PAYMENT DEVICE INTEGRATED INTO AN UNATTENDED ELECTRONIC PAYMENT TERMINAL

Description

Field of invention

[0001] The invention relates to the field of so-called unattended payment terminals, such as, for example, payment terminals for parking, for purchasing transport tickets or show tickets, ticket machines, drink or snack dispensers, fuel dispensers, etc., referred to in the remainder of the description, for ease of reading, as "unattended payment terminal" or "payment terminal". Prior art

[0002] Currently, such unattended payment terminals have at least two separate devices, arranged for example side by side or one above the other in the front of the payment terminal, or the parking kiosk, or even the vending machine... For example, as illustrated in the Figure 1, these two devices correspond on the one hand to a “remote keyboard” 1 (“Pinpad” in English), comprising a screen and a keyboard, and on the other hand to a contactless “target” 2 (“Contactless” in English), comprising a contactless antenna and an area displaying the contactless logo. These two devices are connected to each other in order to function as an electronic payment terminal. However, this configuration with two separate devices has certain drawbacks, particularly in terms of ergonomics for the user, size and security.

[0003] Indeed, in "monitored" electronic payment terminals, for example in shops, the area provided for approaching the card for a contactless payment is easily identifiable by the user because it is located on the electronic payment terminal itself (either on the screen or offset on top of the electronic payment terminal). On the other hand, when this area is offset from the rest of the electronic payment terminal, as in an unmonitored payment terminal, and in particular offset from the screen displaying the payment instructions (such as for example the instructions for inserting the card into the electronic payment terminal for contact payment or approaching the card for contactless payment), the user may not easily identify it and waste time looking for it before being able to make their payment.

[0004] Furthermore, integrating two separate devices into an unattended payment terminal is not optimal in terms of space requirements because it requires two separate locations within the terminal, as well as two openings in the front of the unattended payment terminal.

[0005] This configuration also has disadvantages in terms of securing the connection(s) essential for communication between the two devices to carry out transactions.

[0006] There is therefore a need for a solution to address the issues of integrating a payment device with a contactless payment module into an unattended payment terminal, while limiting the cost impacts on the manufacturing of unattended payment terminals and complying with the various security standards related to this integration and contactless payment.

[0007] US2017 / 357351 teaches a device combining a contactless communication module, a touchpad and a screen. WO2017 / 009816 discloses a device intended to form a contactless antenna near a payment terminal. Summary of the invention

[0008] The proposed technique makes it possible to solve at least some of the problems of the prior art, via an electronic payment device intended to be integrated into an unattended electronic payment terminal, the electronic payment device comprising at least one electronic card, a screen and a keyboard. According to the present technique, the electronic payment device comprises a contactless payment module comprising at least one contactless antenna arranged in a plane, called the antenna plane, raised by a first predetermined distance relative to the plane of the keyboard and raised by a second predetermined distance relative to the plane of the screen, the second predetermined distance being less than the first predetermined distance.

[0009] The proposed solution is based on a new and inventive approach to the integration of a contactless payment module, and more particularly the contactless antenna, into a payment device intended to be integrated into an unattended payment terminal.

[0010] To do this, the antenna is arranged in a plane raised relative to the plane of the metal keypad, the plane of the metal keypad being substantially identical to the metal plane of the front of the unattended payment terminal, when the payment device is integrated vertically into the unattended payment terminal. Thus, the antenna is away from the metal parts formed by the keypad and the front of the unattended electronic payment terminal (the metal being chosen for reasons of robustness and impact resistance), limiting the interference caused by these “front” metal parts.

[0011] Additionally, raising the antenna also allows it to be moved away from the "rear" metal part of the electronic payment device, thus limiting interference from any metal part located near the antenna.

[0012] Finally, the antenna is also raised above the plane of the screen, which is itself raised above the plane of the metal keypad, for visibility reasons. In this way, the elevation of the antenna above the screen brings it closer to the screen's protective glass, the distance of which is optimized compared to the front of the unattended payment terminal. The screen is therefore set back inside the casing, which reinforces the security of the screen against acts of vandalism.

