicht kann auch weitere Sicherheitsmerkmale umfassen, die dann ebenfalls abschnittsweise durch die Streifenfolienschicht hindurch sichtbar sein können, beispielsweise Text oder Grafikelemente, oder auch Sicherheitsmerkmale, die nur unter bestimmten Beleuchtungsbedingungen sichtbar werden, zum Beispiel unter UV- oder polarisiertem Licht.In all embodiments of the present invention, the hologram strip is preferably integrated into a hologram film layer, so that the data carrier according to the invention has a uniform thickness. The hologram film layer is here preferably a transparent plastic film which comprises the hologram strip as a diffractive surface element. The hologram film layer can also comprise a plurality of hologram strips which form an intended geometric arrangement or are otherwise related to one another, for example by means of optically variable images that are matched to one another. The hologram film layer can also include further security features, which can then also be visible in sections through the strip film layer, for example text or graphic elements, or security features that are only visible under certain lighting conditions, for example under UV or polarized light.

Bei einer bevorzugten Ausführungsform der vorliegenden Erfindung umfasst der Kartenkörper zusätzlich zu der bisher beschriebenen, oberhalb des Hologrammstreifens angeordneten Streifenfolienschicht eine weitere Streifenfolienschicht unterhalb des Hologrammstreifens. Bei dieser Ausführungsform wird der Hologrammstreifen als durch die beiden Streifenfolienschichten eingeschlossen. Auch die weitere Streifenfolienschicht weist alternierende, transparente und im Wesentlichen opake streifenförmige Bereiche auf.In a preferred embodiment of the present invention, the card body comprises, in addition to the previously described strip film layer arranged above the hologram strip, a further strip film layer below the hologram strip. In this embodiment, the hologram strip is enclosed by the two strip film layers. The further strip film layer also has alternating, transparent and essentially opaque strip-shaped areas.

Die beiden Streifenfolienschichten sind in dem Kartenkörper vorzugsweise derart zueinander ausgerichtet, dass deren streifenförmige Bereiche einerseits in die gleiche Richtung weisen und dass andererseits die transparenten, streifenförmigen Bereich der einen Streifenfolienschicht, etwas der oberhalb des Hologrammstreifens angeordneten Streifenfolienschicht, möglichst genau über oder auf den im Wesentlichen opaken streifenförmigen Bereichen der jeweils anderen Streifenfolienschicht liegen, etwa der unterhalb des Hologrammstreifens angeordneten Streifenfolienschicht. Vorzugsweise ist die Abstimmung der transparenten Bereiche der einen der beiden Streifenfolienschichten auf die im Wesentlichen opaken Bereiche der jeweils anderen der beiden Streifenfolienschichten registergenau.The two strip film layers are preferably aligned with one another in the card body in such a way that their strip-shaped areas on the one hand point in the same direction and that on the other hand the transparent, strip-shaped areas of one strip film layer, somewhat of the strip film layer arranged above the hologram strip, as precisely as possible over or on the essentially opaque strip-shaped areas of the respective other strip film layer lie, for example the strip film layer arranged below the hologram strip. The matching of the transparent areas of one of the two strip film layers to the essentially opaque areas of the respective other of the two strip film layers is preferably accurate in register.

Auf diese Weise ist der Hologrammstreifen sowohl von der Oberseite als auch der Unterseite des Kartenkörpers aus betrachtet im Auflicht alternierend, abschnittsweise sichtbar, während der Hologrammstreifen sowohl von der Oberseite als auch von der Unterseite des Kartenkörpers aus betrachtet im Durchlicht abwechseln deutlich und schattenartig sichtbar ist. Der Hologrammstreifen ist im Durchlicht nämlich durch die transparenten streifenförmigen Bereiche der jeweils betrachteten Streifenfolienschicht hindurch deutlich sichtbar, während durch die opaken streifenförmigen Bereiche der jeweils betrachteten Streifenfolienschicht diejenigen Abschnitte des Hologrammstreifens lediglich schattenartig sichtbar sind, die von der jeweils anderen Seite des Kartenkörpers aus betrachtet durch die transparenten streifenförmigen Bereiche der anderen Streifenfolienschicht wiederum deutlich sichtbar sind.In this way, the hologram strip is alternately visible in incident light, viewed from both the top and the underside of the card body, while the hologram strip, viewed from both the top and the bottom of the card body, is alternately clearly and shadowy visible in transmitted light. The hologram strip is clearly visible in transmitted light through the transparent strip-shaped areas of the respective strip film layer being viewed, while through the opaque strip-shaped areas of the The strip film layer viewed in each case only shows those sections of the hologram strip that are only visible in a shadow-like manner which, viewed from the other side of the card body, are clearly visible through the transparent strip-shaped areas of the other strip film layer.

