Description

Die Erfindung betrifft einen kartenförmigen Datenträger.The invention relates to a card-shaped data carrier.

Kartenförmige Datenträger, insbesondere Chipkarten werden in vielen Bereichen eingesetzt, beispielsweise als Ausweisdokumente, zum Nachweis einer Zugangsberechtigung zu einem Mobilfunknetz oder zur Durchführung von Transaktionen des bargeldlosen Zahlungsverkehrs. Eine Chipkarte weist einen Kartenkörper und einen in den Kartenkörper eingebetteten integrierten Schaltkreis auf. Die eigentliche Funktionalität der Chipkarte wird vom integrierten Schaltkreis bereitgestellt. Hierzu sind im integrierten Schaltkreis beispielsweise Daten gespeichert und Anwendungen implementiert. Der Kartenkörper dient der Handhabung der Chipkarte und kann als Träger von visuellen Informationen und von Sicherheitsmerkmalen dienen. Dabei wird in der Regel versucht, der Chipkarte über eine geeignete Gestaltung des Kartenkörpers ein attraktives Aussehen zu verleihen.Card-shaped data carriers, in particular chip cards, are used in many areas, for example as identity documents, as proof of access authorization to a mobile radio network or for carrying out transactions of cashless payment transactions. A smart card has a card body and an integrated circuit embedded in the card body. The actual functionality of the chip card is provided by the integrated circuit. For this purpose, for example, data are stored in the integrated circuit and applications implemented. The card body is used to handle the smart card and can serve as a carrier of visual information and security features. In this case, it is usually attempted to give the smart card over a suitable design of the card body an attractive appearance.

Aus der DE 101 53 260 A1 ist eine Datenträgerkarte mit einem plattenförmigen Kartenkörper aus einem durchsichtigen Kunststoffmaterial bekannt, dem fluoreszierende Farbstoffe beigegeben sind. Bei einer Bestrahlung mit Licht auf den Flachseiten der Datenträgerkarte leuchtet diese beispielsweise an ihren Kantenflächen in der Farbe des beigemischten fluoreszierenden Farbstoffs. Dieser Leuchteffekt kann bei Sicherheitsüberprüfungen einer derartigen Karte genutzt werden.From the DE 101 53 260 A1 is a data carrier card with a plate-shaped card body made of a transparent plastic material known to the fluorescent dyes are added. Upon irradiation with light on the flat sides of the data carrier card, the latter illuminates, for example, at its edge surfaces in the color of the admixed fluorescent dye. This glow effect can be used during security checks of such a card.

Aus der DE 100 48 812 A1 ist ein Verfahren zur Personalisierung von lumineszierenden Echtheitsmerkmalen auf Datenträgern bekannt. Bei diesem Verfahren wird ein lumineszierendes Echtheitsmerkmal in den Kartenverbund eingebracht oder auf den Kartenverbund aufgebracht. Anschließend wird das Echtheitsmerkmal mit einem energiereichen Strahl personalisiert. Dadurch wird die Struktur des Echtheitsmerkmals lokal so verändert, dass bei lumineszierendem Aufleuchten des Echtheitsmerkmals der durch die Personalisierung eingeschriebene Schriftzug als Negativbild erkennbar ist. Die Anregung der Lumineszenz oder Phosphoreszenz erfolgt mittels UV-Licht oder eines elektromagnetischen Felds. Unter Normalbedingungen ist das Echtheitsmerkmal nicht sichtbar.From the DE 100 48 812 A1 A method for personalizing luminescent authentication features on data carriers is known. In this method, a luminescent authenticity feature is introduced into the card composite or applied to the card composite. Subsequently, the authenticity feature is personalized with a high-energy beam. As a result, the structure of the authenticity feature is locally changed so that in the case of luminescent illumination of the authenticity feature, the inscription inscribed by the personalization can be recognized as a negative image. The excitation of the luminescence or phosphorescence takes place by means of UV light or an electromagnetic field. Under normal conditions the authenticity feature is not visible.

Aus der US-PS 3,604,901 ist eine Informationskarte bekannt, die als eine Laminatstruktur aus drei Lagen ausgebildet ist. Eine untere Lage aus einem opaken Material weist Löcher auf, die eine codierte Information darstellen. Eine mittlere Lage aus einem transluzenten Material füllt die Löcher aus. Eine obere Lage aus einem transparenten Material schützt die mittlere Lage.From the U.S. Patent 3,604,901 For example, an information card is known which is formed as a laminate structure of three layers. A lower layer of opaque material has holes that represent coded information. A middle layer of translucent material fills the holes. An upper layer of transparent material protects the middle layer.

Aus der WO 93/ 23826 A1 ist eine Chipkarte bekannt, bei der ein lichtsammelnder Kunststoff zur Weiterleitung von Lichtsignalen zu Empfangsdioden verwendet wird. Die Lichtsignale werden durch optische Schaltelemente beeinflusst. Mit den Schaltelementen kann beispielsweise ein Geheimcode eingegeben werden. Die Einstrahlung des Lichts kann aus der Umgebung oder mittels einer integrierten Sendediode erfolgen.From the WO 93/23826 A1 a chip card is known in which a light-collecting plastic is used for the transmission of light signals to receiving diodes. The light signals are influenced by optical switching elements. With the switching elements, for example, a secret code can be entered. The irradiation of the light can be done from the environment or by means of an integrated transmitter diode.

US 4,710,614 zeigt einen Datenträger mit einer optischen Faser, die sich zwischen zwei Längsseiten des Datenträgers erstreckt. Licht wird von einer Hauptfläche des Datenträgers in die optische Faser eingekoppelt und von der optischen Faser zu den beiden Längsseiten des Datenträgers geleitet. US 4,710,614 shows a data carrier with an optical fiber, which extends between two longitudinal sides of the data carrier. Light is coupled from a major surface of the data carrier into the optical fiber and directed from the optical fiber to the two longitudinal sides of the data carrier.

