    CASE FOR MOBILE PHONE
    Field
    The present description generally relates to the recharging of microcircuit cards (smart cards) equipped with a rechargeable battery and a near-field communication antenna.
    Presentation of the prior art
    We can distinguish microcircuit cards (smartcard) equipped with a near-field communication antenna according to whether or not they include a battery. A first category of cards does not include a rechargeable battery and the microcircuit can only operate when the card is in contactless communication with a terminal. A second category to which the present description applies more particularly relates to cards whose electronic circuit (s) remain supplied even when the card is not in the field of a terminal generating an electromagnetic field of communication in the near field. These cards then incorporate a rechargeable battery, typically in a thin layer.
    This battery must be able to be recharged. Today, the user must periodically place the card on the case of a charger equipped with a near-field communication antenna to ensure recharging.

    detailed description
    The same elements have been designated by the same references in the different figures.
    For the sake of clarity, only the elements useful for understanding the embodiments which will be described have been shown and will be detailed. In particular, the operation and the structure of the whole of a radiofrequency transmission chain have not been detailed, the embodiments described being compatible with the usual transmission chains. In the following description, when reference is made to the terms approximately, approximately and, on the order of, this means to the nearest 10%, preferably to the nearest 5%.
    Figure 1 is a schematic view of a smart card or smart card, equipped with a battery.
    Card 1 generally has a rectangular shape a few centimeters on the side and is thin (less than
    2-3 millimeters).
    The card 1 comprises at least one electronic circuit 12 and, in the applications targeted by this description, a battery 14, preferably a thin film battery, and an antenna 16 for contactless communication. Where appropriate, the card 1 also comprises electrical contacts 18 intended to be in contact with corresponding contacts of a terminal (not shown). The two ends of the antenna 16 are connected to the circuit 12, as are the two terminals of the battery 14.
    The representation of Figure 1 is schematic. In particular, the respective positions of the different elements may vary. Similarly, the size of the antenna 16 depends on the applications. The antenna 16 can, if necessary, be carried by one face of the battery 14 produced in thin layers.
    In the applications targeted by this description, the microcircuit card is, for example, a card usable in banking applications, storing a key to the
    B15775 - 16-TO-0885 like a token and equipped with a token value display. Another example concerns cards incorporating biometric sensors or other sensors. Yet another example relates to bank cards storing the value of an electronic wallet, etc.
    The inventors propose to take advantage of the presence, in mobile telephones or portable telephones, of a communication antenna and of a battery of capacity greater than that equipping microcircuit cards. Indeed, most card users are also equipped with a mobile phone that they have on them permanently or most of the time, so that ensuring recharging by the phone does not deprive them of the card, unlike a charging station.
    In particular, a portable telephone (smartphone) equipped with a near-field communication antenna generally carries this antenna on the rear face, typically in a rear cover of the telephone. The antenna is generally arranged at the level of the casing or shell of the telephone so as not to be screened by metallic elements. Because of these metallic elements and the fact that the antenna generally includes a reflector, it can only transmit and receive an RF signal to / from the back of the phone. The antenna is connected to the electronic transmission circuits internal to the telephone. In addition, a mobile phone has a battery. This battery can be used as a power source to recharge the battery of a microcircuit card.
    Figure 2 is a schematic perspective representation of an embodiment of a case 2 for mobile phone.
    FIG. 3 schematically represents an antenna system 3 intended to be contained in a case of the type of that of FIG. 3.
    According to this embodiment, the case 2 is a flip case, like a wallet.
    B15775 - 16-TO-0885
    The case 2 comprises a first part 22 or bottom, defining a housing 224 or receiving shell for a mobile phone (not shown) and a flap 24 articulated at the bottom 22 by a flexible hinge 26. The case 2 has, in this example, a generally rectangular shape when the flap 24 is folded over the shell to close the case 2. The bottom 22 and the flap 24 are of sufficient thickness to each integrate at least one planar antenna of an antenna system (3 , Figure 3). In FIG. 2, examples of surfaces in which these antennas are inscribed have been shown in dotted lines. In addition, the inner face of the flap 24 has at least one slot 28 for accessing a housing 29 for receiving (storing) a microcircuit card 1.
    At least one antenna 32 is integrated in the bottom 22. The antenna 32 consists of a flat conductive winding, the production of which is in itself usual. The two ends of the antenna 32 are connected by wires 36 to two ends of at least one antenna 34 integrated in the flap 24. The antenna 34 also consists of a flat conductive winding.
    The role of the antenna structure 3 is to capture the energy radiated by a contactless communication antenna (NFC - Near Field Communication) of the telephone opposite the bottom 22, and to transfer this energy to the antenna 34 of the flap 24 so that it can be received by a card 1 (more precisely by the antenna 16 of a card 1) housed in the housing 29.
