    Cover of an electronic payment terminal, corresponding electronic payment terminal.
    TECHNICAL AREA
    The field of the invention is that of ergonomics and more particularly the backlighting of electronic payment terminals, as well as that of the physical security of such terminals, in particular at the level of their cover.
    TECHNOLOGICAL BACKGROUND
    The backlighting functionality of a payment terminal allows certain areas of the terminal, such as the keyboard keys, the card insertion slot or the area dedicated to contactless payment, to be lit from inside the terminal, in order to be more visible to the user.
    The backlight also allows the implementation of visual indicators informing the user of the activation of a functionality, such as for example light points (fixed or flashing) during the activation of the contactless payment functionality.
    These backlit areas are therefore therefore areas which should not be covered by the cover of the terminal, which is necessarily opaque moreover to mask and protect the interior of the terminal, for obvious security reasons.
    Furthermore, the backlight of a payment terminal must be designed and implemented in such a way as to guarantee the security and physical integrity of the terminal against external physical attacks.
    Indeed, there are for example attacks called "overlay attacks" consisting in covering part of an electronic payment terminal with a plastron, wider than the authentic cover of the terminal, in order to hide fraudulent elements allowing access sensitive data passing through the terminal, or preventing the release of the inserted smart card (to recover it later) ...
    These attacks are in particular possible when there is a fault, however small, in the physical means of securing the terminal, for example places of weakness between two elements or two areas of the cover, such as potentially the backlit areas.
    Thus, for example, some electronic payment terminals have light guides making it possible to guide the light supplied by a light source inside the terminal (for example one or more LEDs) towards the area to be backlit, these light guides passing through hood openings (for the contactless card reader for example) and therefore constituting points of weakness and access to the interior of the electronic payment terminal, and therefore potentially attack points.
    A solution of the prior art to limit these weaknesses consists in reducing the dimensions of the light guides, or in limiting the backlit areas. On the other hand, a drawback of these solutions lies in a degradation of the ergonomics of the electronic payment terminal.
    There is therefore a need for a backlighting technique for an electronic payment terminal which is optimal in terms of ergonomics for the user, while not degrading the physical security of the terminal.
    There is also a need for such a backlighting technique to have a controlled cost and an easy technical implementation.
    ABSTRACT
    The invention provides a cover for an electronic payment terminal having at least one area to be backlit, the cover comprising at least one part comprising at least one lower layer and one upper layer assembled during the manufacture of said cover. In addition, the lower layer is opaque or semi-opaque and has at least one opening facing the at least one area to be backlit when the cover is assembled on the electronic payment terminal and the upper layer is translucent and covers the at least one opening in the bottom layer.
    Thus, the invention provides a new and inventive solution for the backlighting of an electronic payment terminal, while guaranteeing the physical integrity of the terminal.
    To do this, the invention provides, according to its various embodiments, that the cover of the electronic payment terminal consists, at least in part, of two superimposed layers during the manufacture of the cover, the lower layer being opaque (or semi-opaque) and having one or more openings facing the area or areas to be backlit and the upper layer being translucent and covering at least the opening of the lower layer.
    Thus, where the cover could have a brittleness through the opening (s) to allow the backlighting, a transparent upper layer is added thereto, allowing the light of the backlighting to pass through, while providing a physical barrier above of the opening (s) of the lower layer.
    These two layers being assembled during the manufacture of the cover, this assembly has no brittleness, including at the borders of the opening (s) of the lower layer, because these two layers cannot be separated without destroying the cover itself. Thus, no spy or fraudulent element can be inserted at the location of the opening of the lower layer, allowing optimal backlighting. Indeed, the area to be backlit can be very wide because it is entirely covered with the transparent upper layer of the cover.
    Furthermore, this solution makes it very difficult to attack with an "overlay", which would necessarily degrade the visual appearance, as well as the touch and the hardness, of these backlit areas covered with a layer of transparent material. Such an attack would then be detectable with the naked eye by a user, who would not use the electronic payment terminal and alerted its owner.
    Finally, the upper layer being translucent, and not completely transparent, it allows backlighting while preventing visibility when the electronic payment terminal is not backlit. Indeed, a translucent material masks, or makes blurred and without outline, the elements which it covers if it is not lit but lets pass the light when it is lit as in the case of a backlight of an electronic payment terminal.
    According to a particular aspect of the invention, the lower and upper layers are obtained by a technique for manufacturing the cover belonging to the group comprising:
    • overmolding of the upper layer on the lower layer;
    • bi-injection of the lower and upper layers.