Der Erfindung liegt die Aufgabe zugrunde, den Aufbau eines Kartenkörpers eines kartenförmigen Datenträgers so zu gestalten, dass ein oder mehrere graphische Elemente des Kartenkörpers visuell gut hervorgehoben werden.The invention has for its object to make the structure of a card body of a card-shaped data carrier so that one or more graphic elements of the card body are visually highlighted well.

Diese Aufgabe wird durch einen kartenförmigen Datenträger mit der Merkmalskombination eines der unabhängigen Ansprüche gelöst.This object is achieved by a card-shaped data carrier with the feature combination of one of the independent claims.

Der erfindungsgemäße kartenförmige Datenträger weist einen Kartenkörper auf, auf dem ein graphisches Element dargestellt ist. Der Kartenkörper weist ein Kunststoffmaterial zur Umwandlung von eingestrahltem Licht in Sekundärlicht und zur Weiterleitung des Sekundärlichts innerhalb des Kunststoffmaterials zum graphischen Element oder zu einem Teilbereich des graphischen Elements auf. Eine Besonderheit des kartenförmigen Datenträgers besteht darin, dass ein durch das Kunststoffmaterial gebildeter Formkörper zur Darstellung des graphischen Elements wenigstens teilweise in wenigstens einer Ausnehmung des Kartenkörpers angeordnet ist und/oder ein lateral ausgedehntes Gebiet aufweist, innerhalb dessen der Formkörper andere optische Eigenschaften als außerhalb des Gebiets besitzt.The card-shaped data carrier according to the invention has a card body on which a graphic element is shown. The card body comprises a plastic material for converting incident light into secondary light and for relaying the secondary light within the plastic material to the graphic element or to a portion of the graphic element. A special feature of the card-shaped data carrier is that a molded body formed by the plastic material for displaying the graphic element is at least partially disposed in at least one recess of the card body and / or has a laterally extended area, within which the shaped body has different optical properties than outside the area has.

Dies hat den Vorteil, dass mit einem vertretbaren Aufwand eine deutliche visuelle Hervorhebung eines graphischen Elements auf einem Kartenkörper möglich ist. Der erfindungsgemäße kartenförmige Datenträger ist langlebig und weist ein hochwertiges und markantes äußeres Erscheinungsbild auf.This has the advantage that with a reasonable effort a clear visual highlighting of a graphical element on a card body is possible. The card-shaped data carrier according to the invention is durable and has a high quality and distinctive external appearance.

In einem bevorzugten Ausführungsbeispiel des kartenförmigen Datenträgers ist der Formkörper wenigstens bereichsweise klar (klar durchsichtig oder klarsichtig), ausgebildet. Dadurch wird erreicht, dass die Umrisse des Formkörpers in den klar ausgebildeten Bereichen eine erhöhte Helligkeit aufweisen.In a preferred exemplary embodiment of the card-shaped data carrier, the shaped body is at least partially clear (clearly transparent or clear). This ensures that the contours of the molded body in the clearly formed areas have an increased brightness.

Der Formkörper kann innerhalb der Ausnehmung klar oder milchig ausgebildet sein. Auf diese Weise ist es möglich, dass entweder die Umrisse der Ausnehmung durch eine erhöhte Helligkeit in Erscheinung treten oder die Ausnehmung über ihre gesamte Fläche ungefähr die gleiche Helligkeit aufweist.The shaped body can be made clear or milky within the recess. In this way, it is possible that either the outlines of the recess by an increased brightness in appearance or the recess has approximately the same brightness over its entire surface.

Besonders vorteilhaft ist es, wenn der Formkörper eine größere laterale Erstreckung als die Ausnehmung aufweist. Dadurch kommt es zu einer Konzentration des Lichts im Bereich der Ausnehmung, so dass eine hohe Helligkeit erreicht wird.It is particularly advantageous if the shaped body has a greater lateral extent than the recess. This results in a concentration of light in the region of the recess, so that a high brightness is achieved.

Der Kartenkörper ist in der lateralen Umgebung der Ausnehmung vorzugsweise opak ausgebildet. Dies hat den Vorteil, dass ein hoher Kontrast erzielt werden kann und außerhalb der Ausnehmung keine unerwünschten Effekte durch Streulicht auftreten. Insbesondere kann das lateral an die Ausnehmung angrenzende Kartenmaterial opak sein. Ebenso ist es auch möglich, dass der Kartenkörper wenigstens in einer lateralen Umgebung der Ausnehmung opak bedruckt ist.The card body is preferably opaque in the lateral environment of the recess. This has the advantage that a high contrast can be achieved and outside of the recess no undesired effects occur due to stray light. In particular, the card material laterally adjacent to the recess may be opaque. Likewise, it is also possible that the card body is printed opaque at least in a lateral environment of the recess.

Die andersartigen optischen Eigenschaften innerhalb eines Gebiets des Formkörpers lassen sich auf unterschiedliche Weise realisieren. Beispielsweise kann der Formkörper innerhalb dieses Gebiets milchig ausgebildet sein. In diesem Fall ist die Helligkeit innerhalb des gesamten Gebiets etwas höher als in dessen Umgebung. Ebenso ist es auch möglich, dass der Formkörper in-. nerhalb des Gebiets eine dreidimensionale Oberflächenstruktur aufweist. Dies führt ebenfalls zu einer erhöhten Helligkeit innerhalb des Gebiets. Die dreidimensionale Oberflächenstruktur kann durch eine Vielzahl von Erhöhungen und/ oder Vertiefungen gebildet werden, die über die gesamte Fläche des Gebiets verteilt sind.The different optical properties within a region of the molding can be realized in different ways. For example, the shaped body may be milky within this area. In this case, the brightness is slightly higher throughout the area than in its surroundings. Likewise, it is also possible that the shaped body in. has a three-dimensional surface structure within the area. This also leads to increased brightness within the area. The three-dimensional surface structure may be formed by a plurality of ridges and / or depressions distributed over the entire area of the area.

