Description

Emballage anti-fraude pour carte à circuit intégré comportant des moyens de communication à distance Anti-fraud packaging for an integrated circuit card comprising means of remote communication
L'invention concerne un emballage anti-fraude pour une carte à circuit intégré comportant des moyens de communication à distance par voie électromagnétique.The invention relates to anti-fraud packaging for an integrated circuit card comprising means of remote communication by electromagnetic means.
L'invention se rapporte particulièrement à un emballage pour une carte à circuit intégré du type sans contact, par exemple du type dans lequel un corps de carte en forme de plaque porte un circuit intégré et une antenne par laquelle le circuit intégré est apte à communiquer à distance avec un terminal de réception, et du type dans lequel l'antenne, qui s'étend dans le plan du corps de carte, est réalisée sous la forme d'une spire ou d'un enroulement, sur plusieurs spires, d'un chemin conducteur.The invention relates particularly to a package for an integrated circuit card of the contactless type, for example of the type in which a card-shaped card body carries an integrated circuit and an antenna by which the integrated circuit is able to communicate remotely with a reception terminal, and of the type in which the antenna, which extends in the plane of the card body, is produced in the form of a turn or of a winding, over several turns, of a conductive path.
Dans une application particulièrement courante, les cartes à circuit intégré, aussi appelées cartes à puce, sont utilisées en tant que moyen de paiement d'un service. A chaque utilisation du service correspondant, au moins une unité de valeur est décrémentée dans un stock initial d'unités de valeur chargé dans la mémoire de la carte à puce. De telles applications se retrouvent par exemple dans les cartes téléphoniques et dans les cartes de photocopieur.In a particularly common application, integrated circuit cards, also called smart cards, are used as a means of payment for a service. Each time the corresponding service is used, at least one value unit is decremented in an initial stock of value units loaded into the memory of the smart card. Such applications are found for example in telephone cards and in photocopier cards.
Aussi, les utilisateurs achètent une carte qui est initialement munie en mémoire d'un nombre donné d'unités de valeur correspondant au crédit maximal.Also, users buy a card which is initially provided in memory with a given number of value units corresponding to the maximum credit.
Dans la plupart des applications dans lesquelles la carte à circuit intégré est utilisée comme moyen de paiement, les cartes utilisées sont de type carte à contact dans lesquelles la carte comporte des pistes conductrices qui sont raccordées au module électronique ou circuit intégré, et qui sont destinées à permettre une liaison électrique entre la carte et le terminal de réception.In most applications in which the integrated circuit card is used as a means of payment, the cards used are of the contact card type in which the card comprises conductive tracks which are connected to the electronic module or integrated circuit, and which are intended to allow an electrical connection between the card and the receiving terminal.
Dans ce cas, il est assez facile de garantir à l'utilisateur qui achète une carte supposée comporter le nombre maximal d'unités de valeur, tout simplement en entourant la carte d'une enveloppe scellée, par exemple sous la forme d'un emballage "cellophane", c'est-à-dire en matériau plastique. L'absence d'altération de l'emballage atteste de la présence d'un nombre maximal d'unités. Une telle solution n'est toutefois pas satisfaisante lorsqu'il s'agit d'une carte sans contact avec laquelle les échanges d'informations s'effectuent à distance, par exemple par ondes électromagnétiques. En effet, cet échange d'information peut alors se faire au travers de l'enveloppe de cellophane, laquelle ne peut donc plus faire office de garantie de la non utilisation préalable de la carte.In this case, it is quite easy to guarantee to the user who buys a card supposed to contain the maximum number of value units, simply by surrounding the card with a sealed envelope, for example in the form of a package. "cellophane", that is to say in plastic material. The absence of tampering with the packaging attests to the presence of a maximum number of units. However, such a solution is not satisfactory when it is a contactless card with which information is exchanged remotely, for example by electromagnetic waves. Indeed, this exchange of information can then be done through the cellophane envelope, which can therefore no longer act as a guarantee of the prior non-use of the card.
L'invention a donc pour but de proposer une solution au problème ci-dessus.The object of the invention is therefore to propose a solution to the above problem.
