Description

Die vorliegende Erfindung betrifft einen Sicherheits-Abdeckaufkleber, insbesondere zur Abdeckung einer auf einer Guthabenkarte, wie Handy-Telefonkarte, angebrachten Zeichenfolge, wie PIN-Code, die allein zur Kenntnisnahme durch einen bestimmten berechtigten Nutzer vorgesehen ist, wobei der Abdeckaufkleber eine durchsichtige Folienschicht, eine unterseitige Klebstoffschicht, eine oberseitige undurchsichtige, manuell entfernbare Rubbelschicht und ein unberechtigtes Ablösen erkennbar machende Sicherheitsmerkmale aufweist.The present invention relates to a security cover sticker, especially to cover one a credit card, such as a cell phone phone card String, such as PIN code, for your information only provided by a certain authorized user is, the cover sticker is a transparent Film layer, an underside adhesive layer, a opaque, manually removable scratch layer on top and identifying unauthorized detachment Has security features.

Sicherheits-Abdeckaufkleber der genannten Art sollen eine auf einer Guthabenkarte oder sonstigen Dokument angebrachte Zeichenfolge solange verdecken, bis der bestimmte berechtigte Nutzer der Karte oder des Dokuments diese(s) in seinen Besitz bekommt. Durch Abrubbeln der Rubbelschicht kann dann der berechtigte Nutzer die Zeichenfolge sichtbar machen und beispielsweise als Identifikationsnummer in sein Handy oder ein anderes, mit einer Guthabenkarte gekoppeltes Gerät eingeben. In der Vergangenheit mußten aber sowohl Nutzer als auch Dienstleistungsanbieter, die derartige Guthabenkarten benutzen bzw. zur Verfügung stellen, feststellen, daß ein Mißbrauch derartiger Guthabenkarten mit relativ geringem Aufwand und zumindest für Laien nicht erkennbar möglich ist. Der Mißbrauch besteht insbesondere darin, daß unbefugte Personen die Rubbelschicht entfernen, um Kenntnis von der darunter verborgenen Zeichenfolge zu erlangen und dann die Guthabenkarte für ihre Zwecke zu nutzen. Nach Verbrauch des Guthabens wurde dann eine neue Rubbelschicht aufgetragen, so daß die Guthabenkarte nach außen hin einen unversehrten Eindruck machte. Diese vorab entleerten Guthabenkarten wurden an gutgläubige Nutzer verkauft, die dann feststellen mußten, daß die Guthabenkarte kein Guthaben enthielt.Safety cover stickers of the type mentioned are said to be one affixed to a credit card or other document Conceal the string until the specific one Authorized users of the card or the document (s) gets into his possession. By rubbing off the scratch layer the authorized user can then use the string make it visible and, for example, as an identification number into his cellphone or another, with one Enter the credit card of the paired device. In the past but both users and service providers, who use such prepaid cards or make available, find that an abuse such prepaid cards with relatively little Effort and at least not recognizable to laypeople is. The abuse is particularly that unauthorized People remove the scratch layer for knowledge to get from the hidden string and then use the prepaid card for their purposes. After the credit was used up a new scratch layer applied so that the credit card after made an intact impression on the outside. This pre-emptied credit cards were sent to good faith Users sold, who then found that the Credit card contained no credit.

