Definitions
- the invention relates to a device for storing at least one object which is designed for wireless communication, in particular for storing one or more debit cards, having a cavity which is at least partially shielded from electromagnetic waves of an environment by means of a shielding layer and in which the object can be positioned.
- a wallet for holding credit cards which has a separating element in order to enable one of several debit cards which are arranged in the wallet to be addressed in a targeted manner.
- the debit card to be addressed must be arranged in front of the separating element acting as a radio wave blocker, while the non-addressable cards are to be arranged on a rear side of the separating element so that they cannot be read out due to the separating element.
- a container for storing chip cards has become known, a chip card being arranged between mutually pivotable separating elements which shield electromagnetic waves from the chip card in a closed state and communication between the chip card and a chip card in an opened state In the vicinity of the chip card arranged reading device such as an ATM.
- the separating elements have to be opened, so that the chip card can be read by the cash machine.
- the object of the invention is to provide a device of the type mentioned at the outset, in which a debit card arranged in the device can be brought from a non-readable state to a readable state without changing a relative position between the debit card and the device.
- a device of the type mentioned at the outset in which an external antenna for wireless communication with a device arranged in the vicinity of the device and an internal antenna for wireless communication with an object arranged in the cavity are provided, the internal antenna via an electrical one Switch is electrically reversibly connectable to the external antenna in order to enable wireless communication between the device and the object.
- a switchable shielding of a debit card from a reading device such as a cash register or the like arranged in an environment thereof can take place not only as known from the prior art in that a separating element shielding electromagnetic waves is reversible between the debit card and the reader, but also in that the debit card is basically arranged in a shielding device and an external antenna connected to the environment and an internal antenna connected to the cavity are provided for the transmission of electromagnetic signals from an environment to the shielded debit card which are switchably connected to each other, so that electromagnetic waves from the environment can never reach the debit card directly, but indirectly via the electrical connection between the external antenna and the internal antenna, if a K contact between the external antenna and the internal antenna is closed.
- the switch can of course be designed both as a mechanical device or as a manually operated switch and as an electrical or electronic switch, in particular as a transistor, so that the device can also be switched, for example, by means of a smartphone.
- the switch is designed as a mechanically operated switch, so that the device can be designed entirely without a power supply.
- a signal is then transmitted from the external antenna to the internal antenna by a current induced in the external antenna due to an electromagnetic wave or an electromagnetic alternating field, which reaches the internal antenna and causes an electromagnetic alternating field or an electromagnetic wave to reach the cavity.
- a debit card arranged in the cavity which can be designed as an RFID card, for example, can be supplied with energy. Electromagnetic signals emitted by the debit card can be transmitted analogously via the internal antenna to the external antenna and from there to the reader such as a cash register, so that bidirectional communication is possible.
- the device can also be used for other wirelessly communicating objects, which can be designed as a card or with an appearance different from a card.
- the device is preferably used for NFC or RFID cards, for example for a card with which a user can be identified wirelessly at a charging terminal for electric vehicles.
- the device is usually designed for at least partial, preferably complete shielding of the cavity from electromagnetic waves with a frequency of more than 100 kHz, in particular a frequency in a range between 1 MHz and 100 MHz, preferably a frequency of about 13.56 MHz.
- Debit cards are usually flat. It has therefore been proven that the cavity is delimited by two separating elements, which each have a shielding layer for at least partial shielding of electromagnetic waves and are preferably designed to be flat.
- the separating elements are usually flat and can, for example, have a width of, for example, more than 53 mm, in particular 54 mm to 90 mm, a length of more than 85 mm, in particular 86 mm to 150 mm, and a height of less than 30 mm, in particular 0.1 mm to 10 mm, so that they can form a cavity receiving a debit card.
- the shielding layer it is not necessary for the shielding layer to completely enclose the cavity.
- one or more shielding layers are around positioned parallel to a front and a back or parallel to a largest side surface of the usually roughly cuboid separating element in such a way that they can block the passage of electromagnetic waves through the front and the back to the extent that wireless communication of a reading device such as a cash machine with a arranged in the cavity object is prevented.
- the shielding layer can in principle be designed in any way that is suitable for at least partially blocking or absorbing electromagnetic waves. It is particularly favorable if the shielding layer has a material with a permeability number of at least 4, preferably at least 50, in particular at least 100. It has been shown that a material with such a high permeability number or such a high relative permeability is particularly well suited to blocking or absorbing electromagnetic waves.
- the shielding layer preferably has a continuous layer made of such a material.
- the shielding layer preferably has a size corresponding to the object to be arranged in the cavity, in particular the size of a debit card, preferably a debit card in ID-1 format.

- a structure of the shielding layer can be provided, wherein a layer with a high magnetic permeability is followed by a metal layer, which is preferably designed to be electrically conductive, followed again by a layer with a high magnetic permeability.
- the shielding layer can be positioned, for example, on a base element formed by a plastic in order to achieve a desired mechanical stability.
- the base element can for example be produced in a 3D printing process.
- the shielding layer has ferrite, in particular a continuous ferrite layer.
- Ferrite has a high permeability number or a high relative permeability, so that a shielding layer, for example can be formed by a ferrite layer or two ferrite layers arranged on a metal layer.
