Abstract

A forgery-proof information carrier comprises an insert (1) having a passport photo (7), data about the owner and other security features, and plastics films (5, 6) which are joined in an undetachable manner to the insert (1), and is distinguished in that a metal mask (2) is provided as an edge protection at least in the region of the edges of the information carrier. In a further development to increase the security against forgeries, the metal mask (2) may be inwardly provided with irregular edges (3) or with openings (4).

Description

Die Erfindung betrifft einen fälschungssicheren Informationsträger, z.B. eine Ausweiskarte (ID-Karte), einen Bankausweis oder eine Berechtigungskarte, der zwischen zwei Kunststoffolien eine Einlage mit Paßbild, den Daten des Eigentümers und verschiedenen Sicherheitmerkmalen in unlösbarer Verbindung enthält.The invention relates to a tamper-proof information carrier, e.g. an identification card (ID card), a bank card or an authorization card that contains an insert with a passport picture, the owner's data and various security features in an inseparable connection between two plastic films.

Es ist bekannt, Dokumente, wie ID-Karten-Einlage mit Paßbildern, Unterschriften, Fingerabdrücken zu versehen und die Dokumente dann zwischen Folien einzuschweißen.It is known to provide documents such as ID card inserts with passport photos, signatures, fingerprints and then to weld the documents between foils.

Um ein Austauschen eingelegter Paßbilder zu verhindern, kann die Einlage aus einem Stück speziellen Photopapiers hergestellt werden, auf dessen Schichten die Daten des Karteninhabers und das Paßbild aufbelichtet und entwickelt werden. Die Einlage kann dann noch mit zusätzlichen Identifikationsmerkmalen, z.B. mit Linien- oder Rasterdrucken versehen werden und wird schließlich zwischen Folien eingeschweißt.To prevent the exchange of inserted passport photos, the insert can be made from a piece of special photo paper, on the layers of which the cardholder data and the passport photo are exposed and developed. The insert can then be provided with additional identification features, e.g. with line or raster prints and is finally sealed between foils.

Aus der DE-A 2 631 246 ist es bekannt, Dokumente wie Ausweiskarten, Berechtigungskarten und dergleichen mit Dauermagneten, Magnetblättern, Magnetbändern oder Metallblättern zu versehen. Diese Einrichtungen können zum Öffnen eines magnetischen Schlosses oder zur Betätigung eines Schalters verwendet werden. In der US-PS 4 066 873 wird die Einlage von Magnetstreifen, die kodierte magnetische Informationen enthalten, in solche Dokumente beschrieben, wobei gleichzeitig ein aufgedruckter Binärcode zur optischen Abfrage vorgesehen ist. Aus der US-A 4 330 350 ist ein Informationstrager mit einer Einlage, deren beide Seiten mit einer Kunststoffolie verbunden sind und einer entlang der Kanten angeordneten Maske bekannt.From DE-A 2 631 246 it is known to provide documents such as identity cards, authorization cards and the like with permanent magnets, magnetic sheets, magnetic tapes or metal sheets. These devices can be used to open a magnetic lock or to operate a switch. US Pat. No. 4,066,873 describes the insertion of magnetic strips which contain encoded magnetic information into such documents, a printed binary code for optical interrogation being provided at the same time. From US-A 4 330 350 an information carrier with an insert, the two sides of which are connected with a plastic film and a mask arranged along the edges, is known.

Diese und eine Vielzahl ähnlicher bekannter Ausführungsarten von Informationsträgern haben den Nachteil, daß ihre Außenkanten ungenügend geschützt sind, so daß sie durch mechanische Beanspruchungen (z.B. bei Verwendung zum Abkratzen von Eis an Autoscheiben) leicht beschädigt werden. Dies kann zur Unbrauchbarkeit des Informationsträgers führen, insbesondere dann, wenn die Informationen dazu bestimmt sind maschinell gelesen zu werden und der Abstand der Informationen zum Kartenrand durch Beanspruchung der Kanten geändert worden ist.This and a large number of similar known types of information carriers have the disadvantage that their outer edges are insufficiently protected so that they are easily damaged by mechanical stresses (e.g. when used to scrape ice off car windows). This can lead to the information carrier being unusable, in particular if the information is intended to be read by machine and the distance of the information from the edge of the card has been changed by stressing the edges.

Aus der US-A 3 731 085 und aus der FR-A 2 170 768 sind auch schon Ausweiskarten und dergleichen bekannt, bei denen der Datenträger aus Metall besteht und beidseitig beschichtet ist.From US-A 3 731 085 and from FR-A 2 170 768 identity cards and the like are already known in which the data carrier consists of metal and is coated on both sides.