Aus der DE 197 05 380 C1 ist ein Sicherheits-Abdeckaufkleber der eingangs genannten Art und für den vorstehend erläuterten Verwendungszweck bekannt, wobei ein Teil der. beschriebenen Probleme mit diesem Aufdeckaufkleber schon gelöst wird. Bei diesem bekannten Abdeckaufkleber sind die ein unberechtigtes Ablösen erkennbar machenden Sicherheitsmerkmale als Sicherheitsstanzung ganzflächig in der Folienschicht ausgeführt. Die Rubbelschicht ist hier eine gefärbte Haftkleberschicht. Nachteilig ist bei diesem Abdeckaufkleber, daß die Herstellung wegen der in der Folienschicht anzubringenden ganzflächigen Sicherheitsstanzung aufwendig und dadurch teuer ist. Außerdem Wird durch die Sicherheitsstanzung die Handhabung des Sicherheits-Abdeckaufklebers vor und während seiner Anbringung am dafür vorgesehenen Anbringungsort erschwert, weil der Abdeckaufkleber sehr empfindlich gegen Biegebeanspruchungen ist. Dabei kann es sehr leicht zu einem Bruch der Folienschicht kommen, bevor der Abdeckaufkleber überhaupt zur Verwendung kommt. Durch die Verwendung einer Haftkleberschicht als Rubbelschicht besteht zumindest die Gefahr, daß bei Lagerung mehrerer Abdeckaufkleber übereinander oder bei Lagerung von mit diesen Abdeckaufklebern versehenen Karten oder Blättern die Haftkleberschicht in unerwünschter Weise an einer auf ihr liegenden Schicht einer Karte oder eines sonstigen Dokuments haftet. Beim Trennen kann es dann dazu kommen, daß unbeabsichtigt die Haftkleberschicht beschädigt wird. DE 197 05 380 C1 is a security cover sticker of the type mentioned and for the above known use is known, part of the. already described problems with this cover sticker is solved. In this known cover sticker are the security features that make an unauthorized detachment recognizable as a safety punch all over in of the film layer. The scratch layer is here a colored layer of pressure sensitive adhesive. The disadvantage of this Cover stickers that the manufacture because of the in full-surface safety punching to be applied to the film layer is complex and therefore expensive. Moreover Is the handling of the Safety masking sticker before and during its application difficult at the intended location, because the cover sticker is very sensitive to bending stress is. It can very easily become one Break the film layer come before the cover sticker is used at all. By using it there is at least one pressure-sensitive adhesive layer as a scratch layer the risk that when storing several cover stickers one above the other or when storing with these cover stickers provided cards or sheets the layer of pressure sensitive adhesive in an undesirable way on one on it lying layer of a card or other document liable. When disconnecting, it can happen that the pressure-sensitive adhesive layer is inadvertently damaged.

Für die vorliegende Erfindung stellt sich deshalb die Aufgabe, einen Sicherheits-Abdeckaufkleber der eingangs genannten Art zu schaffen, der die dargelegten Nachteile vermeidet und bei dem gewährleistet ist, daß jede Manipulation, insbesondere jeder Versuch einer Kenntnisnahme der unter dem Abdeckaufkleber angebrachten Zeichenfolge durch Anheben des Aufklebers oder durch Entfernen der Rubbelschicht eindeutig und auch für Laien auf den ersten Blick erkennbar wird und bei dem Herstellung und Handbabung zwar vereinfacht, aber doch gegen Mißbrauch gesichert sind.Therefore, for the present invention Task, a security cover sticker of the beginning mentioned type to create the disadvantages set out avoiding and ensuring that any manipulation, in particular every attempt to gain knowledge the string under the cover sticker by lifting the sticker or by removing the Scratch layer clearly and also for laypersons at first Is recognizable and in the manufacture and Handbabung simplified, but against abuse are secured.

Die Lösung dieser Aufgabe gelingt durch einen Sicherheits-Abdeckaufkleber der eingangs genannten Art, der dadurch gekennzeichnet ist,

  • daß die Folienschicht in einem ein Feld von mindestens der Größe der Zeichenfolge rahmenförmig umgebenden Bereich als sogenannte Voidfolie, die nach einem einmaligen Abheben eine dauerhaft erkennbare, irreversible optische Veränderung aufweist, ausgeführt ist,
  • daß die Rubbelschicht eine Rubbellackschicht ist, die zumindest das von dem rahmenförmigen Bereich umgrenzte fensterförmige Feld der Folienschichtoberseite bedeckt und
  • daß auf die Rubbellackschicht und ggf. auf einen diese umgebenden Bereich der Oberseite der Folienschicht mit einer nur unter UV-Licht sichtbaren Farbe und/oder mit einer zum Farbton der Rubbellackschicht kontrastierenden unmittelbar sichtbaren Farbe (je) ein Druckbild in Form von grafischen Mustern und/oder Zeichen aufgebracht ist.
This problem is solved by a security cover sticker of the type mentioned at the beginning, which is characterized in that
  • that the film layer is designed as a so-called void film in an area surrounding a field at least the size of the character string, which after a single lift has a permanently recognizable, irreversible optical change,
  • that the rubbing layer is a rubbing lacquer layer which covers at least the window-shaped field of the film layer top delimited by the frame-shaped area and
  • that a print image in the form of graphic patterns and / or on the area of the top of the film layer with a color that is only visible under UV light and / or with an immediately visible color that contrasts with the color of the layer of scratch layer or sign is applied.