[0013] The antenna, screen and keyboard planes are therefore superimposed and substantially parallel.

[0014] According to a particular aspect of the present technique, the contactless antenna is positioned above the screen and has a shape substantially identical to the shape of the screen and the contactless antenna has dimensions greater than those of the screen.

[0015] Thus, the antenna is positioned in the area above the screen and is not only raised above the plane of the screen but also larger than the screen, ensuring sufficient distance from the screen in all directions (around and above the screen) so as to limit mutual interference between the antenna and the screen. For example, the antenna is folded and shaped so as to reproduce the rectangular shape of the screen, with dimensions larger than those of the screen and with a descending part, along one side of the screen, for its connection to the electronic board.

[0016] According to a particular feature, the contactless antenna is positioned around an antenna support inside which the screen is embedded.

[0017] Thus, the elevation of the antenna relative to the screen is ensured by an antenna support, around which the antenna is positioned and inside which the screen is itself positioned. To achieve this, the dimensions of the antenna must therefore be greater than those of the screen, because they are greater than those of the support in which the screen is embedded. This technical solution ensures its distance from the screen, in all directions, while providing support for the antenna.

[0018] For example, this support corresponds to a plastic case of parallelepiped shape (more precisely in the form of a pad) having a window on one of its faces and an opening on the opposite face for the insertion of the screen (and the seal around the screen). The antenna matches the shape of the support at the level of the upper part (close to the window) of the other four faces of the pad. When the payment device is assembled, the window of the case forming the antenna support is thus in a plane parallel to the plane of the screen and the plane of the keyboard, the four faces around which the antenna is wound being perpendicular to these screen and keyboard planes. For example, the contactless antenna is arranged perpendicular to the antenna plane so as not to obstruct the viewing of the screen.

[0019] Thus, since the antenna is arranged "around" the screen, although in a plane raised relative to that of the screen, it is preferable to arrange it vertically, i.e. perpendicular to the plane of the screen, so as to limit its footprint and not encroach on the screen. This vertical positioning thus makes it possible not to reduce the size of the screen, which is also subject to compactness constraints to be respected for the integration of the payment device in an unattended payment terminal.

[0020] This vertical positioning also makes it easy to adapt the antenna around a plastic support in the form of a pad, for example in a notch provided on the “vertical” faces of the pad relative to the plane of the keyboard.

[0021] According to a particular aspect of the proposed technique, the electronic payment device is integrated into a housing comprising a front part and a rear part, the front part being made from a non-conductive material meeting predetermined mechanical robustness constraints.

[0022] Thus, interference due to metal parts near the antenna is greatly limited by the use of a non-conductive material for the front part of the payment device casing, and by raising the antenna to keep it away from the front metal part corresponding to the front of the unmonitored payment terminal and the rear metal part of the casing. However, the choice of such a non-conductive material for the front part is also governed by mechanical constraints of robustness, the front part being directly exposed to the risks of vandalism.

[0023] For example, the non-conductive material is glass-fiber reinforced polycarbonate. The choice of this material results from a compromise between resistance to vandalism attacks, such as attacks with sharp objects (knives, scissors, etc.) or flames, and the precision of production of the parts concerned, and in particular the front part of the electronic payment device housing, including a rim on its periphery.

[0024] According to a particular characteristic, at least part of the contactless antenna connecting it to the electronic card of the electronic payment device is inserted into a sealing enclosure made of non-conductive material.

[0025] According to this embodiment, a solution is proposed to overcome possible water infiltration problems that may arise due to the exposure of the antenna on the front face. To ensure sealing at the point where the antenna enters the sealed area (electronic card), a plastic overmolding is thus provided at the base of the antenna.

[0026] According to a particular aspect, the antenna support comprises a window on a face opposite the face formed by the screen embedded in the antenna support, and the volume between the window and the screen is less than a predetermined volume, and a seal is positioned around the screen inside the antenna support to protect against condensation phenomena.

[0027] According to this embodiment, a solution is proposed to overcome possible condensation problems by reducing the volume of air between the lower part of the glass and the upper part of the screen and by providing a seal around the screen. This volume of air is specific to the display area.