Das Sekundärlicht wird vorzugsweise parallel zu einer Hauptfläche des Formkörpers weitergeleitet. Insbesondere zum Schutz gegen Verschmutzung und Abnutzung kann der Kartenkörper auf wenigstens einer Hauptfläche eine transparente Deckschicht aufweisen. Der Kartenkörper ist vorzugsweise durch Lamination hergestellt. Mit der Laminationstechnik lässt sich das Kunststoffmaterial gut verarbeiten und ein qualitativ hochwertiger Kartenkörper herstellen. Der Formkörper ist bevorzugt als ein Stanzteil ausgebildet.The secondary light is preferably forwarded parallel to a main surface of the shaped body. In particular, for protection against soiling and wear, the card body may have a transparent cover layer on at least one main surface. The card body is preferably made by lamination. With the Laminationstechnik can be process the plastic material well and produce a high-quality card body. The shaped body is preferably formed as a stamped part.

Der Kartenkörper kann einen Magnetstreifen und/ oder einen integrierten Schaltkreis aufweisen.The card body may comprise a magnetic strip and / or an integrated circuit.

Die Erfindung wird nachstehend anhand der in der Zeichnung dargestellten Ausführungsbeispiele erläutert.The invention will be explained below with reference to the embodiments illustrated in the drawings.

Fig.1 zeigt ein erstes Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Karte 1 in einer schematischen Aufsicht. Eine zugehörige schematische Schnittdarstellung ist in Fig. 2 dargestellt. Die Karte 1 ist vorzugsweise als eine Chipkarte ausgebildet, die einen Kartenkörper 2 aufweist, in den ein Chipmodul 3 eingebettet ist. Das Chipmodul 3 weist einen integrierten Schaltkreis 4 und ein Kontaktfeld 5 auf, das mit dem integrierten Schaltkreis 4 verbunden ist. Zur Durchführung einer Datenübertragung zwischen dem integrierten Schaltkreis 4 und einem nicht figürlich dargestellten externen Gerät wird das Kontaktfeld 5 des Chipmoduls 3 vom externen Gerät berührend kontaktiert. Alternativ zur Darstellung der Fig.1 und 2 kann das Chipmodul 3 auch für eine kontaktlose Datenübertragung ausgebildet sein und dann insbesondere im Inneren des Kartenkörpers 2 angeordnet sein. Ebenso kann die Karte 1 auch mit einem nicht figürlich dargestellten Magnetstreifen zur Speicherung von Daten ausgestattet sein. Dies alles gilt jeweils auch für die weiteren Ausführungsbeispiele der Karte 1. Bei diesen Ausführungsbeispielen wurde zum Teil von einer figürlichen Darstellung des Chipmoduls 3 abgesehen. Fig.1 shows a first embodiment of an inventively designed card 1 in a schematic plan view. An associated schematic sectional view is in Fig. 2 shown. The card 1 is preferably designed as a chip card, which has a card body 2, in which a chip module 3 is embedded. The chip module 3 has an integrated circuit 4 and a contact pad 5, which is connected to the integrated circuit 4. To carry out a data transfer between the integrated circuit 4 and an external figuratively not shown Device, the contact pad 5 of the chip module 3 is contacted by the external device touching. Alternatively to the representation of Fig.1 and 2 For example, the chip module 3 may also be designed for contactless data transmission and then be arranged in particular in the interior of the card body 2. Likewise, the card 1 may also be equipped with a non-figured magnetic strip for storing data. This also applies in each case to the further exemplary embodiments of the card 1. In these exemplary embodiments, a figurative representation of the chip module 3 was dispensed with in part.

Der Kartenkörper 2 weist ein graphisches Element 6, beispielsweise in Form einer Beschriftung, einer Flagge, eines Logos, eines Emblems oder eines sonstigen Symbols auf. Das graphische Element 6 tritt visuell durch gegenüber der Umgebung aufgehellte Bereiche in Erscheinung. Dies wird durch einen Aufbau des Kartenkörpers 2 erreicht, bei dem mehrere Kunststofffolien mit unterschiedlichen optischen Eigenschaften durch Lamination miteinander verbunden sind.The card body 2 has a graphic element 6, for example in the form of a label, a flag, a logo, an emblem or another symbol. The graphic element 6 appears visually through areas brightened up to the environment. This is achieved by a construction of the card body 2, in which a plurality of plastic films with different optical properties are interconnected by lamination.

Im einzelnen weist der Kartenkörper 2 beim ersten Ausführungsbeispiel eine Kernfolie 7 auf, deren erste Hauptfläche durch eine erste Deckfolie 8 und deren zweite Hauptfläche durch eine zweite Deckfolie 9 abgedeckt ist. Die Kernfolie 7 ist auf beiden Seiten vollflächig mit einem Aufdruck 10 versehen, der im Bereich des sichtbaren Lichts opak ist. Der Aufdruck 10 kann auch auf die Innenseiten, d. h. die an die Kernfolie 7 angrenzenden Hauptflächen, der Deckfolien 8 und 9 aufgebracht sein. Die Deckfolien 8 und 9 sind jeweils im Bereich des sichtbaren Lichts transparent ausgebildet.In detail, the card body 2 in the first exemplary embodiment has a core film 7 whose first main surface is covered by a first cover film 8 and whose second main surface is covered by a second cover film 9. The core film 7 is provided on both sides of the entire surface with a print 10, which is opaque in the visible light range. The imprint 10 may also be applied to the insides, i. H. the main surfaces adjacent to the core film 7, the cover films 8 and 9 are applied. The cover films 8 and 9 are each transparent in the visible light region.

