Abstract

The invention relates to a card-like transponder ticket which comprises a shielding covering (1) which is made of a plastic metal composite film having a void effect. The conductive components in the covering (1) shield the transponder arrangement, and also make it impossible or very hard to carry out unauthorised and/or unintentional reading, writing or erasing of the transponder chip (8). The covering (1), which is represented by a crosshatch, is coated on the lower side with an adhesive (4), except in the region of the tab (3). A lower-sided adhesive free corner of the covering (1) is embodied as a tab (3). Said transponder arrangement comprises an antenna (7) and a transponder chip (8). It is covered with a plastic protection layer which prevents parts of the transponder arrangement from remaining on the adhesive layer (4) when the covering (1) is removed. A void effect is produced when the covering (1) is removed, i.e. lettering (9) become visible. Said void effect is irreversible, i.e. the lettering (9) can no longer disappear. The removal of the covering (1) can also act as a detection for the initial use thereof.

Description

TRANSPONDERETIKETT TRANSPONDER LABEL
Die vorliegende Erfindung betrifft ein Transponderetikett.The present invention relates to a transponder label.
Unter einem Transponderetikett wird im folgenden jegliche flache, einen (grundsätzlich beliebig gearteten) Träger und eine Transponderanordnung umfassende Vorrichtung bezeichnet. Neben selbstklebenden Etiketten somit auch Karten (sogn. Smartcards), flache Anhänger bzw. Anstecker und dgl. mehr. Transponderetiketten werden häufig auch als RFID-Etiketten bezeichnet, wobei RFID als Kurzform von Radio Frequency Identification (Radiofrequenz-Identifizierung) verwendet wird.In the following text, a transponder label refers to any flat device (basically any type) of carrier and transponder arrangement. In addition to self-adhesive labels thus also cards (so-called smart cards), flat pendants or badges and the like. Transponder labels are often referred to as RFID tags, where RFID is used as a short form of Radio Frequency Identification (Radio Frequency Identification).
Transponderetiketten weisen grundsätzlich eine Transponderanordnung mit mindestens einem Speicherchip und einer Antenne auf, wobei letztere üblicherweise im wesentlichen aus einer oder mehreren Leiterschleifen besteht, welche beispielsweise aus einem leitenden Flachmaterial geätzt sein können. Unter Ausnutzung induktiver Effekte können Daten mittels geeigneter Lese-, Schreib- bzw. SchreibVLesegeräte berührungsfrei in den Speicherchip eingelesen bzw. von diesem ausgelesen werden. Entsprechend existieren Transponderetiketten mit Nur-Lese- und Schreib- Lesespeichern.Transponder labels basically have a transponder arrangement with at least one memory chip and an antenna, the latter usually consisting essentially of one or more conductor loops, which may be etched from a conductive flat material, for example. By taking advantage of inductive effects, data can be read into the memory chip without contact or read out by means of suitable read, write or write-on devices. Accordingly, there are transponder labels with read-only and read-write memories.
Transponderetiketten dienen dabei unterschiedlichsten Zwecken, beispielsweise der Identifizierung bzw. Authentifizierung eines menschlichen Trägers, der Überwachung von Produkten während logistischer Abläufe, dem Diebstahlschutz, der Aktenortung uvm. Aufgrund der berührungslosen Datenübertragungsmöglichkeit besteht insbesondere bei sicherheitsrelevanten Anwendungen, wie etwa zur Identifizierung/ Authentifizierung eines menschlichen Trägers das Problem, daß Daten auf Transponderetiketten vor ihrer ersten Anwendung unbefugt ausgelesen und/oder verändert werden können. Somit könnte sich ein unbefugter Dritter unbemerkt eine Kopie wichtiger Zugangsdaten verschaffen, oder Zugangsdaten so verändern, daß dem rechtmäßigen Anwender eine korrekte Identifizierung/ Authentifizierung verwehrt wird.Transponder labels serve a variety of purposes, such as the identification or authentication of a human carrier, the monitoring of products during logistical processes, theft protection, document location and much more. Due to the non-contact data transmission option, in particular in security-relevant applications, such as for identification / authentication of a human carrier, there is the problem that data on transponder labels can be read out and / or changed without authorization prior to their first application. Thus, an unauthorized third party could unnoticed procure a copy of important access data, or change access data so that the legitimate user is denied a correct identification / authentication.