[0028] Furthermore, the midpoint of the contactless antenna is connected to the ground of the electronic board.

[0029] This feature allows ESD ("ElectroStatic Discharge") considerations to be taken into account in the configuration where the front part of the payment device casing is made of non-conductive material. Indeed, in this case, the antenna represents the first metal part through which the user discharges "electrostatically" by placing his payment card (unlike configurations in which it is the smart card reader that provides an ESD discharge zone). By connecting the midpoint of the antenna to the ground of the electronic card, the contactless component is therefore prevented from being damaged by electrostatic discharges, by flowing the ESD discharge into the ground of the payment device.

[0030] According to a particular characteristic, the electronic payment device further comprises at least one means for detecting the placement of a spy device on the keyboard among: an external backlighting device arranged above the keyboard keys; a cutout in the lower part of the peripheral edge of the front part of the electronic payment device housing; at least one embossing near the keyboard keys.

[0031] Thus, at least one of these means makes it possible to detect, visually (for example by a person in charge of the maintenance and occasional monitoring of the unmonitored payment terminal) the installation of a spy keyboard, or fake keyboard or even "skimmer" in English (a technique making it possible to recover the confidential code on which it is entered, without the knowledge of the user who thinks he is entering his code directly on the keyboard of the payment terminal) on the keyboard of the payment device.

[0032] Indeed, the external backlighting above the keys is modified when a fake keyboard is glued over the authentic keyboard of the payment device, and this modification is detectable by an informed person whose role is to detect a hacking attempt. Similarly, the less prominent edge at the bottom of the keyboard, which also facilitates access to the keyboard keys, is no longer visible if a fake keyboard is glued. Finally, one or more embossments provided between certain keys is (are) necessarily covered by a fake keyboard and the absence of this (these) embossment(s) is easily detectable by an informed person whose role is to detect a hacking attempt.

Detailed description of the proposed technique

[0034] The problem faced by the inventors of the present application lies in the integration, within a single electronic payment device itself integrated into an unattended payment terminal, of the contactless payment functionality. A large number of constraints then appeared, linked on the one hand to the context of use of these unattended payment terminals and on the other hand to the operational and security requirements of the contactless payment functionality.

[0035] Thus, the inventors sought to solve the technical problem of integrating a contactless solution into a metal support (a material essential for resisting bad weather and respecting the mechanical constraints essential for resisting vandalism to which unsupervised payment terminals are exposed) while remaining compatible with contactless payment standards relating to the efficiency of the contactless antenna, with optimal ergonomics for the user, and with the security standards relating to electronic payment terminals. Other more specific constraints also appeared during the development of each solution and are described below in more detail.

[0036] The general principle of the invention therefore consists of proposing an electronic payment device in a single box 10 (an example of which is illustrated by the Figures 2a And 2b, representing respectively a front view and a rear view), presenting all the required functionalities including contactless payment and intended to be integrated into an unattended payment terminal.

[0037] To do this, the inventors first sought to move the contactless antenna (of the contactless payment module) as far away as possible from the metal parts present in the electronic payment device itself as well as in the unmonitored payment terminal in which it is integrated. The contactless antenna must therefore be moved away on the one hand from the metal keypad and the rear part of the electronic payment device housing and on the other hand from the front of the payment terminal.

[0038] According to the general principle, schematized on the Figure 3a , the plane of the contactless antenna P- CLESS is therefore raised relative to the plane of the keyboard P - Kfrom the payment device, a first distance d1 chosen so as to limit interference between the metal keypad and the contactless antenna. For example, this distance d1 is between nine and twenty millimeters, preferably close to nine millimeters, a distance resulting from a compromise between optimal performance of the antenna and the compactness of the payment device at the level of the antenna and the screen.

[0039] This elevation, however, poses problems linked to the choice of location of the antenna within the payment device.

[0040] Indeed, this elevation supposes a difference in height between the keyboard and the contactless antenna, these two elements must however be accessible to the user, to enter a code or to place a contactless payment card near the antenna. Thus, this elevation causes a significant increase in the thickness of the payment device, due to this difference in height between the keyboard and the contactless antenna.