In der Kernfolie 7 ist eine fensterartige Ausnehmung 11 ausgespart, deren Form durch das graphische Element 6 bestimmt ist. Innerhalb der Ausnehmung 11 ist die Kernfolie 7 durch eine Lichtsammelfolie 12 ersetzt, welche die äußere Form des graphischen Elements 6 aufweist und beispielsweise durch einen Stanzprozess hergestellt ist. Die Lichtsammelfolie 12 ist transparent und insbesondere klar ausgebildet, d. h. durch die Lichtsammelfolie 12 hindurch sind die Umrisse eines Gegenstands deutlich erkennbar. Im Bereich der Ausnehmung 11 ist kein Aufdruck 10 vorgesehen, d. h. die Lichtsammelfolie 12 wird durch den Aufdruck 10 nicht verdeckt. Allerdings erstrecken sich die Deckfolien 8 und 9 auch jeweils über die Ausnehmung 11, so dass die Lichtsammelfolie 12 beidseitig von den Deckfolien 8 bzw. 9 abgedeckt wird. Wie anhand von Fig. 3 noch näher erläutert wird, erscheint der Bereich der Lichtsammelfolie 12 etwas heller als die Umgebung und weist entlang ihrer Kontur, d. h. der Grenzfläche zur lateral benachbarten Kernfolie 7, eine deutlich erhöhte Helligkeit auf. Das graphische Element 6 zeichnet sich somit durch eine sehr hell erscheinende Kontur aus.In the core film 7, a window-like recess 11 is recessed, the shape of which is determined by the graphic element 6. Inside the recess 11, the core sheet 7 is replaced by a light-collecting sheet 12 having the outer shape of the graphic element 6 and made by, for example, a punching process. The light-collecting film 12 is transparent and in particular has a clear design, that is to say that the contours of an object can be clearly recognized through the light-collecting film 12. In the region of the recess 11 no imprint 10 is provided, that is, the light-collecting sheet 12 is not obscured by the imprint 10. However, the cover films 8 and 9 also extend in each case over the recess 11, so that the light-collecting film 12 is covered on both sides by the cover films 8 and 9, respectively. As based on Fig. 3 will be explained in more detail, the area of the light-collecting film 12 appears slightly lighter than the environment and has along its contour, ie the interface to the laterally adjacent core film 7, a significantly increased brightness. The graphical element 6 is thus characterized by a very bright appearing contour.

Bei einer Abwandlung des ersten Ausführungsbeispiels der Karte 1 entfällt die erste Deckfolie 8 und/oder die zweite Deckfolie 9.In a modification of the first exemplary embodiment of the card 1, the first cover film 8 and / or the second cover film 9 is omitted.

Fig. 3 zeigt die Lichtsammelfolie 12 in einer schematischen Schnittdarstellung. Die Lichtsammelfolie 12 besteht aus einem Kunststoff, beispielsweise aus Polycarbonat oder PVC, in den ein fluoreszierender Farbstoff eingelagert ist. In Fig. 3 ist beispielhaft ein Farbstoffpartikel 13 in starker Vergrößerung dargestellt. Bei Bestrahlung mit Licht wird der Farbstoffpartikel 13 zur Fluoreszenz angeregt und strahlt in alle Richtungen Fluoreszenzlicht aus, das eine größere Wellenlänge als das einfallende Licht aufweist. Die einfallenden Lichtstrahlen sind in Fig. 3 mit der Bezugsziffer 14, die Strahlen des Fluoreszenzlichts mit den Bezugsziffern 15 und 16 bezeichnet. Fig. 3 shows the light-collecting sheet 12 in a schematic sectional view. The light-collecting film 12 consists of a plastic, for example of polycarbonate or PVC, in which a fluorescent dye is incorporated. In Fig. 3 For example, a dye particle 13 is shown in high magnification. When irradiated with light, the dye particle 13 is excited to fluoresce and radiates in all directions fluorescent light having a larger wavelength than the incident light. The incident light rays are in Fig. 3 designated by the reference numeral 14, the rays of the fluorescent light by the reference numerals 15 and 16.

Die Fluoreszenzstrahlen 15 treffen unter relativ groben Winkeln auf die Hauptflächen der Lichtsammelfolie 12, die jeweils eine Grenzfläche zwischen der Lichtsammelfolie 12 und der Luft darstellen, welche die Lichtsammelfolie 12 umgibt. Da die Lichtsammelfolie 12 eine größere Brechzahl als die Luft aufweist, kommt es bei Winkeln oberhalb des Grenzwinkels der Totalreflexion zu einer Reflexion an der Grenzfläche. Anzumerken ist, dass der Winkel jeweils zum Lot der Oberfläche gemessen wird. Dies bedeutet, dass die Fluoreszenzstrahlen 15 die Lichtsammelfolie 12 nicht verlassen, sondern abwechselnd an den gegenüberliegenden Hauptflächen reflektiert werden, bis sie eine der Stirnflächen der Lichtsammelfolie 12 erreichen, welche die beiden Hauptflächen miteinander verbinden. Da die Fluoreszenzstrahlen 15 unter einem relativ kleinen Winkel auf die Stirnfläche treffen, treten Sie durch die Stirnfläche hindurch aus der Lichtsammelfolie 12 aus. Beim Durchtritt durch die Stirnfläche werden die Fluoreszenzstrahlen 15 entsprechend dem Brechzahlverhältnis zwischen der Lichtsammelfolie 12 und der umgebenden Luft gebrochen.The fluorescent rays 15 strike the major surfaces of the light-collecting sheet 12 at relatively coarse angles, each of which constitutes an interface between the light-collecting sheet 12 and the air surrounding the light-collecting sheet 12. Since the light-collecting sheet 12 has a greater refractive index than the air, at angles above the critical angle of total reflection, reflection occurs at the boundary surface. It should be noted that the angle is measured in each case to the perpendicular of the surface. That is, the fluorescent rays 15 do not leave the light-collecting sheet 12, but are alternately reflected on the opposite major surfaces until they reach one of the end faces of the light-gathering sheet 12 connecting the two main surfaces. Since the fluorescent rays 15 impinge on the end surface at a relatively small angle, they exit the light-collecting film 12 through the end surface. When passing through the end face, the fluorescent rays 15 are refracted according to the refractive index ratio between the light-collecting sheet 12 and the surrounding air.