Ferner besteht die Gefahr, daß Daten auf Transponderchips, insbesondere wenn es sich dabei um einen Schreib-Lesespeicher handelt, durch starke magnetische Felder versehentlich unbrauchbar werden.Furthermore, there is a risk that data on transponder chips, especially if it is a read-write memory, become inadvertently unusable due to strong magnetic fields.
Aus US 6,1 21 ,544 ist bekannt, ein Transponderetikett durch Einführen in eine flache Hülle, welche eine Abschirmung aus einer weichmagnetischen Metallegierung aufweist, gegen unbefugten Lesezugriff zu schützen. Eine ähnliche Maßnahme zum Schutz von in Transponderchips gespeicherten Daten ist auch DE 103 17 682 A1 offenbart.From US Pat. No. 6,121,544 it is known to protect a transponder label against unauthorized read access by insertion into a flat envelope having a soft magnetic metal alloy shield. A similar measure for the protection of data stored in transponder chips is also disclosed in DE 103 17 682 A1.
Die bekannten Schutzvorrichtungen für Transponderetiketten eignen sich jedoch nur für den Schutz gegen unbefugtes Auslesen oder Verändern der Daten auf Transponderchips, sobald der Anwender das zu schützende Transponderetikett bei sich trägt. In seiner Abwesenheit bzw. vor Erhalt des Transponderetiketts läßt sich dieses aus der Schutzhülle ziehen, lesen bzw. manipulieren und wieder in die Hülle zurückschieben, ohne daß der rechtmäßige Anwender dies später erkennen könnte.However, the known protection devices for transponder labels are only suitable for protection against unauthorized reading out or changing the data on transponder chips as soon as the user carries the transponder label to be protected. In his absence or before receiving the transponder label can this pull out of the protective cover, read or manipulate and push back into the shell, without the rightful user could recognize this later.
Ferner sind die bekannten Schutzvorrichtungen für die Ausstattung von Massenartikeln, insbesondere Einwegartikeln, wie etwa Eintrittskarten oder Tokens für Abrechnungssysteme in Ferienclubs, Vergnügungsparks und dergleichen, relativ aufwendig, und würden diese oftmals zu kostspielig machen.Furthermore, the known protective devices for equipping mass-produced articles, in particular disposable articles, such as entry tickets or tokens for billing systems in holiday clubs, amusement parks and the like, are relatively expensive, and would often make them too expensive.
Vor diesem Hintergrund ist es zum einen Aufgabe der vorliegenden Erfindung, eine manipulationssichere Abschirmung von Transponderetiketten zu schaffen, wobei das Hauptaugenmerk auf einem Manipulationsschutz vor der Erstbenutzung des Transponderetiketts liegt. Zum anderen ist es Aufgabe der vorliegenden Erfindung eine kostengünstig implementierbare Abschirmung von Transponderetiketten zu schaffen. Gemäß einem Aspekt der vorliegenden Erfindung wird die zugrundeliegende Aufgabe durch ein Transponderetikett nach Anspruch 1 gelöst.Against this background, it is an object of the present invention to provide a tamper-proof shielding of transponder labels, the main focus being on tamper protection before the first use of the transponder label. On the other hand, it is an object of the present invention to provide a shielding of transponder labels which can be implemented cost-effectively. According to one aspect of the present invention, the underlying object is achieved by a transponder label according to claim 1.