Beim Betrachter entsteht hier also der Eindruck eines Hologrammstreifens, der alternierend zwischen der Ober- und der Unterseite des Kartenkörpers hin und her wechselt und, wenn er auf der vom Betrachter abgewandten Seite deutlich sichtbar ist, durch den Kartenkörper hindurch scheint und dennoch schattenartig wahrgenommen wird.The viewer thus has the impression of a hologram strip that alternates between the top and bottom of the card body and, if it is clearly visible on the side facing away from the viewer, shines through the card body and is nevertheless perceived like a shadow.

In dem erfindungsgemäßen kartenformigen Datenträger ist unterhalb des Hologrammstreifens eine flächige, im Wesentlichen opake Schicht angeordnet, sodass der Hologrammstreifen von der Oberseite aus betrachtet im Auflicht alternierend, abschnittsweise sichtbar ist und von der Unterseite aus betrachtet nicht sichtbar ist, da die im Wesentlichen opake Schicht von dort die Sicht auf den Hologrammstreifen jedenfalls im Auflicht verdeckt. Im Durchlicht ist der Hologrammstreifen von der Oberseite aus betrachtet alternierend abschnittsweise deutlich und abschnittsweise lediglich schattenartig sichtbar, während der Hologrammstreifen von der Unterseite aus betrachtet als schattenartiger Streifen durchgehend sichtbar ist.In the card-shaped data carrier according to the invention, a flat, essentially opaque layer is arranged below the hologram strip, so that the hologram strip is alternately visible in incident light when viewed from the top, and is not visible when viewed from the bottom, since the essentially opaque layer of there the view of the hologram strip is obscured in incident light. In transmitted light, the hologram strip, viewed from the top, is alternately clearly visible in sections and only visible in a shadow-like manner in sections, while the hologram strip, viewed from the bottom, is continuously visible as a shadow-like strip.

Ferner sind in dem erfindungsgemäßen kartenförmigen Datenträger unterhalb der im Wesentlichen opaken Schicht ein weiterer Hologrammstreifen und darunter eine weitere Streifenfolienschicht angeordnet. Die Abfolge dieser Schichten in dem Kartenkörper ist von der Oberseite aus betrachtet also: Streifenfolienschicht, Hologrammstreifen, im Wesentliche opake Schicht, weiterer Hologrammstreifen, weitere Streifenfolienschicht.Furthermore, in the card-shaped data carrier according to the invention, a further hologram strip is arranged below the essentially opaque layer and a further strip film layer underneath. The sequence of these layers in the card body is viewed from the top: strip film layer, hologram strip, Essentially opaque layer, further hologram strips, further strip film layer.

Bei dem erfindungsgemäßen Datenträger ist sowohl von der Oberseite als auch von der Unterseite des Datenträgers aus betrachtet im Auflicht einer der beiden Hologrammstreifen alternierend abschnittsweise sichtbar, während der in Blickrichtung jenseits der im Wesentlichen opaken Schicht liegende, andere Hologrammstreifen nicht sichtbar ist. Im Durchlicht ist wiederum von der Oberseite und der Unterseite aus betrachtet jeweils einer der beiden Hologrammstreifen durch die transparenten Bereiche der betreffenden Streifenfolienschicht hindurch deutlich sichtbar, während er durch die im Wesentlichen opaken Bereiche der betreffenden Streifenfolienschicht hindurch lediglich schattenartig sichtbar ist.In the case of the data carrier according to the invention, one of the two hologram strips is alternately visible in sections when viewed from the top as well as from the bottom of the data carrier, while the other hologram strip lying beyond the essentially opaque layer in the viewing direction is not visible. In transmitted light, viewed from the top and bottom, one of the two hologram strips is clearly visible through the transparent areas of the respective strip film layer, while it is only visible in the form of a shadow through the essentially opaque areas of the respective strip film layer.

In einer Ausführungsform liegen die Hologrammstreifen vorzugsweise in je einer Hologrammfolienschicht vor, sodass der Kartenkörper bzw. Datenträger eine konstante Dicke aufweist. Neben einem oder mehreren Hologrammstreifen können diese Hologrammfolienschichten zusätzlich geeignete Sicherheitsmerkmale aufweisen, die die betreffenden Hologrammstreifen auch überlagern können.In one embodiment, the hologram strips are preferably each in a hologram film layer, so that the card body or data carrier has a constant thickness. In addition to one or more hologram strips, these hologram film layers can additionally have suitable security features which can also overlay the relevant hologram strips.