Die Fluoreszenzstrahlen 16, die unter einem Winkel unterhalb des Grenzwinkels der Totalreflexion auf eine der Hauptflächen der Lichtsammelfolie 12 treffen, treten durch die Hauptfläche hindurch und werden dabei gebrochen. Dies bedeutet, dass die auf die Hautflächen der Lichtsammelfolie 12 auftreffenden Lichtstrahlen 14 Fluoreszenzstrahlen 15 und 16 erzeugen, welche die Lichtsammelfolie 12 teils über deren Stirnflächen und teils über deren Hauptflächen verlassen. Da die Stirnflächen einen erheblich kleineren Flächeninhalt als die Hauptflächen aufweisen, konzentriert sich das Licht im Bereich der Stirnflächen und führt dort zu einer erhöhten Helligkeit.The fluorescent rays 16, which impinge on one of the major surfaces of the light-collecting sheet 12 at an angle below the limit angle of total reflection, pass through the main surface and are thereby refracted. This means that the light beams 14 impinging on the skin surfaces of the light-collecting film 12 produce fluorescence beams 15 and 16 which leave the light-collecting film 12 partly over their end faces and partly over their main surfaces. Since the end faces have a significantly smaller surface area than the main surfaces, the light concentrates in the region of the end faces and leads there to an increased brightness.

Fig. 4 zeigt eine Ausgestaltung der Karte 1 in einer schematischen Aufsicht. Eine zugehörige schematische Schnittdarstellung ist in Fig. 5 dargestellt. Im Unterschied zum ersten Ausführungsbeispiel der Karte 1 weist diese nicht erfindungsgemäße Ausgestaltung kein graphisches Element 6 mit besonders hellen Konturen auf. Stattdessen ist die gesamte Fläche des graphischen Elements 6 gleichmäßig ausgeleuchtet. Fig. 4 shows an embodiment of the card 1 in a schematic plan view. An associated schematic sectional view is in Fig. 5 shown. In contrast to the first embodiment of the card 1, this embodiment not according to the invention has no graphic element 6 with particularly bright contours. Instead, the entire area of the graphic element 6 is uniformly illuminated.

Dies wird dadurch erreicht, dass die Lichtsammelfolie 12 beim zweiten Ausführungsbeispiel nicht auf den Bereich des graphischen Elements 6 begrenzt ist, sondern lateral darüber hinausgeht und sich vorzugsweise über den gesamten Kartenkörper 2 erstreckt. Die Hauptflächen der Lichtsammelfolie 12 sind mit den transparenten Deckfolien 8 und 9 abgedeckt. Die Lichtsammelfolie 12 ist klar ausgebildet und weist im Bereich des graphischen Elements 6 eine dreidimensionale Oberflächenstruktur 17 auf. Die Oberflächenstruktur 17 ist in dem vergrößerten Ausschnitt der Fig. 5 dargestellt und weist eine Vielzahl von lateral aufeinander folgenden Erhöhungen und Vertiefungen auf, die beispielsweise wellenförmig ausgebildet sein können. Durch die Oberflächenstruktur 17 wird der Anteil der an der Grenzfläche der Lichtsammelfolie 12 reflektierten Fluoreszenzstrahlen 15 reduziert und der Anteil der die Grenzfläche passierenden Fluoreszenzstrahlen 16 erhöht. Dies hat zur Folge, dass der gesamte Bereich der Oberflächenstruktur 17 heller erscheint als die benachbarten Bereiche der Lichtsammelfolie 12 mit glatter Oberfläche. Die Kontur des graphischen Elements 6 weist gegenüber dessen Innenbereich keine oder nur eine geringfügig erhöhte Helligkeit auf.This is achieved in that the light-collecting sheet 12 in the second embodiment is not limited to the area of the graphic element 6, but laterally beyond and preferably extends over the entire card body 2. The main surfaces of the light-collecting sheet 12 are covered with the transparent cover sheets 8 and 9. The light-collecting film 12 is clearly formed and has a three-dimensional surface structure 17 in the region of the graphic element 6. The surface structure 17 is in the enlarged section of Fig. 5 shown and has a plurality of laterally successive elevations and depressions, which may be formed, for example, wave-shaped. The surface structure 17 reduces the proportion of the fluorescence beams 15 reflected at the interface of the light-collecting film 12 and increases the proportion of the fluorescence beams 16 passing through the interface. As a result, the entire area of the surface structure 17 appears brighter than the adjacent areas of the light-collecting surface 12 having a smooth surface. The contour of the graphic element 6 has no or only slightly increased brightness relative to its inner region.