Vorteilhafte Ausführungsformen können gemäß einem der Ansprüche 2-21 gestaltet sein. Besonders bevorzugt sind dabei Ausführungsformen, welche einen Erstbenutzungsnachweis enthalten, d.h. Mittel welche irreversibel sichtbar oder auf andere Weise erkennbar machen, daß bereits ein Versuch unternommen wurde, die Abdeckung abzunehmen.Advantageous embodiments may be designed according to one of claims 2-21. Particularly preferred embodiments are those which contain a first-use proof, i. Means which are irreversibly visible or otherwise detectable, that an attempt has already been made to remove the cover.
Erfindungsgemäß ist ein Transponderetikett, welches grundsätzlich wie herkömmliche Transponderetiketten gestaltet und hergestellt sein kann, wobei der Ausdruck Transponderetikett gemäß obiger Begriffsbestimmung aufzufassen ist, mit einer vorzugsweise folienartig ausgeführten, abschirmenden Abdeckung versehen, welche vom restlichen Transponderetikett abnehmbar bzw. abziehbar ist. Die Abdeckung kann dabei je nach Anwendungsfall auf unterschiedlichste Weise gestaltet sein, muß jedoch mindestens eine, zumindest den Bereich der Antenne der Transponderanordnung überwiegend überdeckende, leitende Schicht aufweisen. Vorteilhaft ist die Verwendung von Metallfolien, Metall-Kunststoff-Verbundfolien, mit einer Leitpaste bedrucktem Papier uvm.According to the invention, a transponder label, which basically can be designed and manufactured like conventional transponder labels, the term transponder label being understood in accordance with the above definition, is provided with a preferably foil-like, shielding cover which can be removed or removed from the remaining transponder label. Depending on the application, the cover can be designed in many different ways, but must have at least one conductive layer that covers at least the area of the antenna of the transponder arrangement. The use of metal foils, metal-plastic composite foils, printed paper with a conductive paste and much more is advantageous.
Darunter, daß die Abdeckung einseitig ausgebildet und am Transponderetikett gehaltert ist, ist zu verstehen, daß die Abdeckung entgegen dem Stand der Technik nicht als Hülle ausgebildet ist, in welche das Etikett lediglich eingeschoben ist, sondern daß ein Verbindung zwischen der Abdeckung und dem restlichen Etikett vorgesehen ist: Die Verbindung zwischen Abdeckung und restlichem Transponderetikett kann vorteilhafterweise mittels einer ganz- oder teilflächig vorgesehenen Klebstoffschicht erfolgen, um die hilfsmittelfreie Abnehmbarkeit bzw. Abziehbarkeit zu gewährleisten. Denkbar sind jedoch auch andere Formen der Verbindung, beispielsweise über Schweißpunkte, Schweißnähte im Randbereich uvm.Including that the cover is formed on one side and held on transponder label, it should be understood that the cover is formed contrary to the prior art not as a shell in which the label is merely inserted, but that a connection between the cover and the rest of the label The connection between the cover and the remaining transponder label can advantageously be effected by means of an adhesive layer provided on all or part of the surface in order to ensure the removability of the tool-free removal or peelability. Conceivable, however, are other forms of connection, for example via welds, welds in the edge area and much more.
Es können auch zwei einander gegenüberliegende einseitige Abdeckungen vorgesehen sein. Das Attribut einseitig ist dabei so zu verstehen, daß die Abdeckungen unabhängig voneinander am Transponderetikett gehaltert sind, die Transponderanordnung also dennoch zweiseitig abgeschirmt ist (und zwar mittels jeweils einer Abdeckung). Die Grundschicht kann vorteilhafterweise ein- oder mehrlagig ausgebildet sein, und beispielsweise aus Kunststoff, Pappe oder Verbundmaterial bestehen.It can also be provided two opposing one-sided covers. The attribute on one side is understood to mean that the covers are mounted independently of each other on the transponder label, so the transponder assembly is still shielded on both sides (by means of a respective cover). The base layer may advantageously be formed in one or more layers, and for example made of plastic, cardboard or composite material.