Sämtliche beschriebenen Ausführungsformen können auf der Oberseite und/ oder der Unterseite des Kartenkörpers jeweils zumindest eine transparente Deckfolienschicht aufweisen, möglicherweise sogar mehrere. Ebenso können statt der beschriebenen einen im Wesentlichen opaken Schicht auch zwei oder mehrere übereinander liegende, im Wesentlichen opake Schichten eingesetzt werden, zum Beispiel um die Opazität der Gesamtschicht geeignet zu kontrollieren. Auch ist es möglich, zwei oder gar mehrere Hologrammfolienschichten in dem Kartenkörper direkt übereinander anzuordnen, falls dies Vorteile gegenüber einer einzelnen Hologrammfolienschicht mit zwei oder mehr Hologrammstreifen hat, beispielsweise weil eine bestimmte geometrische Anordnung der Hologrammstreifen auf diese Weise einfacher zu realisieren ist.All of the described embodiments can each have at least one transparent cover film layer on the top and / or the bottom of the card body, possibly even several. Likewise, instead of the one essentially opaque layer described, two or more essentially opaque layers lying one above the other can also be used, for example in order to suitably control the opacity of the overall layer. It is also possible to arrange two or even more hologram film layers in the card body directly one above the other, if this has advantages over a single hologram film layer with two or more hologram strips, for example because a specific geometric arrangement of the hologram strips can be implemented more easily in this way.

Bei allen Ausführungsformen sind die Ausmaße der beschriebenen Folienschichten derart, dass die erfindungsgemäßen optischen Effekte erzielt werden. Das heißt, die beschriebenen Folienschichten sind wenigstens so groß, dass die erfindungsgemäß erforderlichen Überlappungen möglich sind. Vorzugsweise haben die Folienschichten allerdings die Ausmaße des gesamten Kartenkörpers bzw. des kartenförmigen Datenträgers.In all embodiments, the dimensions of the film layers described are such that the optical effects according to the invention are achieved. That is to say that the film layers described are at least large enough to allow the overlaps required according to the invention. However, the film layers preferably have the dimensions of the entire card body or the card-shaped data carrier.

Vorzugsweise sind die erfindungsgemäßen kartenförmigen Datenträger nach ISO/IEC7810 als Identitätsdokumente im Format ID-1, ID-2 oder ID-3 ausgestaltet und können insofern sämtliche weiteren Sicherheitsmerkmale und Funktionen bereitstellen, die für solche Identitätsdokumente üblich sind, beispielsweise Magnetstreifen, Microchips, Aufprägungen, Bedruckungen oder dergleichen. Im Falle eines Identitätsdokuments im Format ID-3 kann der erfindungsgemäße Datenträger eine Datenseite bilden, die in das mehrseitige Identitätsdokument eingebracht ist.The card-shaped data carriers according to the invention are preferably designed in accordance with ISO / IEC7810 as identity documents in the ID-1, ID-2 or ID-3 format and can in this respect provide all other security features and functions that are customary for such identity documents, for example magnetic strips, microchips, embossings, Printing or the like. In the case of an identity document in the ID-3 format, the data carrier according to the invention can form a data page that is incorporated into the multi-page identity document.

Figur 1 zeigt den Kartenkörper 1 eines nicht-erfindungsgemäßen kartenförmigen Datenträgers bzw. Identitätsdokuments in Schnittansicht, bestehend aus zwei transparenten Deckschichten 4 sowie einer dazwischen liegenden Streifenfolienschicht 3 mit streifenförmigen, transparenten Bereichen 3a und streifenförmigen, im wesentlichen opaken Bereichen 3b sowie eines Hologrammstreifens 2. Figure 1 shows the card body 1 of a card-shaped data carrier or identity document not according to the invention in a sectional view, consisting of two transparent cover layers 4 and an intervening strip film layer 3 with strip-shaped, transparent areas 3a and strip-shaped, essentially opaque areas 3b as well as a hologram strip 2.