Durch die teilflächige Ausführung der Folienschicht als Voidfolie wird gewährleistet, daß jedes Abheben der Folienschicht von der Guthabenkarte oder vom sonstigen Dokument optisch erkennbar wird und auch nach einem erneuten Andrücken des Aufklebers weiterhin deutlich sichtbar und damit unumkehrbar bleibt. Durch die weiterhin vorgesehene Rubbellackschicht bleibt andererseits für den berechtigten Nutzer die Handhabung der Guthabenkarte genauso, wie er es bisher gewohnt ist, so daß hier keine Umstellung der Benutzer erforderlich ist. Die außerdem angegebenen Druckbilder aus UV-Farbe und/oder einer Kontrastfarbe sind zusätzliche, eine Wiederherstellung des Abdeckaufklebers nach einer Manipulation mit Entfernen der Rubbellackschicht oder eine Fälschung erschwerende Merkmale. Damit bietet der erfindungsgemäße Sicherheits-Abdeckaufkleber einerseits eine hohe Sicherheit gegen Manipulationen mit dem Zweck einer unbefugten Kenntnisnahme der darunter angebrachten Zeichenfolge und zum anderen eine hohe Sicherheit gegen unbefugte Nachahmung. Damit wird ein hohes Sicherheitsniveau sowohl für die Nutzer derartiger Karten als auch für die Dienstleister, die diese Karten ausgeben, erreicht. Schließlich ist es für den Hersteller der Abdeckaufkleber vorteilhaft, daß keine teure und aufwendige Stanzung mehr nötig ist.Due to the partial execution of the film layer as Void film ensures that each time the film layer is lifted off from the prepaid card or other document becomes optically recognizable and even after a new one Pressing on the sticker remains clearly visible and so that it remains irreversible. Through the still provided Scratch coating layer, on the other hand, remains for the justified Users handling the prepaid card as well, as he is used to so far, so no change here the user is required. The also specified Print images from UV color and / or a contrasting color are additional, a restoration of the cover sticker after manipulation with removal of the Scratch layer or a counterfeiting aggravating characteristics. The security cover sticker according to the invention thus offers on the one hand a high level of security against manipulation with the purpose of unauthorized access the string underneath and the other a high level of security against unauthorized copying. In order to will be a high level of security for both users such cards as well as for the service providers who spend those cards, reached. After all, it is for the manufacturer of the cover sticker advantageous that none expensive and complex punching is more necessary.

Eine Weiterbildung des Sicherheits-Abdeckaufklebers ist im Anspruch 2 angegeben, wobei diese Ausführung des Abdeckaufklebers insbesondere dafür sorgt, daß ein einmaliges Abheben optisch besonders deutlich erkennbar wird, ohne daß dafür die Oberfläche der Karte, auf der der Abdeckaufkleber angebracht ist, eine besondere Farbgebung haben muß, und daß andererseits die auf der Karte angebrachte Zeichenfolge nach Entfernen der Rubbellackschicht deutlich erkennbar bleibt. Wenn die Klebstoffschicht nur auf die Unterseite der unteren Farbschicht aufgebracht ist, kann die Klebstoffschicht auch aus einem nicht durchsichtigen Material bestehen; wenn die Klebstoffschicht zusätzlich auch auf die Unterseite des Feldes der Folienschicht aufgebracht ist, muß die Klebstoffschicht durchsichtig sein, um die auf der Karte angebrachte Zeichenfolge von oben nach dem Abrubbeln der Rubbellackschicht durch die Folienschicht und die Klebstoffschicht hindurch ablesen zu können.A further development of the security cover sticker is indicated in claim 2, wherein this embodiment of the cover sticker especially ensures that a one-off Take off is visually particularly clearly recognizable, without the surface of the card, on which the cover sticker is appropriate, a special coloring and that, on the other hand, the one on the card String after removing the scratch card layer remains clearly recognizable. If the adhesive layer only on the underside of the lower layer of paint is applied, the adhesive layer can also consist of a non-transparent material; if the Adhesive layer also on the underside of the Field of the film layer is applied, the adhesive layer be transparent to the ones on the card String from above after rubbing off the Scratch lacquer layer through the film layer and the adhesive layer to be able to read through.