Die vorzugsweise vorgesehenen folienartige Abdeckungen besitzen den Vorteil, daß sie einfach und mit wenig Aufwand herstellbar sind, und sich gut für die Integrierung eines Erstbenutzungsnachweises eignen. Insbesondere Massenware läßt sich sehr viel leichter und kostengünstiger mit aufgeklebten Metallverbundfolien versehen, als sie stückweise in steife Hüllen einzuführen.The preferably provided film-like covers have the advantage that they can be produced easily and with little effort, and are well suited for the integration of a first-use certificate. In particular mass-produced can be much easier and cheaper provided with glued metal composite films, as they introduce piece by piece in rigid cases.
Neben sogenannten Voidfolienaufbauten, welche für sich betrachtet in vielfachen Ausführungen bekannt sind, eignen sich unterschiedlichste Maßnahmen, beispielsweise Anstanzungen in der Abdeckung, welche es unmöglich machen, diese in einem Stück abzuziehen, oder photographisch mit einer gewissen Verzögerung selbstentwickelnde Elemente unter der in diesem Falle opak auszuführenden Abdeckung. Derartige Elemente sind beim ersten Abziehen der Abdeckung erst nach gewisser Zeit sichtbar, war dagegen die Abdeckung bereits teilweise entfernt, so sind sie sofort nach nochmaligem Abziehen der Abdeckung sichtbar. Analog sind natürlich auch Elemente denkbar, welche einen bei Belichtung langsam sichtbar werdenden Farbumschlag zeigen.In addition to so-called Voidfolienaufbauten, which in itself are known in many versions, a variety of measures, such as stamping in the cover, which make it impossible to deduct them in one piece, or photographically with some delay self-developing elements under the in this case opaque to be performed cover. Such elements are only visible after a certain period of time when the cover is first removed, but if the cover has already been partially removed, they are immediately visible after the cover has been removed again. Analogously, of course, elements are conceivable which show a slowly becoming visible upon exposure color change.
Besonders bevorzugt ist ein Folienaufbau, welcher bei Biegebelastung irreversibel farbverändernde Bestandteile aufweist. Ein entsprechender Aufbau kann hergestellt werden, wie in WO 91 /19649 AI beschrieben.Particularly preferred is a film structure which has irreversibly color-changing components at bending load. A corresponding structure can be produced, as described in WO 91/19649 AI.
Als, vorzugsweise in die Abdeckung integrierte, Echtheitsmerkmale kommen neben den bereits oben aufgeführten Voidfolienaufbauten, welche für die meisten Fälscher schwer herstellbar sein dürften, auch andere an sich bekannte Echtheitsmerkmale, wie etwa Mikroschrift, holographische Elemente, Reliefdruck uvm. in betracht.As, preferably integrated in the cover, authenticity features come in addition to the above-mentioned Voidfolienaufbauten, which should be difficult to produce for most counterfeiters, other known per se authenticity features, such as micro-writing, holographic elements, relief printing and more. in consideration.
Mittel zum zeitweisen Wiederanbringen der Abdeckung durch den rechtmäßigen Nutzer können beispielsweise als Knicklaschen, Steckschlitze, Haftbeschichtung uvm. ausgeführt sein. Grundsätzlich kann jede im Rahmen der vorliegenden Anmeldung beschriebene bzw. angedeutete Variante der Erfindung besonders vorteilhaft sein, je nach wirtschaftlichen und technischen Bedingungen im Einzelfall. Soweit nichts gegenteiliges dargelegt ist, bzw. soweit grundsätzlich technisch realisierbar, sind einzelne Merkmale der beschriebenen Ausführungsformen austauschbar oder miteinander kombinierbar.Means for temporarily reinstalling the cover by the rightful user, for example, as buckling tabs, slots, adhesive coating uvm. be executed. In principle, any variant of the invention described or indicated in the context of the present application may be particularly advantageous, depending on the economic and technical conditions in the individual case. Unless otherwise stated, or as far as technically feasible, individual features of the described embodiments are interchangeable or combinable.