Die in den Figuren 1, 2a sowie 3 bis 5 gezeigte Schnittansicht durch den Kartenkörper 1 des Datenträgers verläuft entlang des Hologrammstreifens 2, der, wie anhand Figur 2b ersichtlich, in eine Hologrammfolienschicht 20 integriert ist, die außerhalb dem Hologrammstreifen 2 transparent ist. Das Format der Hologrammfolienschicht 20, also deren flächige Ausdehnung, entspricht hierbei derjenigen des Kartenkörpers 1 sowie dem Format der weiteren Schichten, insbesondere der Streifenfolienschicht 3 gemäß den Figuren 1, 3 und 5 bzw. den Streifenfolienschichten 31, 32 gemäß den Figuren 2 und 4. Die Hologrammfolienschicht 20 kann prinzipiell mehrere Hologrammstreifen 2 aufweisen, die auch nicht notwendigerweise parallel verlaufen müssen, sondern zum Beispiel spitze Winkel einschließen können, um durch weitere optische Effekte die Sicherheit des Datenträgers zu erhöhen.The ones in the Figures 1, 2a and the sectional view shown in FIGS. 3 to 5 through the card body 1 of the data carrier runs along the hologram strip 2, which, as shown in FIG Figure 2b can be seen, is integrated into a hologram film layer 20 which is transparent outside the hologram strip 2. The format of the hologram film layer 20, that is, its two-dimensional extent, corresponds to that of the card body 1 and the format of the other layers, in particular the strip film layer 3 according to FIGS. 1, 3 and 5 or the strip film layers 31, 32 according to FIGS Figures 2 and 4th . The hologram film layer 20 can in principle have several hologram strips 2, which also do not necessarily run parallel but can include acute angles, for example, in order to increase the security of the data carrier through additional optical effects.

Der Hologrammstreifen 2 bildet einen Hologramm-Sicherheitsfaden des Datenträgers. Er ist auf die Hologrammfolienschicht 20 in Form von diffraktiven Oberflächenelementen aufgebracht bzw. in diese eingebracht und kann darüber hinaus auch Demetallisierungen und weitere, gegebenenfalls versteckte Sicherheitsmerkmale aufweisen, beispielsweise maschinenlesbare Merkmale, die verschiedene physikalische Effekte ausnutzen wie zum Beispiel Magnetismus, elektrische Leitfähigkeit, Fluoreszenz oder Lumineszenz, oder Absorptions- bzw. Reflexionseigenschaften unter UV-Licht, polarisiertem Licht oder Laserlicht. Aus dem gleichen Grund kann auch die Hologrammfolienschicht 20 weitere Sicherheitsmerkmale aufweisen, die entweder in dem transparenten Bereich der Hologrammfolienschicht 20 angeordnet sein können oder den Hologrammstreifen 2 überlappend oder kreuzen.The hologram strip 2 forms a hologram security thread of the data carrier. It is applied to or incorporated into the hologram film layer 20 in the form of diffractive surface elements and can also have demetallization and other, possibly hidden, security features, for example machine-readable features that use various physical effects such as magnetism, electrical conductivity, fluorescence or Luminescence, or absorption or reflection properties under UV light, polarized light or laser light. For the same reason, the hologram film layer 20 can also have further security features, which can either be arranged in the transparent area of the hologram film layer 20 or overlap or cross the hologram strips 2.

Der in dem Figuren dargestellte kartenförmige Datenträger ist im Format ID-1 gemäß ISO/IEC 180 ausgebildet und repräsentiert eine Bankkarte, Kreditkarte, Debitkarte, einen Führerschein, einen elektronischen Personalausweis oder dergleichen. In diesem Zusammenhang kann der Kartenkörper 1 mit weiteren Sicherheits- oder Identitätsmerkmalen ausgestattet sein, beispielsweise mit Mikrochips, die kontaktlos oder kontaktbehaftet auslesbar sind, Magnetstreifen, biometrischen Merkmalen oder graphische Elementen, wie zum Beispiel Sicherheitsaufdrucken oder dergleichen.The card-shaped data carrier shown in the figures is designed in the ID-1 format in accordance with ISO / IEC 180 and represents a bank card, credit card, debit card, driver's license, electronic identity card or the like. In this context, the card body 1 can be equipped with further security or identity features, for example with microchips that can be read out contactlessly or with contact, magnetic strips, biometric features or graphic elements such as security imprints or the like.