[0041] The inventors therefore sought to position the antenna in such a way as to minimize the impact of this elevation. Thus, they first tested positioning the antenna around the payment device, in a rim surrounding it, also providing a transverse rim in the middle of the payment device to position the contactless logo (in order to comply with the standards governing contactless payment). This configuration allows the contactless antenna to be moved away from the keypad, as well as from the front of the unattended payment terminal, because the antenna is positioned in a plane raised relative to the plane of the keypad (substantially identical to the plane of the front of the payment terminal). However, this configuration has at least the following drawbacks: the edge surrounding the payment device significantly impairs accessibility to the keyboard keys, mainly those located at the bottom of the keyboard; this edge also significantly impairs visibility / readability on the screen; when the payment device is integrated horizontally or inclined relative to the front of the payment terminal (and not vertically, in a plane substantially identical to that of the front), the recesses created at the level of the screen and the keyboard by the peripheral edges and the middle edge supporting the contactless logo form a kind of “basins” in which water (rainwater for example) stagnates and is likely to damage the product, as well as limit or even prevent the readability of the screen in particular.

[0042] The inventors therefore sought to resolve these problems by positioning the antenna elsewhere in the payment device and more particularly by choosing a configuration "around" the screen. It should be noted that this choice goes against current architectural developments in fixed or portable electronic payment terminals because this antenna configuration around the screen is used less and less today for reasons of compactness and reciprocal interference between the contactless antenna and the screen, making it difficult to apply new contactless payment standards.

[0043] Within the framework of the present technique, however, the inventors have succeeded in finding a solution to these problems of reciprocal interference between the contactless antenna and the screen, on the one hand by raising the antenna by a second distance d2 relative to the screen (itself slightly raised relative to the keyboard for better visibility) and on the other hand by laterally moving the antenna away from the screen.

[0044] This configuration is shown diagrammatically on the Figure 3b , on which the three superimposed keyboard planes are visible PK, screen P-Dis and contactless antenna P-CLESS.

[0045] Furthermore, according to an embodiment of the present technique, the contactless antenna has a shape substantially identical to that of the screen, i.e. most generally a rectangle, with dimensions greater than those of the screen, so as to increase its “lateral” distance from the screen. Figure 3cillustrates part of certain elements of a payment device according to an embodiment of the present technique, and in particular the contactless antenna 11 of rectangular shape, raised by a distance d1 relative to the keyboard 13 and by a distance d2 relative to the screen 12. In this Figure 3c , the contactless antenna 11 is positioned vertically (z direction in the orthonormal frame of reference) relative to the planes (xy) of the screen and the keyboard in particular (i.e. relative to the general plane of the payment device), so as to limit its footprint on the screen, which can thus be designed with a maximum size without constraints linked to the positioning of the antenna.

[0046] This vertical positioning of the antenna is made possible by the use of an antenna support, made of non-conductive material, around which the antenna is applied.

[0047] There Figure 4illustrates in particular this antenna support, in an exploded view of a part of the payment device making it possible in particular to visualize the positioning of different elements relative to each other. Thus, when the payment device is assembled, the screen 12 is positioned on a screen support 120 and surrounded by a screen seal 121 making it possible to ensure its sealing, when it is embedded in the antenna support 110. Furthermore, the precise choice of the volume of the space created between the screen and the glass, i.e. a limited volume while ensuring the necessary distance between the antenna and the screen, also makes it possible to overcome possible condensation problems. In addition, the contactless antenna 11 is applied around its support 110, for example at the level of a sort of notch 1101 provided on the upper periphery of the support 110.To do this, the dimensions of the antenna 11 are adapted so that it is held on its support when it is inserted into this notch 1101. Thus, the contactless antenna can be supplied flat with the other components of the payment device, so as to be shaped at the time of its integration. It is then folded to take the shape and dimensions of the notch 1101 provided to accommodate it in the antenna support 110.

