Abstract
Description
Mit modernen Farbkopiergeräten ist es auch möglich, VorlagenWith modern color copiers it is also possible to make templates
und damit auch Geldscheine form- und farbidentisch auf beliebige Papiersorten bis in kleinste Einzelheiten genau und kurzfristig zu kopieren. Damit besteht die Möglichkeit, durch wilikürliche Verteilung von Geldschein-Falsifikate mindestens das Vertrauen in den bestehenden Geldverkehr erheblich zu stören bzw. zu eigenen illegalen Zwecken auszunutzen.and thus also banknotes with identical shapes and colors on any type of paper to copy down to the smallest details exactly and at short notice. So there is the Possibility by random distribution of counterfeit banknotes at least to significantly disrupt or to own the trust in the existing monetary transactions exploiting illegal purposes.
Das Prinzip eines fälschungssicheren Zahlungsmittels basiert auf der Forderung, Risiko und Aufwand für das Unterlaufen der Vertrauensschwelle des allgemeinen Verkehrs zu hoch zu machen, daß die Herstellung von Falsifikaten unrentabel wird. Diese Forderung wurde bisher dadurch erfüllt, daß Geldscheine von Spezialgraphikern z. B. mit maschinellen Guillochen versehen wurden, die auf das gesamte Bild abgestellt wurden. Solche Gravuren sind von Hand außerordentlich schwer zu immitieren. Eine andere, meist zusätzliche Möglichkeit ist der Einbau von Metallstreifen in das Papier, die Auswahl besonderer Papiersorten und die Verwendung von Wasserzeichen.The principle of a forgery-proof means of payment is based on the Demand, risk and effort for undermining the general trust threshold To make traffic too high that the production of counterfeit goods becomes unprofitable. This requirement has hitherto been met by using banknotes from specialty graphic artists z. B. were provided with machine guilloches, which are based on the entire picture became. Such engravings are extremely difficult to imitate by hand. One another, usually additional option is the installation of metal strips in the paper, the selection of special types of paper and the use of watermarks.
Mit modernen Farbkopiergeräten ist es jedoch möglich, Farbkopien herzustellen, die mit dem Original bis auf die Wasserzeichen praktisch identisch sind. Normalerweise liegt die Vertrauensschwelle des Verkehrs so hoch, daß auf Wasserzeichen, ja noch nicht einmal auf Papierqualität und eingelegte Metallfäden sonderlich geachtet wird, es sei denn in den Banken bei der Entgegennahme von Schaltergeldern.However, with modern color copiers it is possible to make color copies, which are practically identical to the original except for the watermarks. Normally the confidence threshold of the traffic is so high that on watermarks, yes still not even the paper quality and the inserted metal threads are given special attention, unless in the banks when accepting counter money.
Verschlimmert wird die Situation noch dadurch, daß bei Einsatz moderner Farbkopiergeräte praktisch keinerlei Mengenbeschränkungen bestehen und auch hinsichtlich des Einsatzes von geeigneten Papierqualitäten weiteste Spielräume bestehen.The situation is made even worse by the fact that with the use of modern Color copiers practically no quantity restrictions exist and also with regard to the use of suitable paper grades has the greatest possible leeway.
Ein weiteres Problem besteht darin, daß Geldscheine mit Hilfe von Farbkopiergeräten in den verschiedensten Denominationen kopiert werden können. Damit kann jeder Schein praktisch verdoppelt und verdreifacht werden, ohne daß durch häufiges Auftreten gleicher Denominationen das Augenmerk Prüfender auf die Existenz von Falsifikaten gelenkt wird. Auch das Einkreisen von Falsifikaten durch Veröffentlichungen von -Fehlern in den Falsifikaten ist durch die Anwendung modernster Farbkopiergeräte nicht mehr möglich.Another problem is that banknotes can be transferred with the help of Color copiers copied in various denominations will can. This means that each bill can practically be doubled and tripled without that by frequent occurrence of the same denominations the attention of examiners on the existence of counterfeit certificates is directed. Also the circling of counterfeit certificates by publishing errors in the falsified documents is through the application state-of-the-art color copiers are no longer possible.
Die Erfindung löst die aufgezeigten Probleme durch ein fälschungssicheres Zahlungsmittel in Münz- oder Scheinform, das bei Berührung wenigstens in einem Teilbereich eine reversible, sinnlich, vorzugsweise optisch wahrnehmbare Veränderung erfährt.The invention solves the problems identified by a forgery-proof one Means of payment in the form of coins or notes, which when touched at least in a partial area undergoes a reversible, sensual, preferably optically perceptible change.