Die Schichtanordnung gemäß Figur 1 erzeugt verschiedene optische Effekte, abhängig davon, ob der Datenträger von der Oberseite O aus betrachtet wird - also durch die obere transparente Deckschicht 4 hindurch auf die Streifenfolienschicht 3 und weiter auf den Hologrammstreifen 2 - oder ob sie von der Unterseite U aus durch die untere Deckschicht 4 direkt auf den Hologrammstreifen 2 betrachtet wird. Von der Oberseite O aus betrachtet ist der Hologrammstreifen 2 im Auflicht durch die transparenten Bereiche 3a der Streifenfolienschicht 3 sichtbar, während er durch die im Wesentlichen opaken Bereiche 3b verdeckt wird. Es entsteht also der Eindruck eines abschnittsweise sichtbaren Hologramm-Sicherheitsfadens. Von der Unterseite U aus betrachtet ist der Hologrammstreifen 2 im Auflicht jedoch vollständig sichtbar.The layer arrangement according to Figure 1 produces various optical effects, depending on whether the data carrier is viewed from the top O - that is, through the upper transparent cover layer 4 onto the strip film layer 3 and further onto the hologram strip 2 - or whether it is viewed from the Underside U from is viewed through the lower cover layer 4 directly onto the hologram strip 2. Viewed from the top O, the hologram strip 2 is visible in incident light through the transparent areas 3a of the strip film layer 3, while it is covered by the essentially opaque areas 3b. This creates the impression of a hologram security thread that is visible in sections. Viewed from the bottom U, however, the hologram strip 2 is completely visible in incident light.

Im Durchlicht ergibt sich ein differenzierteres Bild, nämlich von der Oberseite O aus betrachtet ist der Hologrammstreifen 2 durch die transparenten Bereiche 3a hindurch deutlich sichtbar und durch die im Wesentlichen opaken Bereiche 3b hindurch lediglich schattenartig sichtbar. Es ergeben sich im Durchlicht also deutliche Unterschiede hinsichtlich der Sichtbarkeit des Hologrammstreifens 2, und zwar einerseits aufgrund der optischen Dichte bzw. Transmissionseigenschaften der im wesentlichen opaken Bereiche 3b und andererseits aufgrund eines lichtstreuenden bzw. lichtbrechenden Effekts der im wesentlichen opaken Bereiche 3b, der als diffuser Schatteneffekt wahrnehmbar ist.In transmitted light, a more differentiated image results, namely, viewed from the top O, the hologram strip 2 is clearly visible through the transparent areas 3a and only visible in a shadow-like manner through the essentially opaque areas 3b. In transmitted light there are therefore significant differences with regard to the visibility of the hologram strip 2, on the one hand due to the optical density or transmission properties of the essentially opaque areas 3b and on the other hand due to a light-scattering or light-refracting effect of the essentially opaque areas 3b, which is more diffuse Shadow effect is noticeable.

Im Durchlicht von der Unterseite U des Kartenkörpers 1 aus gesehen ist der Hologrammstreifen 2 wiederum vollständig sichtbar, da die die Unterseite bildende transparente Deckschicht 4 die Sichtbarkeit auf den Hologrammstreifen 2 nicht bzw. lediglich vernachlässigbar beeinträchtigt.In transmitted light from the underside U of the card body 1, the hologram strip 2 is again completely visible, since the transparent cover layer 4 forming the underside does not impair the visibility of the hologram strip 2 or only negligibly affects it.

Figur 2a zeigt ein Beispiel eines nicht-erfindungsgemäßen Datenträgers, bei dem der Hologrammstreifen 2 von zwei Streifenfolienschichten 31, 32 flächig eingeschlossen wird. Hierbei ist der Hologrammstreifen 2 im Auflicht sowohl von der Oberseite O als auch von der Unterseite U aus betrachtet abschnittsweise sichtbar, nämlich einerseits durch die transparenten Bereiche 31a der Streifenfolienschicht 31 hindurch und andererseits durch die transparenten Bereiche 32a der Streifenschicht 32 hindurch. Figure 2a shows an example of a data carrier not according to the invention, in which the hologram strip 2 is enclosed over a large area by two strip film layers 31, 32. Here, the hologram strip 2 is visible in incident light both from the top O and from the bottom U in sections, namely on the one hand through the transparent regions 31a of the strip film layer 31 and on the other hand through the transparent regions 32a of the strip layer 32.