Bei einer Abwandlung dieser Ausgestaltung der Karte 1 entfällt die erste Deckfolie 8 und/oder die zweite Deckfolie 9.In a modification of this embodiment of the card 1 eliminates the first cover sheet 8 and / or the second cover sheet. 9

Fig. 6 zeigt ein drittes Ausführungsbeispiel der Karte 1 in einer schematischen Schnittdarstellung. Die zugehörige Aufsicht entspricht der Fig. 4. Beim dritten Ausführungsbeispiel ist die Lichtsammelfolie 12 innerhalb des graphischen Elements 6 milchig ausgebildet und außerhalb des graphischen Elements 6 klar. Dies kann mit einer lateral durchgehenden Lichtsammelfolie 12 realisiert werden, die unterschiedlich behandelte Bereiche aufweist. Ebenso können auch mehrere unterschiedliche Lichtsammelfolien 12 lateral nebeneinander angeordnet werden. In beiden Fällen sind die Hauptflächen der Lichtsammelfolien 12 durch die Deckfolien 8 und 9 abgedeckt. Fig. 6 shows a third embodiment of the card 1 in a schematic sectional view. The corresponding supervision corresponds to the Fig. 4 , In the third embodiment, the light-collecting sheet 12 is within the graphic Elements 6 milky and outside the graphic element 6 clear. This can be realized with a laterally continuous light-collecting foil 12 having differently treated areas. Likewise, a plurality of different light-collecting foils 12 can be arranged laterally side by side. In both cases, the major surfaces of the light-collecting sheets 12 are covered by the cover sheets 8 and 9.

Beim dritten Ausführungsbeispiel der Karte 1 führt die im Bereich des graphischen Elements 6 milchige Ausbildung der Lichtsammelfolie 12 dazu, dass das graphische Element 6 vollflächig heller erscheint als dessen Umgebung. Im Gegensatz zum zweiten Ausführungsbeispiel der Karte 1 sind die Hauptflächen der Lichtsammelfolie 12 auch im Bereich des graphischen Elements 6 glatt ausgebildet.In the third exemplary embodiment of the card 1, the milky formation of the light-collecting foil 12 in the region of the graphic element 6 causes the graphic element 6 to appear brighter over its entire surface than its surroundings. In contrast to the second embodiment of the card 1, the main surfaces of the light-collecting sheet 12 are formed smooth even in the region of the graphic element 6.

Weiterhin wird ein deutlicher Effekt durch den Einsatz in unterschiedlichen Farben fluoreszierender Bereiche erreicht. So kann der milchige Bereich des graphischen Elements 6 langwellig, beispielsweise orange, und der klare Bereich der Lichtsammelfolie 12 kurzwellig, also beispielsweise grün fluoreszieren.Furthermore, a significant effect is achieved by use in different colors of fluorescent areas. Thus, the milky area of the graphic element 6 long-wave, for example, orange, and the clear area of the light-collecting sheet 12 short-wave, so for example green fluoresce.

Fig. 7 zeigt ein viertes Ausführungsbeispiel der Karte 1 in einer schematischen Aufsicht. Eine zugehörige schematische Schnittdarstellung ist in Fig. 8 dargestellt. Der Kartenkörper 2 weist eine opake Kernfolie 7 mit mehreren Ausnehmungen 11 für je ein graphisches Element 6 auf. Weiterhin weist der Kartenkörper 2 eine Lichtsammelfolie 12 auf, die mit ihrer Hauptfläche ans die Hauptfläche der Kernfolie 7 angrenzt und somit neben der Kernfolie 7 eine weitere Schicht des Kartenkörpers 2 darstellt. Dabei erstreckt sich die Lichtsammelfolie 12 in die Ausnehmungen 11 der Kernfolie 7 und füllt diese jeweils vollständig aus. Die Hauptflächen des Kartenkörpers 2 werden durch je eine transparente Deckfolie 8 bzw. 9 gebildet, d. h. sowohl die Kernfolie 7 als auch die Lichtsammelfolie 12 sind durch eine Deckfolie 8 bzw. 9 abgedeckt. Fig. 7 shows a fourth embodiment of the card 1 in a schematic plan view. An associated schematic sectional view is in Fig. 8 shown. The card body 2 has an opaque core film 7 with a plurality of recesses 11 for each graphical element 6. Furthermore, the card body 2 has a light-collecting foil 12 which adjoins the main surface of the core foil 7 with its main surface and thus represents a further layer of the card body 2 in addition to the core foil 7. In this case, the light-collecting film 12 extends into the recesses 11 of the core film 7 and fills these completely. The main surfaces of the card body 2 are through each one transparent cover sheet 8 or 9 formed, that is, both the core sheet 7 and the light-collecting sheet 12 are covered by a cover sheet 8 and 9 respectively.

Die Lichtsammelfolie 12 kann durchgehend, d. h. sowohl innerhalb der durch die Lichtsammelfolie 12 ausgebildeten Schicht als auch innerhalb der Ausnehmungen 11 der Kernfolie 7, klar ausgebildet sein. In diesem Fall erscheinen die Konturen der graphischen Elemente 6 sehr hell, da über eine gesamte Hauptfläche des Kartenkörpers 2 Licht in die Lichtsammelfolie 12 eingestrahlt wird und das Fluoreszenzlicht lediglich über die Stirnflächen der Lichtsammelfolie 12 und über die Ränder der Ausnehmungen 11 in der Kernfolie 7 entweichen kann. Die Helligkeit ist umso größer, je kleiner die Fläche der Ausnehmungen 11 in der Kernfolie 7 ist.The light-collecting sheet 12 can be continuous, d. H. both within the layer formed by the light-collecting film 12 and within the recesses 11 of the core film 7, be clear. In this case, the contours of the graphic elements 6 appear very bright, since light is irradiated into the light-collecting sheet 12 over an entire main surface of the card body 2 and the fluorescent light only escapes over the end faces of the light-collecting sheet 12 and over the edges of the recesses 11 in the core sheet 7 can. The brightness is greater, the smaller the area of the recesses 11 in the core film 7 is.