Die Erfindung ist dabei, wie oben angegeben, nicht auf Scheine als Zahlungsmittel beschränkt, sondern kann sich auch auf Münzen erstrecken, die nunmehr z. B. aus einfachem Kunststoff hergestellt werden können.The invention is, as stated above, not on bills as Means of payment are limited, but can also extend to coins that are now z. B. can be made of simple plastic.
Das erfindungsgemäße Zahlungsmittel läßt sich beispielsweise dadurch herstellen, daß wenigstens in einem Teilbereich in das Schein- oder Münzmaterial Kristalle eingebaut werden, die bei Berührung infolge Druck- und/oder Wärmeeinwirkung zu einem Farbumschlag führen. Solche Zahlungsmittel können zwar ebenfalls auf modernen Farbkopiergeräten kopiert werden, weisen jedoch eine Eigenschaft auf, die dem Kopierer nicht zugängig ist, nämlich den Farbumschlag bei Berührung infolge Wärme- oder Druckeinwirkung. Geht das erfindungsgemäße Zahlungsmittel von Hand zu Hand, kann der Empfangende jederzeit am Verschwinden des Farbumschlages an der Stelle, wo der Gebende das Zahlungsmittel in der Hand hielt und am Auftauchen des Farbumschlages an der Stelle, wo er das Geldmittel in Empfang nimmt, die Echtheit des Geldmittels feststellt.The means of payment according to the invention can, for example, thereby produce that at least in a partial area in the bill or coin material Crystals are built in, which when touched as a result of pressure and / or heat lead to a color change. Such means of payment can also be used on modern Color copiers are copied, however, have one property that is common to the copier is not accessible, namely the color change when touched as a result of heat or pressure. If the means of payment according to the invention goes from hand to hand, the recipient can at any time on the disappearance of the color change at the point where the giver has the means of payment in his hand and the appearance of the color change at the point where he said Receives funds, verifies the authenticity of the funds.
Zu sinnlich wahrnehmbaren Veränderungen gehören auch bei Berührung auftretende, reversible Kräuselungen vorgegebener Formgebung o. dgl.Sensually perceptible changes also include touch Occurring, reversible crimps of a given shape or the like.
Solche Zahlungsmittel lassen sich ohne Schwierigkeiten aus mehreren Folien herstellen, die zu mehreren übereinandergelegt werden und in denen an geeigneter Schichthöhe die entsprechenden Kristalle o. dgl. eingelagert sind. Dadurch ergibt sich auch die Möglichkeit, noch weitere Einrichtungen in die Schichten einzulagern, die beispielsweise in den Banken die Zählmöglichkeit auf der Basis elektronischer Zählung erleichtern. Außerdem sind aus Kunststoff bestehende Zahlungsmittel wegen der Vielfalt moderner Kunststoffe, die z. T. ausgesprochen bakterienfeindlich sind, auch wesentlich hygienischer.Such means of payment can be easily selected from several Produce foils, which are placed on top of each other and in which more suitable Layer height the corresponding crystals or the like are embedded. This results in there is also the option of storing additional equipment in the shifts, which, for example, in the banks, the possibility of counting on the basis of electronic Make counting easier. In addition, existing plastic means of payment are due the variety of modern plastics that z. T. are extremely hostile to bacteria, also much more hygienic.
In der Zeichnung bedeuten 1 und 2 gegebenenfalls mit Aufdrucken versehene Deckschichten und 3 eine Zwischenschicht mit eingelagerten Kristallen 4 die bei Druck in der Farbe umschlagen, bei Aufhören des Druckes aber wieder die Ursprungsfarbe annehmen.In the drawing, 1 and 2 denote optionally provided with imprints Cover layers and 3 an intermediate layer with embedded crystals 4 in the The color of the print changes, but when the print stops, the original color returns accept.
Die Ausbildung solcher Zahlungsmittel ist erkennbar relativ schwierig.The formation of such means of payment is obviously relatively difficult.
Insbesondere können sie aber allein durch Kopieren mit einem der modernen Farbkopiergeräte nicht nachgemacht werden.In particular, you can copy it with one of the modern Color copiers cannot be copied.