[0048] Furthermore, one face of the support 110 is constituted by a window 111 corresponding to the window through which the contactless payment logo is visible coming from the screen 12. This window 111 therefore corresponds to the window on which the user can place his bank card for a contactless payment. Finally, a sealing enclosure 112, described in more detail below in relation to the Figure 5, helps to prevent possible risks of water infiltration and condensation that could reach the screen or even the electronic card to which the antenna is connected.

[0049] All these elements illustrated in Figure 4 are made of non-conductive material, for example Polycarbonate or elastomer. In this way, the assembly of these elements does not include any metallic material that could interfere with the contactless antenna.

[0050] As previously stated, the contactless antenna is therefore positioned on an antenna plane P-CLESS raised by a distance d2 from the screen plane P-Say,which generates a distance of 2 close to d2 between the screen 12 and the window 111. This distance of 2 therefore corresponds substantially to the height of the antenna support 110, because the window 111 corresponds to the upper face of the antenna support 110 and the lower, opposite face corresponds to the screen 12 which is embedded therein. This configuration has a significant advantage in terms of robustness of the screen because it is located away from the front face of the payment terminal and therefore protected from possible acts of vandalism. On the other hand, this distance d'2 between the glass and the screen also has the following drawbacks, which the inventors have been able to remedy: a potential problem of condensation and water infiltration, because the antenna is close to the glass and condensation inside the payment device housing risks running down the antenna to the screen, or even the electronic card. A solution to this problem lies in the implementation of a sealing enclosure 112 at the base of the antenna, at the level of the part of the antenna which connects it to the electronic card. This sealing enclosure 112 corresponds for example to an overmolding, in a non-conductive material, at the base of the antenna to guarantee its sealing. Figure 5 illustrates more particularly this sealing enclosure 112 at the base of the antenna, as well as the lateral distance d3between the contactless antenna 11 and the screen 12, making it possible to move the contactless antenna 11 even further away from the screen 12 and therefore to limit mutual interference. This sealing enclosure 112 therefore comprises an opening in which the contactless antenna is inserted, up to its connection to the electronic card. It is therefore, in this embodiment, the “vertical” extension of the antenna which is protected by this sealing enclosure 112. Indeed, the keyboard 13 constitutes a sealed zone protected by a membrane, with respect to the outside. The contactless antenna 11 must connect in this sealed zone and the sealing enclosure 112 makes it possible to prevent the passage of the antenna in this sealed zone from degrading its performance.a problem of distance between the display of the contactless logo on the screen and the glass on which the user places his card, this distance being governed by the standards of contactless payment defining in particular constraints of positioning of the contactless logo in relation to the antenna. However, in the configuration described here, the logo displayed on the screen is far from the contactless antenna, but its visibility through the glass makes it possible to use the external surface of the glass as a measurement reference and thus to comply with the standard.

[0051] There Figure 6illustrates the main elements making up the payment device according to the present technique, in an exploded view making it possible in particular to visualize the positioning of different elements relative to each other. It can thus be seen that the contactless antenna 11 is protected by a front cover 10A made of non-conductive material making it possible not to alter its emission performance, and by a front seal 10A1 (for example made of elastomer). Furthermore, it is also noted that the contactless antenna 11 is distant from the rear metal parts of the housing of the payment device, and in particular from the front face 130 made of stainless steel of the keypad 13 (for example made of silicone), from the front reinforcement plate 131 of the keypad 13, from the metal keys 132 of the keypad 13, from the rear reinforcement plate 133 of the keypad 13 and from the rear cover 10B itself.It is repeated here that the case is metallic to provide optimal impact resistance, and that this metallic presence is possible thanks to the planned distance from the contactless antenna. The material of the rear case 10B is therefore chosen to be the most resistant possible in relation to the cost that can be supported.

[0052] The network of security domes 134 (designed to protect the keyboard against intrusion attempts intended, for example, to insert spy devices into the keyboard) is, for example, a flexible (or flex) part made of polyimide, and the rear seal 10B1, intended to be inserted into the rear cover 10B, is, for example, made of elastomer like the front seal 10A1.