Wenn eine vollflächige Ausleuchtung der Ausnehmungen 11 in der Kernfolie 7 gewünscht wird, kann das vierte Ausführungsbeispiel so abgewandelt werden, dass die Lichtsammelfolie 12 im Bereich einer oder mehrerer Ausnehmungen 11 in der Kernfolie 7 die beim zweiten Ausführungsbeispiel beschriebene dreidimensionale Oberflächenstruktur 17 aufweist. Ebenso ist es auch möglich, eine oder mehrere der Ausnehmungen 11 in der Kernfolie 7 mit einer milchigen Lichtsammelfolie 12 zu füllen.If a full-surface illumination of the recesses 11 in the core film 7 is desired, the fourth embodiment can be modified so that the light-collecting film 12 in the region of one or more recesses 11 in the core film 7 has the three-dimensional surface structure 17 described in the second embodiment. Likewise, it is also possible to fill one or more of the recesses 11 in the core film 7 with a milky light-collecting film 12.

Fig. 9 zeigt ein fünftes Ausführungsbeispiel der Karte 1 in einer schematischen Schnittdarstellung. Die zugehörige Aufsicht entspricht der Fig.1. Beim fünften Ausführungsbeispiel ist eine Leuchtdiode 18 in der Lichtsammelfolie 12 angeordnet. Die Lichtsammelfolie 12 ist, ähnlich wie beim ersten Ausführungsbeispiel, in einer Ausnehmung 11 in der Kernfolie 7 angeordnet. Die Kernfolie 7 ist beidseits mit einem opaken Aufdruck 10 versehen, der sich lateral auch zum Teil über die Lichtsammelfolie 12 erstreckt. Dadurch wird insbesondere verhindert, dass die Leuchtdiode 18 von außerhalb des Kartenkörpers 2 sichtbar ist. Die Hauptflächen des Kartenkörpers 2 werden durch je eine Deckfolie 8 bzw. 9 gebildet, die sowohl die Aufdrucke 10 als auch die Lichtsammelfolie 12 abdecken. Fig. 9 shows a fifth embodiment of the card 1 in a schematic sectional view. The corresponding supervision corresponds to the Fig.1 , In the fifth embodiment, a light emitting diode 18 is disposed in the light collecting sheet 12. The light-collecting film 12 is, similar to the first embodiment, arranged in a recess 11 in the core film 7. The core film 7 is provided on both sides with an opaque imprint 10, which extends laterally also partially over the light-collecting sheet 12. This will in particular prevents the light-emitting diode 18 is visible from outside the card body 2. The main surfaces of the card body 2 are each formed by a cover sheet 8 or 9, which cover both the imprints 10 and the light-collecting sheet 12.

Durch die Leuchtdiode 18 ist eine ausreichende Helligkeit des graphischen Elements 6 unabhängig von den jeweils herrschenden Lichtverhältnissen gewährleistet. Allerdings ist hierfür eine Stromversorgung der Leuchtdiode 18 erforderlich. Diese kann beispielsweise über ein Gerät erfolgen, welches die Karte 1 zur Durchführung einer Datenübertragung berührend kontaktiert. Dabei sollte die Kontaktierung so erfolgen, dass das graphische Element 6 sichtbar bleibt. Andere Möglichkeiten der Stromversorgung für die Leuchtdiode 18 werden im folgenden beschrieben.By the light emitting diode 18, a sufficient brightness of the graphic element 6 is ensured regardless of the prevailing light conditions. However, a power supply of the light emitting diode 18 is required for this purpose. This can be done for example via a device which contacts the card 1 to carry out a data transfer. The contacting should be such that the graphic element 6 remains visible. Other ways of powering the light emitting diode 18 will be described below.

Fig. 10 zeigt ein sechstes Ausführungsbeispiel der Karte 1 in einer schematischen Schnittdarstellung. Die zugehörige Aufsicht entspricht der Fig.1 ohne das Chipmodul 3. Beim sechsten Ausführungsbeispiel sind innerhalb der Kernfolie 7 eine Batterie 19 als Stromversorgung für die Leuchtdiode 18 und ein Drucktaster 20 zum Ein- und Ausschalten der Leuchtdiode 18 angeordnet. Ansonsten entspricht der Aufbau des Kartenkörpers 2 dem fünften Ausführungsbeispiel. Die eingebaute Batterie 19 ermöglicht es, die Leuchtdiode 18 unabhängig von einem externen Gerät in Betrieb zu nehmen. Mögliche Beschaltungen der Leuchtdiode 18 sind in Fig. 11 dargestellt. Fig. 10 shows a sixth embodiment of the card 1 in a schematic sectional view. The corresponding supervision corresponds to the Fig.1 without the chip module 3. In the sixth embodiment, a battery 19 as a power supply for the light emitting diode 18 and a push button 20 for switching on and off of the light emitting diode 18 are disposed within the core film 7. Otherwise, the structure of the card body 2 corresponds to the fifth embodiment. The built-in battery 19 makes it possible to operate the light-emitting diode 18 independently of an external device. Possible connections of the light emitting diode 18 are in Fig. 11 shown.