Der Erfindung liegt die Aufgabe zugrunde, einen Informationsträger zu entwickeln, der ein hohes Maß an Sicherheit gegen Fälschungen bietet und dessen Kantenstabilität so verbessert ist, daß auch bei starker mechanischer Beanspruchung der Kanten die Maschinenlesbarkeit der Daten in den verschiedenen Ausweislesegeräten gewährleistet bleibt.The invention has for its object to develop an information carrier that offers a high degree of security against counterfeiting and whose edge stability is improved so that the machine readability of the data in the various card readers is guaranteed even with strong mechanical stress on the edges.

Es wurde ein fälschungssicherer Informationsträger gefunden, bestehend aus einer Einlage mit Paßbild, den Daten des Eigentümers und weiteren Sicherheitsmerkmalen, deren beide Seiten mit Kunststoffolien unlösbar verbunden sind und aus einer entlang der Kanten des Informationsträgers angeordneten rahmenfÖrmigen Maske, die nach außen bündig mit den Kanten des Informationsträgers abschließt, dadurch gekennzeichnet, daß die Maske aus Metall besteht.A forgery-proof information carrier was found, consisting of an insert with a passport picture, the data of the owner and other security features, the two sides of which are inextricably linked with plastic films, and a frame-shaped mask arranged along the edges of the information carrier, which is flush with the edges of the Closes information carrier, characterized in that the mask is made of metal.

Die Metallmaske schützt die Kanten des Informationsträgers in überraschend einfacher Weise vor Abnutzung, da das Metall der Metallmaske einer mechanischen Beanspruchung wesentlich mehr Widerstand leistet als die bisher gebräuchlichen Kunststoff-Kanten der Informationsträger. Die Metallkante gewährleistet eine sichere Anlage des Informationsträgers im Lesegerät und damit die störungsfreie Lesbarkeit der Daten mit dem Ausweislesegerät. Zudem ist der Ausweis durch die Metallmaske stabiler und wie weiter unten gezeigt wird auch sicherer gegen Fälschungen.The metal mask protects the edges of the information carrier from wear in a surprisingly simple manner, since the metal of the metal mask provides mechanical resistance to much greater resistance than the previously used plastic edges of the information carriers. The metal edge ensures that the information carrier is securely positioned in the reader and thus that the data can be read without interference using the card reader. In addition, the ID is more stable thanks to the metal mask and, as shown below, is also more secure against counterfeiting.

Die Metallmaske kann aus jedem beliebigen Metall hergestellt werden. Gute Ergebnisse bezüglich der mechanischen Festigkeit zeigt eine Stahlblechmaske, die auch preisliche Vorteile hat. Die Dicke der Maske wird im allgemeinen der der Einlage vergleichbar sein. Sie kann in bestimmten Anwendungsformen aber auch deutlich geringer sein. Soll die Fälschung des Informationsträgers erschwert werden, so können auch seltenere Metalle oder Metall-Legierungen als Metallmaske verwendet werden. Die Metallmaske kann auch als weiteres Sicherheitsmerkmal verwendet werden, wenn sie bestimmte magnetische oder elektrische Eigenschaften aufweist, z.B. eine bestimmte Koerzitivkraft, eine bestimmte Kapazität oder einen bestimmten Widerstand.The metal mask can be made from any metal. A sheet steel mask shows good results in terms of mechanical strength, which also has price advantages. The thickness of the mask will generally be comparable to that of the insert. However, it can also be significantly lower in certain application forms. If the counterfeiting of the information carrier is to be made more difficult, rare metals or metal alloys can also be used as a metal mask. The metal mask can also be used as a further security feature if it has certain magnetic or electrical properties, e.g. a certain coercive force, a certain capacity or a certain resistance.

In einer vorteilhaften Weiterentwicklung ist die Metallmaske an den innen liegenden Kanten gezackt oder unregelmäßig geformt, wodurch eine Öffnung des verschweißten oder verklebten Informationsträgers zu Fälschungszwecken erheblich erschwert wird.In an advantageous further development, the metal mask is serrated or irregularly shaped on the inner edges, which makes it considerably more difficult to open the welded or glued information carrier for counterfeiting purposes.

