Abstract
Kontaktbehaftete Chipkarte, die metallische Kontakte (2A) zur Kommunikation mit externen Geräten aufweist, dadurch gekennzeichnet, daß sich auf mindestens einem der Kontakte (2A) vollflächig oder teilweise eine ebene Interferenzbeschichtung (3) mit einer Dicke kleiner als 0,1 μm befindet, wobei die Oberfläche der Kontakte (2A) in diesen Bereichen bei der Betrachtung unter weißem Licht in Abhängigkeit vom Betrachtungswinkel und/oder der Ausrichtung der Karte zum einfallenden Licht in verschiedenen Regenbogenfarben erscheint. Contact-based Chip card having metallic contacts (2A) for communicating with external devices, characterized in that on at least one of the contacts (2A) over the entire surface or partially a plane Interference coating (3) having a thickness smaller than 0.1 μm, the surface the contacts (2A) in these areas under consideration white Light in dependence from the viewing angle and / or orientation of the card to the incident Light in different rainbow colors appears.
Description
Die Erfindung bezieht sich auf eine kontaktbehaftete Chipkarte. Derartige Chipkarten enthalten ein Chipmodul, d.h. ein Trägerelement für den Chip/IC-Baustein, mit elektrisch leitfähigen Kontakten. Diese Kontakte sind mit entsprechenden Anschlußpunkten des Chips leitend verbunden, so daß hierüber die Kommunikation der Chipkarte mit entsprechenden Geräten (Chipkartenterminals) ermöglicht wird. Das Chipmodul wird in einer zur Kartenvorderseite hin offenen Aussparung des Kartenkörpers fixiert. Die Kontakte liegen in der Ebene der Kartenvorderseite oder minimal (ca. ± 0,1 mm) gegenüber dieser versetzt.The The invention relates to a contact-type chip card. such Smart cards contain a chip module, i. a carrier element for the chip / IC module, with electrically conductive Contacts. These contacts are with appropriate connection points the chip conductively connected, so that on this the communication of the smart card with appropriate devices (Chip card terminals) allows becomes. The chip module is in an open towards the front of the card Fixed recess of the card body. The contacts are in the plane of the front of the card or minimal (about ± 0.1 mm) with respect to this added.
Derartige Chipkarten haben bereits eine große Verbreitung gefunden in Form von Telefonkarten, Krankenversichertenkarten, GSM-Karten, Bank- und Kreditkarten etc.such Smart cards have already found widespread use in Form of telephone cards, health insurance cards, GSM cards, bank cards and credit cards etc.
Das Layout dieser Karten (Kartenvorderseite und Rückseite) ist in aufwendiger Weise, meistens mehrfarbig gestaltet; wohingegen momentan nur Chipmodule mit einer gold- oder silberfarbenen Oberfläche der Kontakte verfügbar sind. Dabei sind diese Kontakte meistens so aufgebaut, daß auf eine Kupferschicht eine Metallisierung aus Gold, Silber oder Palladium aufgebracht wird, wobei auch die Palladium-Metallisierung silberfarben erscheint. Die Dicke der Metallisierung ist dabei so groß, daß das darunter befindliche Kupfer nicht mehr sichtbar ist und die Farbe der Kontakte der Metalleigenfarbe der aufgebrachten Metallisierung entspricht.The Layout of these cards (card front and back) is more elaborate Manner, mostly multicolored; whereas currently only chip modules with a gold or silver-colored surface the contacts available are. These contacts are usually constructed so that on a copper layer a metallization of gold, silver or palladium applied is, where the palladium metallization appears silver. The thickness of the metallization is so great that the underlying Copper is no longer visible and the color of the contacts of the metal color the applied metallization corresponds.

Die Herstellung der letzten Ausführungsform ist relativ aufwendig und damit kostenungünstig.The Production of the last embodiment is relatively expensive and thus cost-effective.
Aufgabe der Erfindung ist es, eine kontaktbehaftete Chipkarte zu schaffen, deren Kontakte bei Betrachtung unter weißem Licht in Abhängigkeit vom Betrachtungswinkel und/oder der Ausrichtung der Karte zum einfallenden Licht in verschiedenen Regenbogenfarben erscheinen und deren Herstellung einfach und damit kostengünstig ist.task The invention is to provide a contact-type chip card, their contacts when viewed under white light depending from the viewing angle and / or orientation of the card to the incident Light in different rainbow colors appear and their manufacture easy and therefore cost-effective is.
Die der Erfindung zugrunde liegende Idee ist, die Oberfläche der Kontakte so auszubilden, daß das Phänomen der Lichtinterferenz zum Tragen kommt. Infolge von Lichtinterferenz wird beispielsweise das „weiße" Sonnenlicht in seine spektralen Bestandteile – die Regenbogenfarben – aufgefächert.The The idea underlying the invention is the surface of the Form contacts in such a way that the phenomenon of Light interference comes into play. As a result of light interference For example, the "white" sunlight in his spectral components - the Rainbow colors - fanned out.
Dieses Phänomen ist z.B an dünnen Seifenlamellen oder Ölfilmen beobachtbar, die infolge der sogenannten „Interferenz an dünnen Schichten" vielfarbig schillernd erscheinen.This phenomenon is for example thin Soap lamellae or oil films observable, shimmering in many colors due to the so-called "interference on thin layers" appear.
In etwas abgewandelter Form ist dieses Phänomen auch an Schmetterlingen beobachtbar, wo die schillernden Farben der Schmetterlinge infolge einer sogenannten „Vielstrahlinterefenz" an einer mikroskopisch kleinen, schuppenartigen Struktur auf den Flügeln entstehen.In In a slightly modified form, this phenomenon is also true of butterflies observable, where the dazzling colors of the butterflies result a so-called "Vielstrahlinterefenz" at a microscopic small, scale-like structure arise on the wings.
An Hand der beigefügten Zeichnungen soll die Erfindung nachfolgend näher beschrieben werden.At Hand of the attached Drawings, the invention will be described in more detail below.

Für den Gangunterschied (Delta) benachbarter Strahlen gilt: Destruktive Interferenz ergibt sich immer dann, wenn der Gangunterschied ein ungeradzahliges Vielfaches der halben Wellenlänge ist.For the path difference (delta) of neighboring beams: Destructive interference always occurs when the path difference is an odd multiple of half the wavelength.
Ein bestimmter Farbton entsteht dabei durch destruktive Interferenz der Komplementärfarbe.One certain color is created by destructive interference the complementary color.