A cet effet, l'invention propose de disposer des moyens anti-fraude dans l'emballage d'une carte à circuit intégré, ou carte à puce, permettant d'empêcher toute utilisation frauduleuse de la carte avant une première utilisation de celle- ci par un utilisateur autorisé.To this end, the invention proposes to have anti-fraud means in the packaging of an integrated circuit card, or chip card, making it possible to prevent any fraudulent use of the card before it is used for the first time. by an authorized user.
Plus précisément, l'invention propose un emballage anti-fraude contenant une carte à circuit intégré comportant des moyens de communication à distance par voie électromagnétique, du type comportant une enveloppe autour de la carte. Il est caractérisé en ce qu'il comporte au moins une feuille barrière en matériau conducteur qui est agencée en regard d'une face de la carte et qui s'étend sensiblement en regard des moyens de communication . Selon d'autres caractéristiques de l'invention :More specifically, the invention proposes an anti-fraud packaging containing an integrated circuit card comprising means of remote communication by electromagnetic means, of the type comprising an envelope around the card. It is characterized in that it comprises at least one barrier sheet of conductive material which is arranged facing one face of the card and which extends substantially opposite the means of communication.

Il est caractérisé en ce que l'enveloppe comporte au moins une feuille barrière en matériau conducteur.The invention also relates to anti-fraud packaging for an integrated circuit card comprising means of remote communication by electromagnetic means, of the type comprising an envelope around the card. It is characterized in that the envelope comprises at least one barrier sheet of conductive material.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels : - la figure 1 est une vue schématique à plat d'une carte à circuit intégré comportant une antenne de communication à distance par voie électromagnétique ;Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which: - Figure 1 is a schematic flat view of an integrated circuit card comprising a remote communication antenna by electromagnetic means;
- la figure 2 est une vue similaire à celle de la figure 1 illustrant la carte à circuit intégré une fois emballée dans son emballage conforme aux enseignements de l'invention ;- Figure 2 is a view similar to that of Figure 1 illustrating the integrated circuit card once packed in its packaging according to the teachings of the invention;
- la figure 3 illustre un chapelet de cartes emballées conformément aux enseignements de l'invention ; et- Figure 3 illustrates a string of cards packed in accordance with the teachings of the invention; and
- les figures 4, 5 et 6 sont des vues schématiques en coupe selon la ligne 5-5 de la figure 3 illustrant trois modes de réalisation de l'invention .- Figures 4, 5 and 6 are schematic sectional views along line 5-5 of Figure 3 illustrating three embodiments of the invention.
On a illustré sur la figure 1 une carte à circuit intégré 10 de type connu en soi. La carte 10 comporte essentiellement un corps de carte 12, réalisé par exemple en matière plastique au format standardisé d'une carte de crédit. La carte 10 comporte un microcircuit électronique 14 agencé à l'intérieur du corps de carte 12, ainsi que des moyens de communication 16 qui permettent au microcircuit 14 de communiquer à distance avec un circuit de lecture/écriture approprié (non représenté) appartenant à un lecteur de carte.Illustrated in Figure 1 an integrated circuit card 10 of a type known per se. The card 10 essentially comprises a card body 12, made for example of plastic material in the standardized format of a credit card. The card 10 comprises an electronic microcircuit 14 arranged inside the card body 12, as well as communication means 16 which allow the microcircuit 14 to communicate remotely with an appropriate read / write circuit (not shown) belonging to a card reader.
En l'occurrence, les moyens de communication sont réalisés sous la forme d'une antenne 16 elle-même réalisée par l'enroulement d'un conducteur 18 selon des spires concentriques coplanaires, contenues dans le plan de la carte 1 0.In this case, the means of communication are produced in the form of an antenna 16 itself produced by the winding of a conductor 18 according to concentric coplanar turns, contained in the plane of the card 1 0.
De manière connue, l'antenne 16 peut être réalisée à l'aide d'un fil métallique enroulé ou elle peut être réalisée par dépôt d'une encre conductrice.In known manner, the antenna 16 can be produced using a coiled metal wire or it can be produced by depositing a conductive ink.
Cette antenne 16 est donc capable de transformer un champ électromagnétique en un courant électrique, et vice versa, de manière à permettre l'interrogation à distance du microcircuit 14 et permettre éventuellement la modification du contenu d'une mémoire du microcircuit 14.This antenna 16 is therefore capable of transforming an electromagnetic field into an electric current, and vice versa, so as to allow remote interrogation of the microcircuit 14 and possibly allow the modification of the content of a memory of microcircuit 14.