    Thus, according to this particular embodiment of the invention, the manufacturing technique of the cover makes it possible to make the two layers inseparable, without however the materials mixing. The cover then has a surface cohesion, without opening and therefore flawless which could jeopardize the physical integrity of the electronic payment terminal, unlike some solutions of the prior art which provides for sticking, from the outside, a protective faceplate does not offer such security. Indeed, with these known solutions, it is possible to remove the plastron and replace it with a malicious plastron as in an overlay attack for example.
    In particular, the lower layer comprises Polycarbonate or Polycarbonate / Acrylonitrile Butadiene Styrene.
    Thus, according to this particular embodiment of the invention, the opaque lower layer is for example made of PC / ABS (Polycarbonate / Acrylonitrile Butadiene Styrene), mixture of PC and ABS. Indeed, this mixture makes it possible to obtain a combination of the high transformability of ABS and the mechanical properties, of impact and heat resistance of the PC, so as to reinforce as much as possible the quality of the cover of the electronic payment terminal.
    According to a particular characteristic of the upper layer comprises thermoplastic elastomer or thermoplastic polyurethane.
    Thus, according to this particular embodiment of the invention, the translucent upper layer is for example made of thermoplastic polyurethane, also called TPU, a material belonging to the group of thermoplastic elastomers (TPE or thermoplastic elastomer based on polyolefin). The performance of thermoplastic polyurethanes lies in the combination of their good physical and chemical properties.
    The invention also relates to an electronic payment terminal comprising a cover as described above.

    Figures la to lf show different views of an electronic payment terminal cover according to an embodiment of the invention;

    DETAILED DESCRIPTION OF THE INVENTION
    In all the figures in this document, identical elements and steps are designated by the same reference.
    The general principle of the invention consists in wrapping (by a known process of overmolding or bi-injection type) the covering of an electronic payment terminal with a translucent, or slightly transparent, thermoplastic material, in certain places of the covering, such as by example of the areas provided for the backlight. Thus, in this (s) area (s) to be backlit, the cover (conventionally opaque to make the interior of the electronic payment terminal invisible) is perforated, to pass the light from the backlight, and covered by the second layer of translucent material, which also lets in the light from the backlight.
    The final result gives a uniform external appearance, without holes, and therefore without fault for the physical integrity of the cover of the electronic payment terminal. Indeed, thanks to the surface cohesion between the materials, obtained at the time of manufacture of the cover of the electronic payment terminal, it is not possible to remove the translucent outer layer. Thus, this solution makes it possible to open the opaque part in specific areas, the translucent part covering these openings to avoid giving access to secure functions.
    In addition, as already indicated above, this solution offers a particular visual aspect (at the level of zones intended to be backlit) both opaque when the backlight is not activated and transparent when it is activated. This particular visual aspect is also accompanied by a specific feel, due to the translucent upper layer, and in particular to a specific hardness of the cover of the electronic payment terminal. These different elements differentiating this cover from a conventional cover therefore make it very difficult to attack with an "overlay", which would necessarily degrade the visual appearance and / or the feel and / or the hardness of these backlit areas. This solution therefore makes it possible to implement optimal backlighting zones in an electronic payment terminal, while guaranteeing the physical integrity of the latter.
    Figures la to lf show different views of a cover 10 of an electronic payment terminal, according to an embodiment of the invention.
    According to this embodiment, the cover 10 comprises a first lower layer 101, having at least two areas of openings allowing backlighting.
    A first opening area 1010 has for example four small openings corresponding to an indicator for activating the contactless payment functionality. Thus, when contactless payment is activated, four light points appear (for example from green LEDs activated continuously or alternately or one after the other).
    A second opening 1011, wider, corresponds to the backlighting of the logo of the contactless payment functionality, which lights up (often via a white LED) when the contactless payment is activated, in order to guide the user in positioning their contactless payment card.
    These two opening zones 1010 and 1011 correspond for example respectively to the two backlighting zones 20 and 21 visible in FIG. 3 (illustrating a front view of an electronic payment terminal).
    Conventionally, the cover of an electronic payment terminal is formed by an opaque material, in order to hide the interior of the electronic payment terminal. According to this embodiment, the lower layer 101 is therefore opaque and consists for example of PC / ABS (Polycarbonate / Acrylonitrile Butadiene Styrene), mixture of PC and ABS. Thus, this lower layer 101 has optimal qualities by combining those of ABS (high transformability for example) and those of PC (excellent mechanical properties, resistance to shock and heat for example).