Figur 2b illustriert die Schichtfolge des Kartenkörpers 1 gemäß Figur 2a in Draufsicht. Danach wird über der Hologrammfolienschicht 20 die Streifenfolienschicht 31 angeordnet und darunter die Streifenfolienschicht 32 (symbolisiert durch die Pluszeichen). Im Auflicht ergibt sich aufgrund der Wechselwirkung zwischen der Hologrammfolienschicht 20 und der Streifenfolienschicht 31 bzw. der Streifenfolienschicht 32 (symbolisiert durch die Gleichzeichen) von der Oberseite O des Datenträgers aus betrachtet die Ansicht 33 und von der Unterseite U aus betrachtet die Ansicht 34. Bei beiden Auflicht-Ansichten 33, 34 ist der Hologrammstreifen 2 lediglich alternierend, abschnittsweise durch die jeweiligen transparenten Streifen 31a, 32a hindurch sichtbar, während er abschnittsweise von den im Wesentlichen opaken Streifen 31b, 32b (strichliniert dargestellt) bedeckt und dort nicht sichtbar ist. Figure 2b illustrates the sequence of layers of the card body 1 according to FIG Figure 2a in plan view. Then the strip film layer 31 is arranged over the hologram film layer 20 and the strip film layer 32 underneath (symbolized by the plus signs). In incident light, due to the interaction between the hologram film layer 20 and the strip film layer 31 or the strip film layer 32 (symbolized by the equals), when viewed from the upper side O of the data carrier, the view 33 and when viewed from the lower side U from the view 34 In incident light views 33, 34, the hologram strip 2 is only visible alternately, in sections through the respective transparent strips 31a, 32a, while in sections it is covered by the essentially opaque strips 31b, 32b (shown in dashed lines) and is not visible there.

Die Ausrichtung des Hologrammstreifens 2 in der Hologrammfolienschicht 20 einerseits und die Ausrichtung der streifenförmigen Bereiche 31a, 31b, 32a, 32b der Streifenfolienschichten 31, 32 andererseits ist vorzugsweise senkrecht zueinander, so dass der in Figur 2b in horizontaler Richtung verlaufende Hologrammstreifen 2 durch die parallelen, in vertikaler Richtung verlaufenden im Wesentlichen opaken Bereiche 31b, 32b abschnittsweise verdeckt wird. Der Winkel, den der Hologrammstreifen 2 und die streifenförmigen Bereiche 31a, 31b, 32a, 32b einschließen, kann beliebig weit von dem dargestellten rechten Winkel abweichen, solange der Hologrammstreifen 2 durch die transparenten Bereiche 31a, 32a, hindurch mehrfach abschnittsweise sichtbar ist und durch die im Wesentlichen opaken Bereiche 31b, 32b mehrfach abschnittsweise verdeckt wird.The alignment of the hologram strip 2 in the hologram film layer 20 on the one hand and the alignment of the strip-shaped regions 31a, 31b, 32a, 32b of the strip film layers 31, 32 on the other hand are preferably perpendicular to one another, so that the in Figure 2b Hologram strips 2 running in the horizontal direction are covered in sections by the parallel, substantially opaque regions 31b, 32b running in the vertical direction. The angle enclosed by the hologram strip 2 and the strip-shaped areas 31a, 31b, 32a, 32b can deviate as far as desired from the illustrated right angle, as long as the hologram strip 2 is visible several times in sections through the transparent areas 31a, 32a and through the essentially opaque areas 31b, 32b is covered several times in sections.

Wie aus den Figuren 2a und 2b ersichtlich, sind die beiden Streifenfolienschichten 31, 32 derart relativ zueinander angeordnet, dass jeweils die transparenten Bereiche 31a, 32a jeder Streifenfolienschicht 31, 32 möglichst genau über bzw. unter den im wesentlichen opaken Bereichen 32b, 31b der jeweils anderen Streifenfolienschicht 32, 31 liegen. Vorzugsweise ist die Ausrichtung der streifenförmigen Bereiche 31a zu den streifenförmigen Bereichen 32b bzw. die Ausrichtung der streifenförmigen Bereiche 31b zu den streifenförmigen Bereichen 32a möglichst registergenau, so dass der Hologrammstreifen 2 an jeder Stelle des Kartenkörpers 1 entweder von der Oberseite O oder von der Unterseite U aus sichtbar ist.As from the Figures 2a and 2b As can be seen, the two strip film layers 31, 32 are arranged relative to one another in such a way that the transparent areas 31a, 32a of each strip film layer 31, 32 lie as precisely as possible above or below the essentially opaque areas 32b, 31b of the respective other strip film layer 32, 31. The alignment of the strip-shaped areas 31a to the strip-shaped areas 32b or the alignment of the strip-shaped areas 31b to the strip-shaped areas 32a is preferably as accurate as possible, so that the hologram stripe 2 can be seen from the top O or from the bottom U at every point on the card body 1 is visible from.