Bien entendu, dans certaines applications, la carte à circuit intégré 1 0 peut comporter, en plus, des moyens de communication à contact permettant un échange des informations entre le microcircuit 14 et le lecteur de carte par l'intermédiaire de pistes de contact agencées sur la carte et reliées au microcircuit 14.Of course, in certain applications, the integrated circuit card 1 0 may further comprise contact communication means allowing an exchange of information between the microcircuit 14 and the card reader by means of contact tracks arranged on the card and connected to the microcircuit 14.
Il est connu d'emballer la carte 10 dans un emballage du type de celui illustré à la figure 2 comportant une enveloppe 20 formée d'un film en matériau plastique qui enveloppe complètement la carte 10 et qui est scellée sur ses bords 22. Suivant les cas, les bords scellés 22 peuvent être plus ou moins proches des bords de la carte 10. Conformément aux enseignements de l'invention, l'emballage de la carte 10 qui est illustré à la figure 2 comporte par ailleurs une feuille en matériau conducteur 24 qui est disposée contre l'une des faces de la carte, en regard de l'antenne 16, de manière à inhiber l'antenne 16 ou perturber les signaux entre le lecteur et la carte, c'est-à-dire de manière à rendre cette dernière inefficace, empêchant ainsi toute communication à distance entre le microcircuit 14 et un éventuel dispositif de lecture ou d'écriture.It is known to package the card 10 in a package of the type illustrated in FIG. 2 comprising an envelope 20 formed from a film of plastic material which completely envelops the card 10 and which is sealed on its edges 22. According to the In this case, the sealed edges 22 can be more or less close to the edges of the card 10. In accordance with the teachings of the invention, the packaging of the card 10 which is illustrated in FIG. 2 also includes a sheet of conductive material 24 which is arranged against one of the faces of the card, facing the antenna 16, so as to inhibit the antenna 16 or disturb the signals between the reader and the card, that is to say so as to render the latter ineffective, thus preventing any remote communication between the microcircuit 14 and a possible reading or writing device.
En effet, la feuille 24 en matériau conducteur forme une barrière électromagnétique qui empêche l'antenne 16 de remplir son rôle.Indeed, the sheet 24 of conductive material forms an electromagnetic barrier which prevents the antenna 16 from fulfilling its role.
On a illustré schématiquement sur les figures 4 à 6 plusieurs modes de réalisation qui permettent de réaliser de manière simple et économique un emballage pour une carte à circuit intégré 10 conformément aux enseignements de l'invention. Dans les exemples illustrés, l'enveloppe 20 est constituée d'une feuille inférieure 26 et d'une feuille supérieure 28 entre lesquelles la carte 10 est destinée à être interposée. Dans l'exemple qui est illustré schématiquement à la figure 4, la feuille barrière 24 est réalisée sous la forme d'une feuille en matériau conducteur distincte de l'enveloppe 20. La feuille 24 s'étend en regard de l'une des faces de la carte 10, et elle se trouve donc intercalée entre l'une des feuilles de l'enveloppe 20 et la carte 10. La feuille barrière 24 est donc introduite dans l'enveloppe en même temps que la carte 10.Several embodiments have been shown diagrammatically in FIGS. 4 to 6 which make it possible to produce packaging for an integrated circuit card 10 in a simple and economical manner in accordance with the teachings of the invention. In the examples illustrated, the envelope 20 consists of a lower sheet 26 and an upper sheet 28 between which the card 10 is intended to be interposed. In the example which is illustrated diagrammatically in FIG. 4, the barrier sheet 24 is produced in the form of a sheet of conductive material distinct from the envelope 20. The sheet 24 extends opposite one of the faces of the card 10, and it is therefore interposed between one of the sheets of the envelope 20 and the card 10. The barrier sheet 24 is therefore introduced into the envelope at the same time as the card 10.
Dans l'exemple de la figure 5, la feuille barrière 24 est superposée au film plastique constituant l'enveloppe 20 de l'emballage. Cette feuille plastique peut par exemple être laminée sur l'une des faces de l'emballage, de préférence du côté intérieur de l'enveloppe, et elle peut aussi être collée par tout moyen approprié.In the example of FIG. 5, the barrier sheet 24 is superimposed on the plastic film constituting the envelope 20 of the packaging. This plastic sheet can for example be laminated on one of the sides of the packaging, preferably on the inside of the envelope, and it can also be glued by any suitable means.