    Furthermore, according to this embodiment, the cover 10 also comprises an upper layer 102, covering only part of the lower layer 101 (this is more visible in FIG. 1d for example) and in particular the part 101b of the lower layer. 101 showing the opening zones 1010 and 1011 intended for backlighting. In addition, this upper layer 102 is made of a translucent material (such as, for example, thermoplastic polyurethane, denoted TPU below) making it possible, on the one hand, to hide the elements which it covers when there is no backlight and secondly to let the light from the backlight pass.
    This is particularly illustrated in FIGS. 1a and 1b which show this upper layer 102 in transparency (as in the backlight configuration) over the lower layer 101, so as to cover, without masking it in an opaque manner.
    For example, as illustrated in FIG. 1d, the portion 101a of the lower layer 101 which is not covered by the upper layer 102 corresponds to a zone for receiving a screen (as illustrated more clearly in FIG. 3) , subsequently assembled on the cover of the electronic payment terminal, and not requiring to be covered by a layer of translucent material.
    It will be noted, in FIG. 1a, that the two layers 101 and 102 of the cover of the electronic payment terminal also have an opening 10b, making it possible for example to accommodate a keyboard (as illustrated more clearly in FIG. 3) which requires access to the printed circuit for electronic connections.
    Figures le and ld show the upper layer 102 masking part of the lower layer 101, as in a configuration where there is no backlighting, for example. It can thus be seen that the elements of the lower layer 101, and in particular the opening areas 1010 and 1011, are not visible under the upper layer 102, when they are not backlit. The translucent material chosen for the upper layer 102 therefore makes it possible to comply with the opacity criterion of the cover of the electronic payment terminal in a non-backlit configuration, while allowing the backlighting to be implemented in a secure manner.
    Figures le and lf show two exploded views in which the upper layer 102 is shown in gray, above the part 101b of the lower layer 101 on which it is assembled during the manufacture of the cover 10 of the terminal electronic payment. These views also make it possible to clearly see that the zones 1010 and 1011 provided for the backlighting are covered by the upper layer 102.
    Figure 2 illustrates a sectional view of part of the cover 10 of the electronic payment terminal, at the opening area 1011 provided for the backlighting of the contactless payment logo.
    Thus, it can be seen that this area 1011 corresponds well to an opening in the lower layer 101 and that the upper layer 102 covers this opening 1011, in order to protect access to the electronic payment terminal.
    For example, according to a first variant of the manufacture of the cover of the electronic payment terminal, the translucent layer 102 (for example made of TPU) covers the opaque layer 101 by means of a bi-injection process. This makes it possible to create cohesion, and not a mixture, between the materials so as to form only one part constituting the cover of the electronic payment terminal, while allowing optimal implementation of backlit areas. Indeed, the opening zones in the opaque layer of the cover being covered by the translucent layer, in a homogeneous and inviolable manner due to the manufacture itself, can be large if necessary and of any shape.
    According to a second variant of the manufacture of the cover of the electronic payment terminal, the translucent layer 102 covers the opaque layer 101 by means of an overmolding process, making it possible in this case to obtain protection of the lower opaque layer by a layer translucent upper. The same advantages as those obtained by the bi-injection process are obtained by this overmolding process.
    Therefore, any other manufacturing process having the same advantages can of course be used, such as for example a bi-injection or overmolding process using translucent ABS, silicone rubber (or Silicon rubber) or LSR (Liquid Silicon Rubber).
    Finally, Figure 3 shows a front view of an electronic payment terminal 1 according to this embodiment.
    As already indicated above, the cover 10 of the electronic payment terminal 1 has a first part 101a intended in particular for receiving the screen and a second part 101b intended for the keyboard (area 10b) as well as for the payment functionality without contact, illustrated more particularly by two backlighting zones 20 and 21. It is this part 101b which is covered by the translucent upper layer 102, in order to be able to implement this backlighting in an optimal and secure manner.
    According to other embodiments, the lower layer of the cover of the electronic payment terminal can be entirely covered with a translucent upper layer, in order to obtain the same effects as those described in relation to the embodiment described above. .
    Finally, other backlighting zones than those described above can be provided in the electronic payment terminal, and covered with the translucent upper layer, according to the same principles as the embodiment described above.
