Description

Title of the invention: Disinfection device for the keyboard of an electronic payment terminal, and corresponding electronic payment terminal

The invention relates to a keyboard disinfection device, and more particularly to a keyboard disinfection device for an electronic payment terminal.

[0002] The use of payment terminals all over the world faces more than before the difficulty of protecting users from bacteria and viruses depositing on the parts used (keyboards, touch screens, etc.).

[0003] The cleaning of these terminals is usually done by spraying disinfectant products on external parts in contact with users. However, these disinfectant products often use very aggressive chemicals likely to reduce the resistance of the materials used in a payment terminal, whether surface materials in contact with users or materials located inside the terminal. , sometimes leading to recurring breakdowns requiring the replacement of terminals.

[0004] In fact, the disinfectant products projected onto the surfaces of a payment terminal can interfere in the interstices of the payment terminal and penetrate inside the terminal.

[0005] In addition, a so-called “Retail” use, for example the use of payment terminals in supermarkets or even the use of vending machines, that is to say the use of a terminal which does not is used only by the end customer in order to validate a payment, would require systematic cleaning between each passage. Such a frequency of cleaning with disinfectant products is difficult to implement.

[0006] In particular, and concerning vending machines in public places, that is to say use of the unattended self-service payment terminal, also called "unattended" use, it is difficult to envisage that an individual disinfects with a disinfectant product the keyboards of the payment terminals and other parts used by touch by the customer to validate the payment and obtain the purchased product.

[0007] It is then imperative to design a disinfection device allowing a high frequency of cleaning without projecting disinfectant products which degrade the payment terminal in advance. [0008] Note that the disinfection device must finally meet the requirements of the field of payment, which is very controlled to ensure the security of banking transactions.

[0009] The object of the invention is in particular to overcome these drawbacks.

To this end, the subject of the invention is a disinfection device for the keyboard of an electronic payment terminal, comprising:

- a power supply means;

- A support intended to project from the surface of the keyboard to be sterilized;

- a means of disinfection of the keyboard of the electronic payment terminal

- means of attachment to the electronic payment terminal, and in which the disinfection means comprises at least one UV LED and the disinfection device further comprises a means of pairing with the electronic payment terminal.

[0011] UV light makes it possible to degrade microorganisms such as yeasts or bacteria, or pathogenic viruses deposited on the keypad of the payment terminal, without requiring the intervention of human means. In addition, the means of pairing the disinfection device make it possible to ensure that the device used on the payment terminal is indeed certified by the manufacturer of the terminal and respects all the security constraints linked to the means of payment. Thus, this prevents a malicious third party from replacing the certified disinfection device with a pirate disinfection device, that is to say, for example, comprising means for viewing the code entered on the keyboard of the payment terminal.

[0012] The disinfection device for the keyboard of an electronic payment terminal according to the invention may also comprise the following optional characteristics, taken alone or in combination:

[0013] - LED U of the disinfection means emits UVc-type radiation.

[0014] Thus, UVc light makes it possible to degrade microorganisms such as yeasts or bacteria, or pathogenic viruses.

[0015] - the UV LED of the disinfection means is configured to emit in a wavelength range of 207 to 280 nm. This wavelength range is particularly effective for germicidal activity.

[0016] - the UV LED of the disinfection means is configured to emit at the wavelength chosen from 222 nm and 254 nm.

[0017] Thus, this wavelength makes it possible to particularly effectively degrade viruses present on the payment keypad.

[0018] - the disinfection device comprises means for activating and deactivating the keyboard disinfection means. [0019] Thus, this makes it possible to activate or deactivate the emission of the UVc LEDs by detecting the presence or not of a user of the payment terminal, so as to prevent a user of the payment terminal from being exposed to the UV light. Furthermore, the means for activating and deactivating the keyboard disinfection means makes it possible to limit the energy consumption associated with the use of the keyboard disinfection means, in particular the consumption of at least one UVc LED, in particular when the means of disinfection of the keyboard requires the use of several LEDs.