[0053] The payment device according to the present technique must also comply with the constraints of integration into a payment terminal specified in particular by the association "EVA" (for "European Vending & coffee service Association", in English) or the constraints of other formats historically used by other manufacturers. In particular, the constraints of robustness to vandalism are very strict and the inventors were faced with the need to find a non-conductive material sufficiently strong to replace the metal for the front 10A case of the payment device.

[0054] In order to meet the IK10 resistance index constraints in particular, several plastic materials have been studied, such as the "Thermohards" family, which are not suitable due to the lack of finesse in the production of the parts and the integration constraints required, and the "Thermoplastics" family.

[0055] Several thermoplastic materials were studied, such as Polycarbonate, Polycarbonate with glass fibers (PC GF) and Polycarbonate / Acrylonitrile Butadiene Styrene (PC / ABS). Polycarbonate with glass fibers (PC GF) proved to be the most resistant to attacks by sharp objects (knives or scissors) but also the most sensitive to flame. Polyurethane resins of different hardnesses were also studied, but their fragility to certain vandalism attacks did not allow their use to be validated. The material chosen therefore results from a compromise between robustness and manufacturing constraints.

[0056] Furthermore, electrostatic discharge (ESD) considerations also had to be taken into account, since the front part of the payment device housing is made of non-conductive material. Indeed, in the present solution, the first metal part approached by the user when placing their card during contactless payment is the contactless antenna located near the glass. The contactless antenna, and more broadly the contactless payment module, is therefore the first area of ​​the payment device in which the user discharges (like the card reader during a payment with card insertion, this reader comprising metal parts).However, multiple and repeated electrostatic discharges are likely to seriously damage the contactless payment module and the inventors have implemented a solution to avoid this drawback: the midpoint of the contactless antenna is connected to the ground of the electronic card of the payment device, for example according to the diagram illustrated in . Figure 7 .

[0057] Furthermore, the payment device of this technique also meets the constraints of combating fraud and in particular the installation of spy devices on the keyboard.

[0058] To do this, at least one of the following three techniques is implemented, as illustrated respectively in the Figures 8a to 8c , allowing a person in charge of maintenance and occasional monitoring (for example once a day) of the payment terminal 20 to detect such a spy device, such as for example a fake keyboard: an external backlight module 30a located above the keys of the keyboard 13. Thus, if a false keyboard is glued over the keyboard 13, the false keyboard modifies and in particular limits the lighting on the top of the keyboard, which can be easily detected by simple observation of the payment terminal; a rim 30b forming part of the belt on the front face of the payment device and having a cutout at the bottom of the keys of the keyboard 13, also facilitating access to the keys. Thus, if a false keyboard is glued over the keyboard 13, the false keyboard is flush with this rim 30b, which can be easily detected by simple observation of the payment terminal; the addition of at least one embossing 30c on the keyboard 13, for example two raised triangles located on either side of the keys of the keyboard 13.If a fake keyboard is glued over keyboard 13, this fake keyboard hides these embossings, which can be easily detected by simple observation of the payment terminal.

[0059] Finally, the payment device according to the present solution comprises, in a known manner and not described here, several security loops and several opening detection systems, located at the level of different sensitive elements such as for example the rear part of the case, the electronic card, the window, the keyboard, etc. The contactless payment module is also considered a sensitive element, its positioning at the front of the payment device thus also protects it from possible attacks from the rear of the payment device. This makes it possible in particular to compensate for the absence of a so-called "commissioning" solution intended to detect any attempt to remove the payment device from the payment terminal in which it is integrated, a solution which has become non-mandatory.

[0060] The features described above make it possible to address the technical problem of providing an electronic payment device in a single housing, having all the required functionalities including contactless payment and intended to be integrated into an unattended payment terminal. Thus, the positioning of the contactless antenna makes it possible to meet the required operational conditions, in terms of emission performance, by limiting interference with the essential metal parts of the payment device housing and the unattended payment terminal itself, as well as by limiting reciprocal interference with the screen, while ensuring optimal visibility of the screen, optimal robustness to bad weather and acts of vandalism and electrostatic discharge without impacting the integrity of the contactless payment module. Solutions to combat hacking attempts are also implemented.
