    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to the field of smart cards or similar to provide dynamic information transmitted to the carrier through a display device or other such bank cards with a dynamic security code.
    STATE OF THE ART
    In the field of banking security, the manufacturers of credit cards show some ingenuity, however limited in practice, both from a software point of view material.
    Indeed, faced with the possibility of security code copy for example, card manufacturers have implemented cards whose security code, commonly called cryptogram or CW of the English "Gard Verification Value" is not plus static data printed on the card, but dynamic data generated by the card at the time of confirmation of a bank transaction and displayed on a screen most often included in the card itself.
    This new type of bank card provides an additional degree of security but at the cost of increased manufacturing complexity. Indeed, as presented in the document US 2014/0279555 A1, these dynamic security code cards now include a display screen, a battery pack and usually a button triggering the generation of a new security code from static data contained in a memory block of the card and dynamic data also from an electronic module included in the card. These dynamic data are most often time stamp data provided by an internal clock to the bank card.
    Although these cards of a new kind bring an additional level of security, their theft does not prohibit the generation of a new code for the fraudulent use of the stolen card.
    Thus in the face of this disadvantage, some card manufacturers have added an extra level of security. This is a personal code that the user must enter via a device type keyboard included by credit card. Once this personal code is entered, a new dynamic security code is generated and displayed on the card. This additional degree of security tends to make the manufacture of this type of card significantly more complex. The manufacturing cost is then sacrificed in favor of safety.
    There is therefore a real problem in terms of manufacturing cost and design of bank cards dynamic security code with a security against theft of the card itself.
    The present invention solves at least in part these two issues that are the security and design of bank cards dynamic security code.
    SUMMARY OF THE INVENTION
    The present invention relates to a device comprising a physical medium and, carried by said support, at least one electronic chip comprising at least one memory module and at least one processor configured to implement at least one computer program contained in the at least one memory module, said computer program being configured to produce at least one result from data, said device comprising at least one display module configured to display said at least one result, said device being characterized in that it comprises at least one radio antenna configured to receive at least one electromagnetic signal, said at least one electromagnetic signal being configured to electrically power said display module.
    The present invention makes it possible to suppress any type of energy storage of the device by allowing it to be powered by an external source in the form of electromagnetic waves. The present invention is thus energized by an electromagnetic wave and provides computing and information display functions without requiring battery or energy storage. This then makes industrial production of the present invention simple, reliable and inexpensive. The use of batteries has shown problems of pollution, recycling and security of property and people. The invention has made it possible to integrate a display on a card without even requiring an electrical storage thereon for this purpose, which could a priori seem incompatible.
    Many areas of application can be envisaged: - Display of a dynamic security code; - Display of the number of points of a driving license; - Display of an electronic purse balance; - Display of a contract on a transport card; - Display of loyalty points; - Display a validity date.
    In general, the present invention finds for application the display of any unit of value or time on a medium that does not have energy storage.
    In the case of bank cards, the present invention allows the generation of a dynamic security code at a display of the card itself without resorting to a battery or other means of energy storage.
    Indeed, the present invention facilitates the design and life of dynamic security code display cards by subtracting any energy storage from the card itself.
    This advantage is obtained by an external power supply in the form of electromagnetic waves emitted by a portable communication device or not electronic terminal type or mobile phone for example.
    The present invention thus allows the wireless power supply, without battery and without storage module of a device, preferably a bank card, with dynamic information display. From a security point of view, and according to a preferred case of the present invention, the display of a dynamic security code no longer requires only the bank card itself but also the user's portable communication device. , which therefore makes the theft of the bank card only useless in the case where the energization of the card and the dynamic data transfer require a device specific to the user.
    Indeed, advantageously, a pairing is performed between said bank card and the smartphone of the user for example. This pairing preferably requires a user-specific access code so that the energization of the card and the dynamic data transfer, and therefore the generation of a dynamic security code, can only be carried out from a portable communication device previously paired to said bank card by the user.
    The present invention also relates to a system comprising at least one device according to the present invention and at least one communication device, preferably portable, configured to transmit to the at least one device at least one electromagnetic signal configured to feed the at least one device. least one device and to transmit at least one dynamic data item to the at least one device.