Weiterhin kann auf den Sicherheits-Abdeckaufkleber oberseitig in einer unmittelbar sichtbaren Farbe eine Informationsangabe, insbesondere eine fortlaufende Aufkleber-Nummer, in Ziffern und/oder als Strichcode aufgedruckt sein. Hierdurch wird zusätzlich die Möglichkeit geschaffen, bestimmte Karten und bestimmte Sicherheits-Abdeckaufkleber einander zuzuordnen und nachträglich noch festzustellen, ob der vom berechtigten Nutzer der Karte vorgefundene Abdeckaufkleber auch tatsächlich zu dieser Karte gehört.Furthermore, the top of the safety cover sticker can be used information in an immediately visible color, especially a consecutive sticker number, printed in numbers and / or as a barcode his. This also creates the opportunity certain cards and certain security cover stickers assign them to each other and subsequently determine whether the one found by the authorized user of the card Cover stickers actually go with this Card heard.

Um die auf der Karte angebrachte Zeichenfolge auch gegen eine unbefugte Erkennung mittels Durchleuchtens der Karte zu sichern, ist bevorzugt vorgesehen, daß die Rubbellackschicht durch eine Metalleffekt-Farbe gebildet ist. Eine Metalleffekt-Farbe hat eine besonders starke Deckwirkung und unterbindet einen Lichtdurchtritt, mit dem die Zeichenfolge erkennbar gemacht werden könnte.Against the string on the card unauthorized detection by scanning the card To secure, it is preferably provided that the scratch card layer is formed by a metallic effect color. A metallic effect color has a particularly strong covering effect and prevents the passage of light with which the string could be made recognizable.

Eine zusätzliche Erschwerung einer unbefugten Kenntnisnahme der Zeichenfolge kann dadurch erreicht werden, daß das in einer zur Rubbellackschicht kontrastierenden unmittelbar sichtbaren Farbe aufgebrachte Druckbild ein Bild aus statistisch zufällig verteilten Zeichenbruchstücken und/oder Schlängellinien und/oder dergleichen Muster ist.An additional aggravation of unauthorized access the string can be achieved in that that in a direct contrast to the scratch-off layer visible color applied printed image Image from randomly distributed fragments of characters and / or meandering lines and / or the like Pattern is.

Besonders geeignete Kunststoffmaterialien zur Bildung der Folienschicht sind im Anspruch 6 angegeben.Particularly suitable plastic materials for education the film layer are specified in claim 6.

Um dem die Guthabenkarten herstellenden Betrieb oder dem die Guthabenkarten ausgebenden Dienstleister die Handhabung der Sicherheits-Abdeckaufkleber zu erleichtern und eine automatisierte Anbringung zu ermöglichen, ist vorgesehen, daß der Sicherheits-Abdeckaufkleber vor seiner Anbringung auf einer Guthabenkarte oder dergleichen Dokument einzeln oder zu mehreren auf einem Trennpapier, insbesondern Silikon-Liner, lösbar haftend angeordnet ist.To the company producing the credit cards or the service providers issuing prepaid cards the safety cover sticker to facilitate and automated attachment is provided, that the security masking sticker is attached before it is attached on a prepaid card or similar document individually or in pairs on a release paper, in particular Silicone liner, is arranged releasably adhesive.

Speziell für eine automatisierte Handhabung und Anbringung der Sicherheits-Abdeckaufkleber ist vorgesehen, daß das Trennpapier als Streifen oder Rolle mit einer Anzahl von fortlaufend numerierten Abdeckaufkleber ausgeführt ist. Vorteilhaft für die automatisierte Handhabung und Anbringung der Abdeckaufkleber ist auch deren wegen des Fehlens einer Sicherheitsstanzung besonders geringe Bruchempfindlichkeit.Especially for automated handling and application the safety cover sticker is provided that the release paper as a strip or roll with a number of sequentially numbered cover stickers is. Advantageous for automated handling and Attaching the cover sticker is also because of the The lack of a security punching is particularly low Fracture sensitivity.