Der sich daraus ergebende optische Effekt ist derjenige eines alternierend zwischen Oberseite O und Unterseite U hin- und herwechselnden Hologramm-Sicherheitsfadens, der aufgrund der registergenauen Anordnung der Streifenfolienschichten 31, 32 für Fälscher besonders schwer zu reproduzieren ist.The resulting optical effect is that of a hologram security thread alternating between the upper side O and the lower side U, which is particularly difficult for counterfeiters to reproduce due to the precise register arrangement of the strip film layers 31, 32.

Im Durchlicht ist der Hologrammstreifen 2 gemäß der Ausführungsform nach Figur 2a auf beiden Seiten durch die jeweiligen transparenten Bereiche 31a, 32a hindurch deutlich sichtbar und durch die im Wesentlichen opaken Bereiche 31b, 32b hindurch lediglich schattenartig sichtbar. Der auf der Oberseite O des Kartenkörpers 1 gemäß Figur 1 wahrnehmbare Effekt ist somit bei dem Kartenkörper 1 gemäß Figur 2a sowohl von der Oberseite O als auch von der Unterseite U aus wahrnehmbar.The hologram strip 2 according to the embodiment according to FIG Figure 2a clearly visible on both sides through the respective transparent areas 31a, 32a and only visible in shadow-like fashion through the essentially opaque areas 31b, 32b. The on the top O of the card body 1 according to Figure 1 perceptible effect is thus in the card body 1 according to Figure 2a perceptible both from the upper side O and from the lower side U.

Figur 3 zeigt ein weiteres Beispiel eines Datenträgers, bei dem zwischen den transparenten Deckschichten 4 unterhalb des Hologrammstreifens 2 eine im Wesentlichen opake Schicht 5 angeordnet ist, so dass sich von der Oberseite O des Kartenkörpers 1 aus betrachtet im Auflicht der gleiche optische Effekt ergibt, wie bei der Ausführungsform nach Figur 1, während von der Unterseite U aus betrachtet der Hologrammstreifen 2 im Auflicht nicht sichtbar ist. Im Durchlicht wiederum ist der Hologrammstreifen 2 von der Unterseite U aus betrachtet durchgängig schattenartig sichtbar. Figure 3 shows a further example of a data carrier in which a substantially opaque layer 5 is arranged between the transparent cover layers 4 below the hologram strip 2, so that it extends from the top O of the card body 1 when viewed in reflected light results in the same optical effect as in the embodiment according to FIG Figure 1 , while the hologram strip 2 is not visible in incident light when viewed from the underside U. In the transmitted light, in turn, the hologram strip 2, viewed from the underside U, is continuously visible like a shadow.

Figur 4 zeigt die Schichtanordnung eines kartenförmigen Datenträgers gemäß der Erfindung. Hierbei ist in den Kartenkörper 1 zwischen den beiden Hologrammstreifen 21, 22, die jeweils innerhalb einer separaten Hologrammfolienschicht 20 vorliegen, eine im Wesentlichen opake Schicht 5 eingebracht. Zwischen jedem der beiden Hologrammstreifen 21, 22 und der entsprechenden, die Ober- O bzw. Unterseite U des Kartenkörpers 1 bildenden, transparenten Deckschicht 4 befindet sich jeweils eine Streifenfolienschicht 31, 32, die den jeweiligen Hologrammstreifen 21, 22 in Richtung der betreffenden Seite des Kartenkörpers 1 hin bedeckt. Figure 4 shows the layer arrangement of a card-shaped data carrier according to the invention. Here, an essentially opaque layer 5 is introduced into the card body 1 between the two hologram strips 21, 22, which are each present within a separate hologram film layer 20. Between each of the two hologram strips 21, 22 and the corresponding, the top O or bottom U of the card body 1 forming, transparent cover layer 4 is a respective strip film layer 31, 32, which the respective hologram strips 21, 22 in the direction of the relevant side of the Card body 1 covered.