Eine andere Weiterentwicklung der Metallmaske zeichnet sich dadurch aus, daß die Metallmaske mit Bohrungen versehen ist, durch die die obere Kunststoffolie mit der unteren Kunststoffolie durch Verkleben oder Verschweißen verbunden ist. Der Verbund der Einlage, der Metallmaske und der beiden Schutzfolien wird dadurch verbessert und ein Fälschungsversuch weiter erschwert.Another further development of the metal mask is characterized in that the metal mask is provided with holes through which the upper plastic film is connected to the lower plastic film by gluing or welding. The bond between the insert, the metal mask and the two protective foils is thereby improved and an attempt at forgery is made even more difficult.

Im folgenden werden Ausführungsformen der Erfindung anhand von Zeichnungen näher beschrieben. Es zeigt:

  • Fig. 1 eine Draufsicht auf einen Informationsträger mit Metallmaske,
  • Fig. 2 einen Querschnitt durch den Informationsträger nach Fig. 1,
  • Fig. 3 spezielle Ausführungsformen der Metallmaske in einem Informationsträger,
  • Fig. 4 ein Querschnitt mit einer eingepreßten Metallmaske.
In the following, embodiments of the invention are described in more detail with reference to drawings. It shows:
  • 1 is a plan view of an information carrier with a metal mask,
  • 2 shows a cross section through the information carrier according to FIG. 1,
  • 3 special embodiments of the metal mask in an information carrier,
  • Fig. 4 is a cross section with a pressed Metal mask.

Fig. 1 zeigt in einer Draufsicht einen Informationsträger, dessen Einlage 1 ein Feld 7 für ein Paßbild oder eine Photographie enthält und auf dem Felder 8 für persönliche Daten des Karteninhabers angeordnet sind und entlang einer Kante des Informationsträgers ein Feld 9 vorgesehen ist. Das Einlageblatt ist von einer Metallmaske 2 umgeben und zusammen mit der Maske zwischen Kunststoffolien 5, 6 (Fig. 2) eingeschweißt oder eingeklebt.1 shows a top view of an information carrier, the insert 1 of which contains a field 7 for a passport photograph or a photograph and on which fields 8 for personal data of the cardholder are arranged and a field 9 is provided along an edge of the information carrier. The insert sheet is surrounded by a metal mask 2 and welded or glued together with the mask between plastic films 5, 6 (FIG. 2).

Fig. 2 zeigt einen Querschnitt durch den Informationsträger nach Fig. 1, wobei dieFig. 2 shows a cross section through the information carrier according to Fig. 1, the

Materialdicken vergrößert dargestellt sind. Die Einlage 1 liegt zwischen Kunststoffolien 5 und 6 und ist unlösbar mit diesen verbunden. Rund um die Einlage 1 ist eine Metallmaske 2 angeordnet, die die Kanten des Informationsträgers vor mechanischer Abnutzung schützt und garantiert, daß der Abstand von der Kante 10 zu dem Feld 9 für maschinenlesbare Daten praktisch unverändert bleibt, selbst wenn die Ausweiskarte zweckentfremdet für Arbeiten verwendet wird, für die sie nicht vorgesehen ist. Die Metallmaske 2 ist ebenfalls zwischen den Folien 5 eingelegt und unlösbar mit diesen verbunden, so daß der Informationsträger in vorteilhafter Weise eine stabile feste Einheit mit gleicher Dicke über die gesamte Oberfläche bildet. Es sind natürlich auch Ausführungsformen möglich, bei denen die Einlage 1 die gleiche Größe wie der Informationsträger besitzt und die Metallmaske in die Einlage 1 eingelassen ist oder auf diese aufgeklebt ist.Material thicknesses are shown enlarged. The insert 1 is between plastic films 5 and 6 and is permanently connected to them. A metal mask 2 is arranged around the insert 1, which protects the edges of the information carrier from mechanical wear and guarantees that the distance from the edge 10 to the field 9 for machine-readable data remains practically unchanged, even if the identification card is used for purposes other than the intended purpose for which it is not intended. The metal mask 2 is also inserted between the foils 5 and permanently connected to them, so that the information carrier advantageously forms a stable, solid unit with the same thickness over the entire surface. Of course, embodiments are also possible in which the insert 1 has the same size as the information carrier and the metal mask is embedded in the insert 1 or is glued to it.