Nachfolgend werden anhand der zugehörigen Zeichnungen Beispiele bevorzugter Ausführungsformen der vorliegenden Erfindung näher erläutert. Die Zeichnungen sind dabei rein schematische und nicht maßstäbliche Darstellungen. Einander entsprechende Elemente sind in den einzelnen Figuren jeweils, soweit sinnvoll, mit denselben Bezugszeichen versehen.Hereinafter, examples of preferred embodiments of the present invention will be explained in detail with reference to the accompanying drawings. The drawings are purely schematic and not to scale. Corresponding elements are provided in the individual figures, where appropriate, with the same reference numerals.
Fig. 1 a-d zeigen dabei ein erfindungsgemäßes Transponderetikett vor, während und nach Abziehen der abschirmenden Abdeckung.1 a-d show a transponder label according to the invention before, during and after removal of the shielding cover.
Fig. 2-3 zeigen ähnlich Fig. 1 a-d gestaltete Transponderetiketten während desFIGS. 2-3 show transponder labels designed similar to FIGS
Abziehens der abschirmenden Abdeckung, wobei zwei alternative Formen von Anfaßhilfen vorgesehen sind.Peel off the shielding cover, wherein two alternative forms of Anfaßhilfen are provided.
Fig. 1 a zeigt das kartenartig gestaltete Transponderetikett mit einer abschirmenden Abdeckung 1 aus einer Kunststoff-Metall-Verbundfolie mit Voideffekt. Als Metallanteile kommen unter anderem Silberschichten, Aluminiumfolien oder weichmagnetische Legierungen in betracht. Herstellbar sind derartige Folien u.a. durch Zusammenlaminieren von Metall- und Kunststoffolien, durch Bedrucken von Kunststoffolien mittels Leitpasten oder durch galvanische Abscheidung von Eisen- oder Ferritpartikeln.Fig. 1a shows the card-like designed transponder label with a shielding cover 1 made of a plastic-metal composite film with void effect. Among others, silver layers, aluminum foils or soft magnetic alloys are considered as metal components. Produceable such films u.a. by laminating together metal and plastic foils, by printing on plastic foils by means of conductive pastes or by galvanic deposition of iron or ferrite particles.
Die leitenden Bestandteile in der Abdeckung sorgen für eine Abschirmung der Transponderanordnung, welche unbefugtes bzw. unbeabsichtigets Auslesen, Beschreiben oder Löschen des Transponderchips 8 unmöglich macht oder stark erschwert. Daneben sind auch Anwendungen denkbar, bei welchen ein Auslesen und/ oder Beschreiben des Transponderchips 8 mit Geräten hoher Sende- bzw. Empfangsleistung aus geringer Distanz durch die entsprechend gestaltete Abdeckung 1 hindurch möglich ist. Die Abdeckung 1 ist mit einem Aufdruck 2a, 2b, 2c versehen, welcher einen graphischen Hinweis 2a auf eine Anfaßlasche, einen Barcode 2b und einen Texthinweis 2c enthält. Der Texthinweis 2c erläutert die Void-Funktion, d.h. die Funktion des Erstbenutzungsnachweises der Abdeckung 1.The conductive components in the cover provide for a shielding of the transponder assembly, which makes unauthorized or unintentional reading out, writing or erasing the transponder chip 8 impossible or very difficult. In addition, applications are conceivable in which a reading and / or writing the transponder chip 8 with devices high transmission or reception power from a small distance through the correspondingly shaped cover 1 is possible therethrough. The cover 1 is provided with an imprint 2 a, 2 b, 2 c, which contains a graphic indication 2 a on a grip tab, a bar code 2 b and a text hint 2 c. The text hint 2c explains the void function, ie the function of the first-use verification of the cover 1.