Sowohl von der Oberseite O als auch von der Unterseite U des Kartenkörpers 1 aus gesehen erscheint der jeweilige Hologrammstreifen 21, 22 im Auflicht abschnittsweise unterbrochen, da er lediglich durch die transparenten Bereiche 31a, 32a hindurch sichtbar ist, während die im wesentlichen opaken Bereiche 31b, 32b die Sicht auf den Hologrammstreifen 21, 22 verdecken. Je nachdem, wie die transparenten Bereiche 31a, 32a und die im Wesentlichen opaken Bereiche 31b, 32b der beiden Streifenfolienschichten 31, 32 zueinander ausgerichtet sind, können sich im Durchlicht weitere Effekte ergeben. Falls, wie in Figur 4 dargestellt, die transparenten Bereiche 31a, 32a der einen Streifenfolienschicht 31, 32 und im Wesentliche opaken Bereiche 31b, 32b der anderen Streifenfolienschicht 32, 31 übereinander liegen, kann der betreffende Hologrammstreifen 21, 22 im Durchlicht von beiden Seiten des Kartenkörpers aus gesehen durch die betreffenden, im Wesentlichen opake Bereiche 31b, 32b hindurch schattenartig sichtbar sein, wenn die Transmissionseigenschaften der im Wesentlichen opaken Schicht 5 und der jeweiligen, im Wesentlichen opake Bereiche 31b, 32b entsprechend aufeinander abgestimmt sind.When viewed from the top O as well as from the bottom U of the card body 1, the respective hologram strip 21, 22 appears interrupted in the incident light, since it is only visible through the transparent areas 31a, 32a, while the essentially opaque areas 31b, 32b cover the view of the hologram strip 21, 22. Depending on how the transparent areas 31a, 32a and the essentially opaque areas 31b, 32b of the two strip film layers 31, 32 are aligned with one another, further effects can result in transmitted light. If, as in Figure 4 shown, the transparent areas 31a, 32a of one strip film layer 31, 32 and essentially opaque areas 31b, 32b of the other strip film layer 32, 31 are superimposed, the relevant hologram strips 21, 22 can be seen in transmitted light from both sides of the card body viewed through the relevant, essentially opaque areas 31b, 32b, can be seen in a shadow-like manner if the transmission properties of the essentially opaque layer 5 and the respective, essentially opaque areas 31b, 32b are correspondingly matched to one another.

Figur 5 schließlich zeigt eine Variante der Schichtanordnung gemäß Figur 3, bei der die Deckfolienschichten 4 jeweils aus mehreren Folienschichten 41, 42 bestehen. Auch die im Wesentlichen opake Folienschicht, wie sie in den nicht-erfindungsgemäßen Schichtanordnungen gemäß Figur 3 oder Figur 4 eingesetzt wird, besteht hier aus mehreren im Wesentlichen opaken Folienschichten 50, so dass die Transmissionseigenschaften des im Wesentlichen opaken Folienstapels 50 an die erwünschten optischen Effekte im Durchlicht angepasst werden können. Figure 5 finally shows a variant of the layer arrangement according to FIG Figure 3 , in which the cover film layers 4 each consist of several film layers 41, 42. Also the essentially opaque film layer as shown in the layer arrangements not according to the invention Figure 3 or Figure 4 is used, consists of several essentially opaque film layers 50, so that the transmission properties of the essentially opaque film stack 50 can be adapted to the desired optical effects in transmitted light.

Ebenso, wie bei den im Wesentlichen opaken Bereichen 3b, 31b, 32b der Streifenfolienschichten 3, 31, 32 weisen auch die im Wesentlichen opaken Schichten 5, 50 gemäß den Figuren 3, 4 und 5 im Durchlicht eine wahrnehmbare Transluzenz und lichtstreuende Eigenschaften auf. Durch Variation der Dicke einzelner im Wesentlichen opaken Schichten 5 oder Verwendung von mehreren im Wesentlichen opaken Schichten 50 können bestimmte, im Durchlicht wahrnehmbare Transmissionseigenschaften erreicht werden.As with the essentially opaque areas 3b, 31b, 32b of the strip film layers 3, 31, 32, the essentially opaque layers 5, 50 according to FIGS Figures 3, 4 and 5 a perceptible translucency and light-scattering properties in transmitted light. By varying the thickness of individual essentially opaque layers 5 or using a plurality of essentially opaque layers 50, certain transmission properties that can be perceived in transmitted light can be achieved.

Die beschriebenen Folienschichten 20, 3, 31, 32, 4, 41, 42, 5, 50 sind vorzugsweise aus Kunststoff gefertigt. Daneben können in den Kartenkörper aber auch Bereiche oder Schichten anderen Materialien eingebracht werden, beispielsweise aus Papier, sofern dies für die Fälschungssicherheit oder Verwendung des Datenträgers als Identitätskarte zweckmäßig ist. Darüber hinaus ist jede beliebige weitere Ausgestaltung des erfindungsgemäßen Datenträgers möglich, die dessen Verwendung als Identitätskarte erfordert.The film layers 20, 3, 31, 32, 4, 41, 42, 5, 50 described are preferably made of plastic. In addition, areas or layers of other materials can also be incorporated into the card body, for example made of paper, provided this is expedient for protection against forgery or for using the data carrier as an identity card. In addition, any further configuration of the data carrier according to the invention that requires its use as an identity card is possible.