Als nächste Schicht folgt nach unten hin eine Farbschicht 22, die teils unmittelbar an der Unterseite der Folienschicht 2 und teils an der Unterseite der Voidpartikel 21 haftet. Dabei ist die Haftung zwischen der Unterseite der Folienschicht 2 und der Farbschicht 22 stark, während die Haftung zwischen der Unterseite der Folienschicht 2 und den Voidpartikeln 21 schwach ist.The underside of the film layer 2 is in the frame-shaped Area 2 'with a print image of void particles 21 provided, the print image characters or numbers or can represent any pattern. As the next layer is followed by a layer of paint downwards 22, some of which are directly on the underside of the film layer 2 and partly on the underside of the void particles 21 is liable. The liability is between the bottom the film layer 2 and the color layer 22 strong while the adhesion between the bottom of the film layer 2 and the void particles 21 is weak.

Als nach unten hin letzte Schicht schließt sich eine vollflächige Klebstoffschicht 23 aus einem durchsichtigen Klebstoff an. Mit dieser Klebstoffschicht 23 ist der Sicherheits-Abdeckaufkleber 1 haftend auf dem Trennpapier 4 angebracht, das vorzugsweise die Form von langen Streifen oder Rollen hat.As the last layer down, one closes full-surface adhesive layer 23 made of a transparent Adhesive. With this adhesive layer 23 Safety cover sticker 1 adheres to the release paper 4 attached, which is preferably the shape of long Has stripes or rolls.

Figur 3 zeigt den Sicherheits-Abdeckaufkleber 1 in einem zweiten Querschnitt, nun entlang der Linie III-III in Figur 1, die durch das mittlere Feld 2'' der Folienschicht 2 verläuft. Wie Figur 3 verdeutlicht, sind im Bereich des Feldes 2'' keine Voidpartikel 21 vorgesehen; auch ist hier die Farbschicht 22 ausgespart. Im Bereich des Feldes 2'' ist also der Sicherheits-Abdeckaufkleber 1 nach Entfernung der Rubbellackschicht 20 und mit ihr des Druckbildes 24, 25 durchsichtig, wie dies für den eingangs dargelegten Verwendungszweck erforderlich ist. Der in Figur 3 nicht von den Voidpartikeln 21 und der Farbschicht 22 belegte Bereich ist von der Klebstoffschicht 23 ausgefüllt. Ganz unten in Figur 3 ist wieder das Trennpapier 4 sichtbar.Figure 3 shows the security cover sticker 1 in one second cross-section, now along the line III-III in Figure 1, through the middle field 2 '' of the film layer 2 runs. As shown in Figure 3, are in No void particles 21 are provided in the area of the field 2 ″; here too the color layer 22 is left out. In the area of field 2 '' is the safety cover sticker 1 after removal of the scratch coating layer 20 and with it of the printed image 24, 25 transparent, as is the case for the is initially required. The one in FIG. 3 not of the void particles 21 and the Color layer 22 occupied area is from the adhesive layer 23 filled out. At the very bottom in Figure 3 is again the release paper 4 visible.

Figur 4 der Zeichnung zeigt schließlich den Sicherheits-Abdeckaufkleber 1 nach seiner Anbringung auf einer Guthabenkarte 5 oder dergleichen Dokument und nachdem die Rubbellackschicht 20 zusammen mit dem darauf befindlichen Druckbild 24, 25 manuell entfernt ist. Dieses manuelle Entfernen der Rubbellackschicht 20 wird vom Benutzer der Guthabenkarte 5 dann vorgenommen, wenn er die Karte erworben hat, um eine auf der Oberfläche der Karte 5 angebrachte Zeichenfolge 50 ablesen zu können. In dem in Figur 4 gezeigten Zustand des Abdeckaufklebers 1 ist das Ablesen der Zeichenfolge 50 ohne weiteres möglich, weil die nun freigelegte Folienschicht 2 durchsichtig ist und weil auch die Klebstoffschicht 23 ebenso durchsichtig ist.Figure 4 of the drawing finally shows the security cover sticker 1 after it has been attached to a prepaid card 5 or the like document and after that Rubbellackschicht 20 together with that on it Print image 24, 25 is removed manually. This manual Removal of the scratch coating layer 20 is done by the user the prepaid card 5 made when he the Card has purchased one on the surface of the card 5 attached string 50 to be able to read. By doing state of the cover sticker 1 shown in FIG the reading of the character string 50 is readily possible, because the now exposed film layer 2 is transparent and because the adhesive layer 23 is also transparent is.