Fig. 3 zeigt eine vorteilhafte Weiterbildung des Informationsträgers gemäß Fig. 2 bei der die Metallmaske außer der Verfestigung der Kanten noch die Aufgabe der Erhöhung der Sicherheit gegen Fälschungen übernimmt. Wie dargestellt, hat die Metallmaske entlang der Außenkanten eine glatte Kante zum Schutz gegen mechanischen Abrieb. Die zur Einlage hin innen gelegenen Kanten der Metallmaske sind mit Zacken 3 oder unregelmäßigen Formen versehen, die in die Einlage 1 hineinragen. Die Einlage 1 kann an ihren Rändern passend zu der Metallmaske 2 ausgestanzt sein, wenn die Metallmaske 2 die gleiche Dicke wie die Einlage 1 hat (Fig. 2). Die Einlage 1 kann auch glatte Kanten besitzen und die Metallmaske 2 auf diese aufgeklebt sein. Durch Prägen des Informationsträgers unter Druck und Wärme dringen dann die Zacken 3 sowohl in die Einlage 1 als auch in die Kunststoffolie 5 (bzw. 6) ein, so daß ebenfalls eine Karte gleiche Dicke entsteht (Fig. 4), wobei die Metallmaske in zwei Schichten nämlich die Folie 5 und die Einlage 1, eingepreßt ist, so daß ein Öffnen der Karte durch Trennen der Schichten zu Fälschungszwecken nicht mehr möglich ist.FIG. 3 shows an advantageous development of the information carrier according to FIG. 2 in which the metal mask, in addition to the solidification of the edges, also takes on the task of increasing security against counterfeiting. As shown, the metal mask has a smooth edge along the outer edges to protect against mechanical abrasion. The edges of the metal mask lying towards the insert are provided with teeth 3 or irregular shapes which protrude into the insert 1. The insert 1 can be punched out at its edges to match the metal mask 2 if the metal mask 2 has the same thickness as the insert 1 (FIG. 2). The insert 1 can also have smooth edges and the metal mask 2 can be glued to it. By embossing the information carrier under pressure and heat, the prongs 3 then penetrate both into the insert 1 and into the plastic film 5 (or 6), so that a card of the same thickness is also formed (FIG. 4), the metal mask being in two Layers namely the film 5 and the insert 1 is pressed so that opening the card by separating the layers is no longer possible for counterfeiting purposes.

Eine weitere vorteilhafte Verbesserung des Informationsträgers wird dadurch erhalten, daß die Metallmaske mit Bohrungen oder Löchern 4 (Fig. 3) versehen wird. Beim Zusammenkleben oder Verschweißen der Folien 5, 6 mit der Einlage 1 und der Metallmaske 2 werden die obere Folie 5 mit der unteren Folie 6 durch diese Löcher hindurch miteinander fest verbunden. Hierdurch wird die Steifigkeit und Festigkeit des Informationsträgers erhöht und gleichzeitig eine Fälschung erheblich erschwert. Die Kombination der nach innen gerichteten Zacken 3 und den rundum angeordneten Löchern 4 in der Metallmaske erhöhen zusammen ausgeführt (wie in Fig. 3 dargestellt) in erheblichem Maße die Sicherheit des Informationsträgers gegen Fälschungsversuche.A further advantageous improvement of the information carrier is obtained in that the metal mask is provided with bores or holes 4 (FIG. 3). When the foils 5, 6 are glued or welded to the insert 1 and the metal mask 2, the upper foil 5 and the lower foil 6 are firmly connected to one another through these holes. This increases the stiffness and strength of the information carrier and at the same time makes counterfeiting considerably more difficult. The combination of the inwardly directed tines 3 and the all-round holes 4 in the metal mask, carried out together (as shown in FIG. 3) significantly increase the security of the information carrier against attempts at counterfeiting.

Zusätzlich zu diesen formbedingten Sicherheitsmerkmalen können die Eigenschaften der Metallmaske 2 zur Überprüfung der Echtheit von Informationsträgern herangezogen werden. Die Metallmaske 2 kann magnetisch sein, einen bestimmten elektrischen Widerstand besitzen, eine bestimmte elektrische Ladung aufnehmen oder aber aus einer bestimmten schwer reproduzierbaren Legierung bestehen. Die Zacken 3 und/oder Löcher 4 können bestimmte unregelmäßige Abstände voneinander haben, aus denen bei Bewegung der Karte durch ein Prüfgerät induktiv ein Code abgelesen und mit dem Prüfcode elektronisch verglichen werden kann, wobei gleichzeitig die Daten im Feld 9 gelesen werden können.In addition to these shape-related security features, the properties of the metal mask 2 can be used to check the authenticity of information carriers. The metal mask 2 can be magnetic, have a certain electrical resistance, take up a certain electrical charge or can consist of a certain alloy that is difficult to reproduce. The prongs 3 and / or holes 4 can have certain irregular distances from one another, from which a code can be read inductively when the card is moved by a test device and electronically compared with the test code, the data in field 9 being able to be read simultaneously.