    A filter 38 (typically a capacitive element) is interposed on the path of the conductors 36 connecting the two antennas 32 and 34. The role of this filter is to create if necessary an antenna system resonant preferably at a frequency identical to that of the system of near field communication used, for example 13.56 Mhz in the case of the NFC standard.
    FIG. 4 illustrates the equivalent electrical diagram of the antenna system 3 in coupling with an antenna 42 of a mobile telephone 4 placed in the housing 224. The antenna 42 is connected, on the telephone side 4, to one or more electronic circuits 44 including practice an NFC router.
    B15775 - 16-TO-0885
    The antennas 32 and 34 (Figure 3) can be different (in number of turns, surfaces and impedances). Preferably, the antenna 32 is identical (in number of turns, surface and impedance) to the antenna 42 of the telephone 4 to maximize their coupling. Preferably, the antenna 34 is identical (in number of turns, surfaces and impedances) to the antenna 16 of the card 1 always to maximize the coupling.
    The structure 3 plays the role of an element that somehow replicates the antenna 42 of the telephone in the flap 24 of the case
    2. The size and shape of the case 2 are adapted to the mobile phone model 4 for which the case 2 is intended. Similarly, the telephone model 4 conditions the position of the antenna 32 placed in the thickness of the shell 224.
    According to an alternative embodiment, the external face of the flap 24 includes a metal screen, so as to protect the card or cards contained in the case against possible piracy.
    According to another alternative embodiment, the housing 29 is accessible from the outside of the flap 24 instead of being from the inside, the external surface of the flap 24 then has the slot 28.
    According to another alternative embodiment, housing is provided on either side (inside and outside) of the flap 24.
    According to another alternative embodiment, several slots 28 (for example two) and an antenna 34 are provided, the surface of which covers approximately the receiving housing (s) 29.
    FIG. 5 illustrates the equivalent electrical diagram of an embodiment of the antenna system 3 in coupling with an antenna 42 of a mobile telephone 4 placed in the housing 224 and two microcircuit cards 1 12.
    According to this embodiment, several slots 28 (for example two) and several (for example two) antennas 34 connected in parallel are provided. In this case, the antennas 34 do not overlap, so that the cards 1 housed in the
    B15775 - 16-TO-0885 housings 29 of the flap 24, open by the slots 28, do not overlap either. Furthermore, the filter 38 is then also dimensioned to adapt the impedance and take account of this parallel connection. In practice, the number of cards 1 that can be reloaded depends on the surface of the flap 24.
    FIG. 6 illustrates the equivalent electrical diagram of another embodiment of the antenna system 3 in coupling with an antenna 42 of a mobile telephone 4 placed in the housing 224 and two microcircuit cards 1 12.
    According to this embodiment, several slots 28 (for example two) and several (for example two) antennas 34 connected in series are provided. In this case, the antennas 34 do not overlap, so that the cards 1 housed in the housings 29 of the flap 24, open by the slots 28, do not overlap either. Furthermore, the filter 38 is then also dimensioned to adapt the impedance and take account of this series connection. In practice, the number of cards that can be reloaded depends on the surface of the flap 24.
    An advantage of the embodiments described is that it is now possible to use a mobile phone case to recharge cards incorporating a battery.
    Another advantage of the embodiments described is that the cards are contained in the case in the manner of cards in a wallet and therefore do not risk falling or being lost.
    An advantage induced by the use of a mobile phone case is that the recharging of the card or cards is carried out without constraint for the user, unlike a dedicated charger obliging him to leave the cards in charge on non-transportable devices. Here, since a user generally has their phone with them, recharging is much easier.
    Another possible use of a mobile phone case according to the embodiments described is to exchange data between a mobile phone placed in the housing
    B15775 - 16-TO-0885
    224 and a microcircuit card 1 disposed in the receiving housing 29. This use is compatible with applications running on a portable telephone and allowing communication with a microcircuit card via the antenna in the near field of the telephone. For example, it can be a direct secure information exchange between the card and the phone to share sensitive data (payments, history, etc.) or the exchange of non-sensitive data linked for example to card status (remaining battery level, activation and deactivation of the battery charge, information from on-board sensors, etc.) allowing optimization of card management.
    Various embodiments and variants have been described. Certain embodiments and variants may be combined and other variants and modifications will appear to those skilled in the art. Furthermore, the practical implementation of the embodiments which have been described is within the reach of those skilled in the art from the functional indications given above. In particular, the dimensioning of the case and the antennas depends on the telephone and the cards for which the case is intended, and is within the reach of those skilled in the art.