- a device according to the invention can in principle be used to transmit electromagnetic waves from the environment to the cavity via the external antenna and the internal antenna at any frequencies. It is preferably provided that the external antenna and the internal antenna are suitable for receiving and transmitting electromagnetic waves with a frequency of more than 100 kHz, in particular a frequency in a range between 1 MHz and 100 MHz, preferably a frequency of approximately 13.56 MHz are. Such a frequency is usually used for transmitting data between debit cards and corresponding reading devices such as cash registers, which is why a device designed in this way is particularly suitable for receiving debit cards, credit cards and the like.
- a device can also be designed to accommodate more than one debit card.
- at least two cavities are provided in which objects can be positioned, a shielding layer being arranged between the cavities and an internal antenna for each of the at least two cavities is assigned, each internal antenna being reversibly connectable to the external antenna via an electrical switch in order to enable wireless communication between an object arranged in one of the cavities and the device.
- a connection between the cavity in which the respective card is arranged is accessible with a corresponding selector switch Indoor antenna and the outdoor antenna is made.
- connections between the further internal antennas and the external antenna are interrupted, so that only one internal antenna or one cavity is connected to the external antenna.
- a corresponding switch, with which the external antenna can be connected to one of several internal antennas can be designed as a selector switch with which the external antenna can be connected to exactly one Indoor antenna or none of the indoor antennas can be connected.
- the switch can be designed, for example, as a rotary switch or as a slide switch.
- a connection between the external antenna and each internal antenna can then usually be separated simultaneously via the switch, so that all objects arranged in the device are electromagnetically separated from the environment or cannot be read out wirelessly.
- the device has several interconnected separating elements, each separating element having a shielding layer which is suitable for at least partial shielding of electromagnetic waves, and one or more cavities are formed between the separating elements.
- the device can then be of modular construction in a simple manner, so that different devices for any number of debit cards can be produced in a simple manner by combining appropriate modules.
- the separating elements are releasably connected to one another. Depending on how many cards he would like to position in the device, a user can then easily adjust the size of the device by removing or adding individual separating elements.
- the separating elements can be detachably connected to one another in a wide variety of ways.
- a particularly simple way of connecting the separating elements to one another results when the separating elements are magnetically connected to one another.
- each separating element has a first ferrite layer over which a metal layer is arranged, a second ferrite layer being arranged over the metal layer.
- the device is suitable for receiving several, preferably at least three, debit cards in cavities that are electromagnetically shielded from one another, with an electromagnetic connection being able to be established between an environment and one or more of the cavities via a selector switch.
- the switch can be designed as a selector switch.
- each separating element is designed differently. In order to achieve a particularly simple construction, however, it is preferably provided that several separating elements are constructed in the same way.
- the device has a first element, which has the external antenna and a shielding layer that at least partially shields electromagnetic waves, and at least one second element, which has a shielding layer that at least partially shields electromagnetic waves and the internal antenna, having.
- a first separating element which can be arranged on the outside, can then be designed as the first element and all further separating elements as second elements, so that a corresponding device can be designed with only two different elements for any number of debit cards by using any number of second elements with the first element to be combined.
- the first element and the second element are usually designed in such a way that when they are connected a cavity results in which a corresponding object can be arranged.
- the switch for establishing an electrical connection between the external antenna and the internal antenna is provided on the first element.
- the at least one second element is detachably connected to the first element, with electrical contacts on the first element and on the second Element are arranged at corresponding positions in order to electrically connect the internal antenna via the contacts to the external antenna when a mechanical connection is established between the first element and the second element and the switch is closed.
- the second element has electrical contacts on a front side and on a rear side, at least one contact arranged on the front side with at least one contact arranged on the rear side is connected so that an inner antenna of a further second element, which is indirectly connected to the first element via a second element directly connected to the first element, can be indirectly electrically connected to the outer antenna of the first element.
- any number of second elements can be connected to the first element, an electrical signal being transmitted from the external antenna arranged on the first element to the last second element via second elements arranged between the first element and a last second element.
- the at least one contact on the front side is connected to a contact that is not arranged at a corresponding position on the rear side, in particular to a contact that is diagonally opposite.
- contacts on one side of the second element, in particular a front side, via which contacts a second connecting line of an indoor antenna can be connected to a second connecting line of the outdoor antenna are at an angle, i.e. not perpendicular to the front and rear, with a contact an opposite side, in particular a rear side, of the second element connected.
- the contacts are usually arranged on the front and the rear of the second element, which rear is normally approximately parallel to the front, at corresponding positions, so that an electrical connection between contacts of two second elements, which are arranged one above the other or are connected to one another over a large area, can be produced.
- a first contact arranged at a first position on a front side of a second element can be connected to the internal antenna of this second element.
- a second contact on the front side, arranged next to the first position at a second position, can be connected by means of an oblique connection in the second element to a contact on the rear side of the second element, which is located on the rear side at a position corresponding to the first position on the front side or which contact is located directly below the first position on the front.
- the internal antenna of the second element can be arranged under a topmost second element further second element can be reached via the contact arranged at the second position.
- An indoor antenna connected to the external antenna is usually connected to the external antenna via a first connecting line and a second connecting line. To disconnect the connection, it is sufficient to disconnect either the first connection line or the second connection line. It can therefore be sufficient if the correspondingly obliquely connected contacts are only provided for contacting the second connecting line of the respective internal antenna and the first connecting line of each internal antenna is always connected to the external antenna.
- a contact for connecting the first connecting line of the external antenna to the internal antenna on a front side of the second element can therefore in principle also be connected to a contact located directly below or in a corresponding position on the rear side.