Die Abdeckung 1 ist außer im Bereich der Anfaßlasche 3 unterseitig mit Klebstoff 4 beschichtet, was in Fig. I c durch eine Kreuzschraffur angedeutet ist. Vorliegend ist eine unterseitig klebstoffreie Ecke der Abdeckung 1 als Anfaßlasche 3 ausgebildet. Anstelle einer Aussparung in der Klebstoffschicht 4 kann diese im Bereich der Anfaßlasche 3 auch mittels eines die Klebkraft aufhebenden bzw. stark vermindernden sogenannten " Klebstoff killers" behandelt sein.The cover 1 is coated on the underside with adhesive 4 except in the region of the gripping tab 3, which is indicated in FIG. 1 c by cross-hatching. In the present case, a bottom side adhesive-free corner of the cover 1 is designed as a gripping tab 3. Instead of a recess in the adhesive layer 4, it can also be treated in the region of the gripping tab 3 by means of a so-called "adhesive killer" which removes the adhesive force or greatly reduces it.
Eine alternative Ausführungsform der Anfaßlasche 3, welche als über die GrundschichtAn alternative embodiment of the grip tab 3, which as over the base layer
5 hinausragender Teil der Abdeckung 1 gestaltet ist, ist in Fig. 2 dargestellt.5 protruding part of the cover 1 is designed, is shown in Fig. 2.
In Fig. 3 ist eine weitere alternative Anfaßhilfe abgebildet, welche in einer AussparungIn Fig. 3, another alternative Anfaßhilfe is shown, which in a recess
6 in der Grundschicht 5 besteht. In diesem Bereich ist die Klebstoffschicht 4 der Abdeckung 1 ausgespart oder neutralisiert.6 in the base layer 5 consists. In this area, the adhesive layer 4 of the cover 1 is recessed or neutralized.
Die Transponderanordnung weist eine Antenne 7 und einen Transponderchip 8 auf. Sie ist mit einer transparenten Kunststoff-Schutzschicht überzogen. Selbstverständlich sind auch opake Schutzschichten möglich. Die Schutzschicht verhindert, daß beim Abziehen der Abdeckung 3 Teile der Transponderanordnung an der Klebstoffschicht 4 hängenbleiben. Die Schutzschicht kann aufgeklebt, auflaminiert oder mit der Grundschicht 5 verschweißt sein. Ebenso kann die Transponderanordnung in eine Kunststoffgrundschicht 5 eingegossen sein, so daß letztere die Funktionen von Grundschicht 5 und Schutzschicht übernimmt.The transponder arrangement has an antenna 7 and a transponder chip 8. It is covered with a transparent plastic protective layer. Of course, opaque protective layers are possible. The protective layer prevents 3 parts of the transponder assembly stuck to the adhesive layer 4 when removing the cover. The protective layer can be glued, laminated or welded to the base layer 5. Likewise, the transponder assembly may be cast in a plastic base layer 5, so that the latter takes over the functions of base layer 5 and protective layer.
Wie in Fig. 1 d angedeutet, kann auch die Schutzschicht und/oder die Grundschicht 5 einen Aufdruck 1 2 tragen.As indicated in FIG. 1 d, the protective layer and / or the base layer 5 can also carry an imprint 1 2.
Beim Abziehen der Abdeckung 1 wird ein Voideffekt ausgelöst, d.h. ein Schriftzug 9 wird sichtbar, wie in Fig. 1 c angedeutet. Hierfür kann ein herkömmlicher Voidfolienaufbau in die Abdeckung 1 integriert werden. Der Voideffekt ist irreversibel, d.h. der Schriftzug 9 läßt sich nicht mehr unsichtbar machen. Das Abziehen der Abdeckung 1 kann somit als Nachweis für die Erstbenutzung dienen. When removing the cover 1, a void effect is triggered, ie a lettering 9 is visible, as indicated in Fig. 1 c. For this purpose, a conventional Voidfolienaufbau be integrated into the cover 1. The void effect is irreversible, ie the lettering 9 can no longer be made invisible. The removal of the cover 1 can thus serve as proof of the first use.