Fig. 11 zeigt je einen Schaltplan für zwei unterschiedliche Beschaltungen der beim sechsten Ausführungsbeispiel der Karte 1 vorgesehenen Leuchtdiode 18. Bei dem links dargestellten Schaltplan ist die Leuchtdiode 18 über den Drucktaster 20 und einen Widerstand 21, die der Leuchtdiode 18 in Serie geschaltet sind, an die Batterie 19 angeschlossen. Bei dem rechts dargestellten Schaltplan entfällt der Widerstand 21. Fig. 11 each shows a circuit diagram for two different circuits of the sixth embodiment of the card 1 provided light emitting diode 18. In the circuit diagram shown on the left is the light emitting diode 18 via the push button 20 and a resistor 21, the light emitting diode 18 connected in series are connected to the battery 19. In the circuit diagram shown on the right eliminates the resistor 21st

Fig. 12 zeigt ein siebtes Ausführungsbeispiel der Karte 1 in einer schematischen Schnittdarstellung. Die zugehörige Aufsicht entspricht der Fig. 1 ohne das Chipmodul 3. Der Aufbau des Kartenkörpers 2 entspricht in weiten Zügen dem sechsten Ausführungsbeispiel. Allerdings weist der Kartenkörper 2 beim siebten Ausführungsbeispiel weder eine Batterie 19 noch einen Drucktaster 20 auf. Stattdessen ist in der Kernfolie 7 eine Antennenspule 22 angeordnet, mit deren Hilfe die Leuchtdiode 18 mit Energie versorgt wird. Hierzu ist es erforderlich, dass sich die Karte 1 in der Nähe eines Sendegeräts befindet, das ein elektromagnetisches Feld erzeugt, welches auf die Antennenspule 22 der Karte 1 einwirkt. Die diesbezügliche Beschaltung der Leuchtdiode 18 ist in Fig. 13 dargestellt. Bei dem Sendegerät kann es sich um ein herkömmliches Gerät für eine kontaktlose Kommunikation mit der Karte 1 handeln. Fig. 12 shows a seventh embodiment of the card 1 in a schematic sectional view. The corresponding supervision corresponds to the Fig. 1 without the chip module 3. The construction of the card body 2 broadly corresponds to the sixth embodiment. However, in the seventh embodiment, the card body 2 has neither a battery 19 nor a push button 20. Instead, an antenna coil 22 is arranged in the core film 7, by means of which the light-emitting diode 18 is supplied with energy. For this purpose, it is necessary that the card 1 is located in the vicinity of a transmitting device which generates an electromagnetic field which acts on the antenna coil 22 of the card 1. The relevant wiring of the light emitting diode 18 is in Fig. 13 shown. The transmitter may be a conventional contactless communication device with the card 1.

Fig. 13 zeigt je einen Schaltplan für zwei unterschiedliche Beschaltungen der Leuchtdiode 18 beim siebten Ausführungsbeispiel der Karte 1. Beim links dargestellten Schaltplan ist die Leuchtdiode 18 über einen in Serie geschalteten Widerstand 21 an die Antennespule 22 angeschlossen. Bei dem rechts dargestellten Schaltplan ist die Leuchtdiode 18 direkt an die Antennenspule 22 angeschlossen. Fig. 13 each shows a circuit diagram for two different circuits of the light emitting diode 18 in the seventh embodiment of the card 1. In the circuit diagram shown on the left, the light emitting diode 18 is connected via a series resistor 21 to the antenna coil 22. In the circuit diagram shown on the right, the light emitting diode 18 is connected directly to the antenna coil 22.

Alternativ kann die Leuchtdiode auch mit einem Chip, der zum Zwecke einer kontaktlosen Kommunikation an eine Antenne angebunden ist, verbunden sein.Alternatively, the light-emitting diode may also be connected to a chip, which is connected to an antenna for the purpose of contactless communication.

Die Ausführungsbeispiele, bei denen die Karte 1 eine Leuchtdiode 18 aufweist, können mit den zuvor ohne Leuchtdiode 18 beschriebenen Aufbauten für den Kartenkörper 2 kombiniert werden. So kann bei einer Karte 1 mit Leuchtdiode 18 beispielsweise eine Lichtsammelfolie 12 mit einer dreidimensionalen Oberflächenstruktur 17 oder eine milchige Lichtsammelfolie 12 eingesetzt werden.The exemplary embodiments in which the card 1 has a light-emitting diode 18 can be combined with the structures for the card body 2 previously described without light-emitting diode 18. For example, in the case of a card 1 with light-emitting diode 18, a light-collecting foil 12 having a three-dimensional surface structure 17 or a milky light-collecting foil 12 can be used.

Alle Ausführungsbeispiele, bei denen dies nicht ohnehin der Fall ist, können so abgewandelt werden, dass die graphischen Elemente 6 in der Nähe des Rands des Kartenkörpers 2 angeordnet sind. Dadurch wird erreicht, dass die graphischen Elemente 6 auch dann noch sichtbar sind, wenn die Karte 1 beispielsweise in einer Geldbörse aufbewahrt wird. Die dafür vorgesehenen Aufbewahrungsfächer decken den Kartenkörper 2 in der Regel nicht vollständig ab.All embodiments in which this is not the case anyway, can be modified so that the graphic elements 6 are arranged in the vicinity of the edge of the card body 2. This ensures that the graphic elements 6 are still visible even when the card 1 is stored for example in a wallet. The storage compartments provided for this purpose generally do not cover the card body 2 completely.

Der Kartenkörper 2 wird bei den vorstehend beschriebenen Ausführungsbeispielen der Karte 1 jeweils bevorzugt durch Lamination mehrerer Folien hergestellt. Dabei wird die Lichtsammelfolie 12 in den Fällen, in denen ihre Kontur durch das graphische Element 6 bestimmt wird, bevorzugt durch Stanzen in die gewünschte Form gebracht.In the embodiments of the card 1 described above, the card body 2 is preferably produced by laminating a plurality of films. In this case, the light-collecting film 12 is preferably brought into the desired shape by punching in the cases in which its contour is determined by the graphic element 6.

Ebenso ist es auch möglich, den Kartenkörper 2 auf andere Weise, beispielsweise im Spritzgussverfahren, herzustellen.Likewise, it is also possible to produce the card body 2 in other ways, for example by injection molding.