Ein unbefugtes Ablesen der Zeichenfolge 50 könnte entweder durch Entfernen der Rubbellackschicht 20 und erneutes Auftragen einer Rubbellackschicht oder durch komplettes Abheben des Sicherheits-Abdeckaufklebers 1 und erneutes Anbringen erfolgen. Wenn auf die erstgenannte Art und Weise eine Manipulation vorgenommen würde, müßte nicht nur die Rubbellackschicht 20, sondern auch das darauf aufgebrachte Druckbild 24, 25 aus einer nicht unmittelbar sichtbaren UV-Farbe und/oder einer kontrastierenden, unmittelbar sichtbaren Farbe wiederhergestellt werden, was nur mit einem sehr hohen technischen Aufwand machbar wäre und damit in der Praxis weitgehend ausgeschlossen ist. Wenn auf die zweitgenannte Art und Weise eine unbefugte Person Kenntnis von der Zeichenfolge 50 erlangt haben sollte, wird dies durch die infolge des Abhebens des Abdeckaufklebers 1 eingetretene, dauerhaft erkennbare, irreversible optische Veränderung seines rahmenförmigen Bereiches 2' erkennbar. Wenn nämlich der Abdeckaufkleber 1 angehoben wird, erfolgt in dessen Innerem eine Trennung, wobei in den Bereichen, in denen die Voidpartikel 21 vorgesehen sind, sich die Folienschicht 2 von diesen löst, während sie in den Bereichen, in denen keine Voidpartikel 21 vorgesehen sind, mit der Farbschicht 22 und der darunter liegenden Klebstoffschicht 23 verbunden bleibt. Hierdurch wird die Farbschicht 22 in sich zerstört, wobei diese Zerstörung durch ein erneutes Andrücken des Abdeckaufklebers 1 nicht wieder rückgängig gemacht werden kann, sondern vielmehr nach außen hin durch die Folienschicht 2 hindurch erkennbar bleibt. Wenn die Oberseite der Folienschicht 2 vollflächig mit der Rubbellackschicht 20 bedeckt ist, wird die Veränderung in der Farbschicht 22 spätestens nach Entfernen der Rubbellackschicht 20 sichtbar; wenn, wie beim dargestellten Ausführungsbeispiel, die Rubbellackschicht 20 nur im Bereich des Feldes 2'' auf die Oberseite der Folienschicht 2 aufgebracht ist, was für die Funktion des Abdeckaufklebers 1 ausreicht, dann wird die Veränderung innerhalb der Farbschicht 22 schon sofort sichtbar, ohne daß die Rubbellackschicht 20 erst entfernt werden muß.Unauthorized reading of string 50 could either by removing the scratch coating layer 20 and again Apply a layer of scratch paint or by complete Lift off the safety cover sticker 1 and again Attachment done. If in the first way and how a manipulation would be carried out not only the rubbing lacquer layer 20, but also that on top of it applied print image 24, 25 from a not immediately visible UV color and / or a contrasting, immediately visible color are restored, what only with a very high technical effort would be feasible and thus largely excluded in practice is. If in the second way an unauthorized person is aware of the string 50 should have obtained this is due to the result of the take off of the cover sticker 1, permanently recognizable, irreversible optical change to its frame-shaped Area 2 'recognizable. If namely the cover sticker 1 is raised, takes place inside it a separation, being in the areas where the Void particles 21 are provided, the film layer 2 of these triggers while in the areas where no void particles 21 are provided with the color layer 22 and the underlying adhesive layer 23 remains connected. As a result, the color layer 22 destroyed in itself, this destruction by a new one Pressing on the cover sticker 1 does not undo can be made, but rather to the outside remains recognizable through the film layer 2. If the top of the film layer 2 with the entire surface the rubbing layer 20 is covered, the change in the color layer 22 at the latest after removing the Rubbellackschicht 20 visible; if, like the one shown Embodiment, the scratch card layer 20 only in Area of field 2 '' on top of the film layer 2 is applied, which is for the function of the cover sticker 1 is sufficient, then the change immediately visible within the color layer 22 without that the scratch coating layer 20 must first be removed.