    The present invention also relates to a method for creating a security code for the confirmation of a bank payment implemented by at least one user from at least one device according to the present invention comprising at least one electronic chip and at least one display module and from at least one computer server, and at least one communication device in communication with said at least one computer server, said method being characterized in that it comprises at least the following steps: the device is brought to radiofrequency communication range with at least one device, preferably portable, communication by said at least one user; - The device receives at least one electromagnetic signal emitted by said at least one portable communication device, said at least one electromagnetic signal being configured to electrically power said at least one display module; Said electronic chip generates, from static data and dynamic data, a security code; - The device displays the new security code on its display module.
    The present invention thus makes it possible to design a bank card with a simpler, cheaper, dynamic security code display and whose service life is increased by the absence of a battery mainly. In addition, the present invention provides an additional degree of security for triggering the generation of a new security code making it unnecessary to steal the bank card alone.

The display module 140 is driven by the electronic chip 120 which uses this energy, at least in part, to modify the information displayed by the display module in order to display the cryptogram that has just been generated.
    So that the bank card 100 is able to receive this or these electromagnetic signals (220, 220a, 220b), it must be brought into contact, that is to say radiofrequency communication port, with the smartphone. This communication range is specific to the type of radio frequency technology used.
    According to one embodiment, the device can be produced according to the technical characteristics described in the ISO 14443 standard and / or the energy required for the operation of said device is provided by at least one electromagnetic signal whose characteristics are described in the IS014443 standard.
    FIG. 4 illustrates, according to the present invention, a method of creating a security code for the confirmation of a bank payment implemented by a user from a bank card 100 according to the present invention, starting from a smartphone 200 for example, from a computer 400 and from a bank computer server 600 through a communication network 500 Internet type for example.
    According to one embodiment, the user uses his bank card 100 in synergy with his smartphone 200 to generate a cryptogram for the confirmation of an online payment from a computer 400 on a website for example.
    According to a preferred embodiment, a software application is started on the smartphone to prepare the emission of the electromagnetic energy wave and the at least one dynamic data.
    The generation of this cryptogram is advantageously carried out as follows: O The bank card 100 is brought to radiofrequency communication range with the smartphone 200 of the user; The bank card 100 receives at least one electromagnetic signal (220, 220a, 220b) emitted by the user's smartphone 200, the electromagnetic signal (220, 220a, 220b) being configured to electrically power a display module of the bank card and to transmit dynamic data from the smartphone 200 to the bank card 100;
    According to one embodiment, the electromagnetic signal 220 can be divided into two electromagnetic signals 220a and 220b so that one (220a) energizes the bank card 100 and the other (220b) transmits the dynamic data to the bank card 100. An electronic chip 120 present in the bank card 100 and powered by the electromagnetic signal (220, 220a), generates, from static data and dynamic data, a cryptogram; The bank card 100 then displays the cryptogram calculated on its display module 140 driven by the electronic chip 120.
    Once the user has possession of this cryptogram, he provides the website with his bank details, such as name, credit card number and expiration date and the calculated cryptogram.
    This information is then transmitted through a communication network 500, for example the Internet, and is received by a bank computer server 600 for verification. This bank computing server 600 performs a payment confirmation function by evaluating the bank data of the user and calculating from these static data and a GMT time stamp a cryptogram. If this cryptogram corresponds or is consistent with that provided by the user, then the payment is validated, otherwise no. The use of a time stamp, here GMT, thus provides a common basis for time calculation.
    According to one embodiment, in order to take into account the time difference between the generation of the cryptogram at the bank card 100 and its evaluation at the bank computing server 600, the latter can use earlier GMT timestamps in order to validate the transaction. banking on a non-instantaneous time slot thus taking into account a possible time lag. This offset window being an adjustable parameter at the bank computer server 600 itself.
    The present invention thus makes it possible, on the one hand, to simplify the production of dynamic cryptogram bank cards, to reduce their manufacturing cost and to increase their level of security by decoupling the static and dynamic data necessary for the generation of a dynamic cryptogram. . The invention is not limited to the previously described embodiments and extends to all the embodiments covered by the claims.