[0020] - the means for activating and deactivating the keyboard disinfection means comprises an infrared detector.

[0021] Thus, an infrared detector makes it possible to detect the presence or not of a user of the payment terminal without disturbing the wavelength of the UVc LEDs.

[0022] the support forms, at least in part, a code cache.

Thus, the disinfection device for the keyboard of a payment terminal makes it possible both to disinfect the surface of the keyboard of the payment terminal, and to hide the entry of the secret code from a malicious third party. Furthermore, this makes it possible to perfectly integrate the disinfection device into the payment terminal, for example by using means for fixing the existing code cover to the terminal. Consequently, it is not necessary to modify the entire payment terminal to benefit from the fixing means for fixing the disinfection device to the keyboard according to the invention of a payment terminal. In addition, to equip an entire fleet of payment terminals with disinfection devices, it suffices to replace only the existing code cache of each terminal with the disinfection device according to the invention.

[0024] - the means of pairing with the payment terminal is a Bluetooth or NFC protocol.

[0025] Thus, this makes it possible to communicate in a simple way with the payment terminal without a wired connection, so as to ensure that the disinfection device is indeed certified to be implemented on the payment terminal.

[0026] - the means of pairing with the payment terminal is communication via USB or via a jack cable.

[0027] Thus, this makes it possible to communicate in a simple way with the payment terminal by limiting the risks of interference, so as to ensure that the disinfection device is indeed certified to be implemented on the payment terminal. In addition, this allows the disinfection device to be electrically powered by a payment terminal, without having to use a battery.

[0028] - the fixing means are configured to fix the disinfection device to the payment terminal in a removable manner. [0029] Thus, the device can easily be removed and replaced if necessary.

The invention also relates to an electronic payment terminal comprising at least one disinfection device according to the invention.

[0031] This makes it possible to disinfect the surface of the keyboard of the payment terminal, without having to spray disinfectants thereon. This makes it possible to guarantee health safety for users of the payment terminal, without premature wear of the terminal by the use of disinfectant products.

detailed description

There is shown in Figures 1 and 2 a payment terminal 10 comprising a communication terminal TC and a keyboard 11 for payment terminal 10. The keyboard 11 comprises a disinfection device 12. The disinfection device 12 comprises a supply means 13 (not shown in Figures 1 and 2), a disinfection means 14 and a support 15 intended to project relative to the surface of the keyboard 11 to be sterilized. The disinfection device 12 further comprises a pairing means (not shown in Figures 1 and 2) with the payment terminal 10.

[0039] Note that in Figure 1, the keyboard 11 of the payment terminal 10 is remote from the communication terminal TC, the assembly forming the payment terminal 10.

The support 15 carries the disinfection means 14 so that the disinfection means 14 can disinfect the surface of the keyboard 11 intended to be in contact with a user. It will be noted that in the example described, the support 15 of the disinfection means 14 at least partly forms a code shield. Thus, the device of disinfection 12 for keyboard 11 of the payment terminal 10 allows both to disinfect the surface of the keyboard 11 of the payment terminal 10, and to hide the entry of the secret code by a user from a malicious third party.

In the example described, the keyboard includes physical keys. In a variant embodiment, the physical keys of the keyboard 11 can be replaced by a touch screen.

The disinfection means 14 comprises at least one UV LED. UV light makes it possible to degrade microorganisms such as yeasts or bacteria, or pathogenic viruses deposited on the keyboard 11 of the payment terminal 10, without requiring the intervention of human means.

It will be noted that in the example described, the UV LED of the disinfection means 14 emits UVc-type radiation. Indeed, UVc light makes it possible to degrade microorganisms such as yeasts or bacteria, or pathogenic viruses. It will also be noted that the disinfection means 14 can comprise one or more LEDs.