Dans l'exemple de la figure 6, on peut voir que la feuille barrière 24 en matériau conducteur forme une partie de l'enveloppe 20 qui entoure la carte 10. Dans le cas illustré, la feuille supérieure 28 de l'enveloppe 20 est donc constituée d'une bande centrale formée par la feuille barrière 24 et de deux bandes latérales 32 en matériau plastique. Les bandes latérales 30 sont alors juxtaposées à la feuille barrière 24. Bien entendu , comme on peut le voir à la figure 3, l'emballage des cartes à circuit intégré 10 est généralement réalisé sous la forme d'un chapelet, c'est-à-dire que les feuilles formant l'enveloppe 20 des cartes sont continues, l'enveloppe de chaque carte étant individualisée par exemple par des lignes de prédécoupe 32 réalisées au niveau d'un bord scellé 22 transversal. Afin de garantir une parfaite inhibition de l'antenne 26, il est nécessaire de s'assurer que la feuille barrière 24 s'étend en regard de l'intégralité de l'étendue de l'antenne 26. Aussi, en fonction des tolérances de positionnement de la carte, et en fonction des différentes positions possibles de l'antenne 26, on prévoira une feuille barrière 24 de taille suffisante.In the example of FIG. 6, it can be seen that the barrier sheet 24 of conductive material forms part of the envelope 20 which surrounds the card 10. In the illustrated case, the upper sheet 28 of the envelope 20 is therefore consisting of a central strip formed by the barrier sheet 24 and two side strips 32 of plastic material. The lateral strips 30 are then juxtaposed with the barrier sheet 24. Of course, as can be seen in FIG. 3, the packaging of the integrated circuit cards 10 is generally produced in the form of a chain, that is to say that is to say that the sheets forming the envelope 20 of the cards are continuous, the envelope of each card being individualized for example by precut lines 32 produced at a sealed edge 22 transverse. In order to guarantee perfect inhibition of the antenna 26, it is necessary to ensure that the barrier sheet 24 extends opposite the entire extent of the antenna 26. Also, depending on the tolerances of positioning of the card, and according to the different possible positions of the antenna 26, a barrier sheet 24 of sufficient size will be provided.
Dans l'exemple de réalisation illustré sur les figures, l'emballage ne comporte qu'une feuille barrière 24 mais, dans certaines applications, il peut s'avérer nécessaire de prévoir deux feuilles 24 agencées chacune d'un côté de la carte 26 en regard l'une de l'autre.In the embodiment illustrated in the figures, the packaging comprises only one barrier sheet 24 but, in certain applications, it may prove necessary to provide two sheets 24 each arranged on one side of the card 26 in look at each other.
La feuille barrière 24 peut être réalisée en tout matériau conducteur et notamment à l'aide d'une feuille de matériau métallique tel que de l'aluminium. Toutefois, d'autres matériaux métalliques peuvent convenir et il est aussi possible d'utiliser un film polymère chargé en particules conductrices.The barrier sheet 24 can be made of any conductive material and in particular using a sheet of metallic material such as aluminum. However, other metallic materials may be suitable and it is also possible to use a polymer film loaded with conductive particles.
De même, il est possible de prévoir que l'intégralité de l'enveloppe 20 soit réalisée en matériau conducteur, ce qui dispense alors de prévoir une feuille barrière rapportée. Bien que l'invention ait été décrite en référence à une carte à puce, elle peut également s'appliquer à tout support à puce contenant une interface de communication électromagnétique, tel qu'une étiquette électronique, module sans contact auto-collant à antenne... Le mot carte à puce doit donc être entendu dans la présente invention au sens large de tout support à puce. Similarly, it is possible to provide that the entire envelope 20 is made of conductive material, which then dispenses with providing an added barrier sheet. Although the invention has been described with reference to a smart card, it can also be applied to any smart support containing an electromagnetic communication interface, such as an electronic label, self-adhesive contactless module with antenna. .. The word smart card must therefore be understood in the present invention in the broad sense of any smart medium.