The disinfection means 14 and/or only the at least one UVc LED of the disinfection means 14, carried by the support 15, is oriented so as to emit light in the direction of the zone of the keyboard 11 intended to be in contact with a user (zone represented by dashed lines in FIGS. 1 and 2). Preferably, the support 15 has a low angle of inclination with respect to the surface of the keyboard 11 to allow both to direct the emission of UV light in the direction of the keyboard 11, without hiding the keyboard 11 for the user. Thus, when the disinfection means 14 is in operation, that is to say that the at least one LED emits light, this also prevents UV radiation from being emitted in undesired directions, for example in the direction devices sensitive to UV light or even in the direction of a person, for example the user, who is close to the disinfection device 12.

Preferably, the UV LED of the disinfection means 14 is configured to emit in a wavelength range of 207 to 280 nm. Indeed, this wavelength range is particularly effective for germicidal activity. It will also be noted that the far-UVc range, that is to say from 207 to 222 nm, is advantageous because it has the advantage of having good germicidal and virucidal activity, while limiting the harmful effects of UV light on human health when exposed to human skin or retina.

[0046] The 254 nm wavelength is also particularly interesting because it makes it possible to very effectively degrade the viruses potentially present on the surface of the keyboard 11 of the payment terminal 10. Indeed, this wavelength being the absorption wavelength of DNA and RNA present in viruses, this allows them to be degraded efficiently.

Similarly, the 222 nm wavelength is also particularly interesting because it makes it possible to very effectively degrade viruses potentially on the surface of the keyboard 11 of the payment terminal 10, while limiting the risks of its use on human health. in the event of inadvertent exposure.

Alternatively, the disinfection means 14 comprises at least two UV LEDs, emitting at two distinct wavelengths, for example one emitting at a wavelength of 222 nm and the other at a wavelength of wave of 254 nm. Thus, this allows in particular to have both an important bactericidal and virucidal activity.

There is shown in Figure 3 the payment terminal 10 of Figure 2 in exploded view. It will be noted that the support 15 can accommodate, in addition to the disinfection means 14, a means of activation and deactivation 16 of the disinfection means 14 of the keyboard 11.

The activation and deactivation means 16 of the disinfection means 14 of the keyboard 11 activates or deactivates the emission of the at least one UVc LED by detecting the presence or not of a user of the payment terminal 10, of so as to prevent a user of the payment terminal 10 from being exposed to UVc light. In the example described, the activation and deactivation means 16 of the disinfection means 14 of the keyboard 11 comprises an infrared detector. The infrared detector detects the presence or not of a user of the payment terminal 10 without disturbing the waves emitted by the at least one UVc LED of the disinfection means 14.

Thus, when a user approaches a hand to enter a code on the keyboard 11 of the payment terminal 10, the activation and deactivation means 16 deactivates the disinfection means 14 so as to prevent UV light be emitted on the hand of the user. When the user has finished entering his code and moves his hand away from the keyboard 11, the activation and deactivation means 16 activates the disinfection means 14 so as to disinfect the surface of the keyboard 11 in contact with the user after each use.

Furthermore, the activation and deactivation means 16 of the disinfection means 14 of the keyboard 11 makes it possible to limit the energy consumption associated with the use of the disinfection means 14 of the keyboard 11, in particular the consumption of energy of at least one UVc LED. Indeed, after having detected the presence of a hand and then the withdrawal of this hand, the activation and deactivation means 16 can activate the disinfection means 14, and in particular the at least one UV LED of the disinfection means 14, in order to allow immediate disinfection of the surface of the keyboard 11, according to a determined time delay. Finally, it will be noted that the disinfection device 12 is perfectly integrated into the payment terminal 10. Indeed, conventional code cache fixing means exist on the payment terminal 10. Thus, the cache fixing means -existing code can be used to fix the disinfection device 12 to the payment terminal 10. It will be noted that in the example described in FIG. 3, the disinfection device 12 is mounted on the payment terminal using means fixing 17 formed by at least one screw. As a variant, the fixing means 17 can be formed by lugs intended to be complementary to housings present on the payment terminal 10, or vice versa. Consequently, it is not necessary to change the entire payment terminal to mount the disinfection device 12 on the keyboard 11 of the payment terminal 10. In particular, the disinfection device 12 can be mounted on the payment terminal. payment 10 using existing fastening means 17, for example by replacing an existing code cover and reusing the same existing fastening means 17. It will be understood that the fixing means 17 can therefore allow the fixing of the disinfection device 12 on a payment terminal 10 existing in a removable manner. In addition, this makes it possible, to equip an entire fleet of payment terminals 10 with a disinfection device 12, to replace only the existing code cache with the disinfection device 12.

[0054] Figure 4 shows the rear face of the disinfection device 12 intended to be in contact with the zone of the keyboard 11 of the payment terminal 10. It will be noted that the disinfection device 12 further comprises a pairing means 18 with the payment terminal 10 which can be housed, in whole or in part in the support 15.

The pairing means 18 makes it possible to ensure that the disinfection device 12 used on the payment terminal 10 is indeed certified by the manufacturer of the payment terminal 10 and respects all the security constraints linked to the means of payment. . Thus, this makes it possible to prevent a malicious third party replacing the certified disinfection device 12, in particular by a pirate disinfection device, that is to say comprising for example means for viewing the code entered on the keyboard 11 of the payment terminal 10.

The pairing means 18 with the payment terminal 10 can be a module implementing a bluetooth protocol. Thus, the communication between the disinfection device 12 and the payment terminal 10 is simple, without a wired connection, so as to ensure that the disinfection device 12 is indeed certified to be implemented on the payment terminal 10.

Alternatively, the pairing means 18 with the payment terminal 10 is an NFC tag which also allows communication with the payment terminal 10 of so as to also certify that the disinfection device 12 for keyboard 11 mounted on the payment terminal 10 is a certified accessory and not a pirate device.

In another variant, the pairing means 18 with the payment terminal 10 includes communication via a USB cable or via a jack cable. Thus, the communication and the supply of electrical energy between the disinfection device 12 and the payment terminal 10 are simple, while limiting the risks of interference, so as to ensure that the disinfection device 12 is indeed certified to be implemented on the payment terminal 10. Indeed, radio emissions can disturb a payment card intended to communicate with the payment terminal 10, whether by insertion or by contactless type communication. It will be noted that in the example described, the pairing means 18 comprises a jack-type cable.

[0059] Figure 5 shows a schematic view of the disinfection device 12 associated with a communication terminal TC of the payment terminal 10.

It will be noted that the communication terminal TC of the payment terminal 10 has a power supply means 19 for an accessory of the payment terminal 10 making it possible to provide electrical energy to the power supply means 13 of the device. disinfection 12. It will be noted that all or some of the means housed or not in the support 15, in particular the power supply means 13, the disinfection means 14, the pairing means 18 and/or the activation means and deactivation 16, can be electrically powered by a battery, itself housed in the support 15 or remote, or else directly powered by the payment terminal 10, for example by induction, via a jack cable or via a USB cable . In the example described, the power supply is carried out via the jack cable. In this case, the jack cable serves only as a power supply means 13, the disinfection device 12 being electrically powered directly by a payment terminal 10, without using a battery. Indeed, in the example described, the pairing module 18 of the disinfection device 12 communicates via a so-called Bluetooth or NFC type wireless means with a pairing module or means 20 of the communication terminal TC of the payment terminal 10 and the power supply module of the disinfection device is powered via the jack cable with the power supply means or module 19 for the payment terminal accessory 10.

The invention is not limited to the embodiments presented and other embodiments will appear clearly to those skilled in the art. It is in particular possible to mount the disinfection device 12 for keyboard 11 on any type of keyboard or touch screen, for example on a keyboard of automatic vending machines. self-service or on a fuel selection keypad or touch screen of a fuel pump.
