The plate 100 is formed in a square plate shape, and the corner portion of the square plate shape may be rounded. The plate 100 may include a configuration of a multi card such as the magnetic field generating unit 200 and the control unit 300. Plate 100 may be made of a plastic or metal plate of a resilient material, such as a general card, it may be configured by overlapping several sheets.

The plate 100 has a strip-shaped magnetic field generating unit 300 on one side of the rear surface 110, more specifically, on a side of the rear surface 110 adjacent to one side of two long sides of the plate 100. Can be arranged to be exposed. In addition, the plate 100 may be provided such that the insertion detecting unit 400 to be described later is exposed to the outside in a direction continuous with one end of the magnetic field generating unit 200 (for example, the card reader insertion direction of the plate 100). Can be. In addition, one side of the front surface 120 of the plate 100 is provided with an information display unit 500 and the information input unit 600 to be described later may be exposed to the outside.

Inside the plate 100, a part of the configuration exposed to the outside such as the magnetic field generating unit 200, the insertion detecting unit 400, the information display unit 500, the information input unit 600 is embedded, and is not exposed to the outside Components such as a control unit 300, an electric wiring (not shown), a memory (not shown), a power supply unit (not shown) may be embedded. The electrical wiring, if the plate 100 is composed of several layers, may be composed of several sheets between the layers of each plate 100, each of the layers of the plate (Via) corresponding to the wiring passage Can be connected via.

The magnetic field generator 200 generates a magnetic signal corresponding to the card information by forming a magnetic field. The magnetic field generating unit 200 is disposed adjacent to one side of one of the rear sides 110 of the plate 100, more specifically, one of two long sides of the magnetic field generating unit 300, and the rear side of the plate 100 ( Exposed to 110, the plate 100 is configured to be adjacent to the header of the card reader when passing through the card reader.

The magnetic field generator 200 includes at least one track. The track includes a single magnetic cell 210 in which an anode formed upon input of current is exposed in the output direction of the magnetic signal. That is, the single magnetic cell 210 may be disposed in a long direction over the entire track such that both poles (that is, the north pole and the south pole) generated at the time of power input are exposed to the outside.

The magnetic cell 210 may include a first layer 211; Second layer 212; And a core material 230.

The first layer 211 may include the first circuit pattern 220 on one side. The first circuit pattern 220 may be directly printed on one side of the first layer 211, and the circuit pattern 220 may be provided in the first layer. In addition, in the first layer 211, the circuit patterns 220 may be arranged in parallel in a predetermined direction.

The second layer 212 may include a second circuit pattern 220 on one side. The second circuit pattern 220 may be directly printed on one side of the second layer 212, and the circuit pattern 220 may be provided in the second layer 212. In addition, like the first layer 211, the second pattern 212 may also include a circuit pattern 220 arranged in parallel in a predetermined direction. However, when the first layer 211 and the second layer 212 are combined, each wire in the first circuit pattern and the second circuit pattern is sequentially connected so that a current can be continuously wound in a specific direction. Can be. For example, as shown in FIG. 5, after a current enters through the first circuit pattern 220 of the first layer 211, the second circuit is formed through the point 221 where the first circuit pattern and the second circuit pattern meet. Current may flow in the second circuit pattern of the layer 212. Thereafter, the current flows back to the first circuit pattern at the point 222 where the current flows through the second circuit pattern and meets the first layer. By repetition of the current flow, the current may be wound around the core material disposed between the first layer 211 and the second layer 212.

In addition, the first layer 211 and the second layer 212 may further include via holes (first via holes and second via holes). The via hole is the first layer 211 of the first layer 211 when the first circuit pattern and the second circuit pattern is provided on the surface corresponding to the outer surface when the first layer 211 and the second layer 212 is coupled A function of connecting the circuit pattern and the second pattern of the second layer 212 may be performed. That is, when the first circuit pattern and the second circuit pattern are not directly connected by the thickness of the first layer 211 or the second layer 212, they may be connected by the first via hole and the second via hole. The first via hole and the second via hole may be disposed and connected to the same position 221 when the first layer 211 and the second layer 212 are combined. Accordingly, the first via hole and the second via hole are directly matched, so that the current flows in a specific direction about the core material through the circuit pattern and the via hole.

The core material 230 may be provided in a space between the first layer 211 and the second layer 212 to enhance a magnetic field. That is, the core material 230 may be formed of a magnetic material to enhance a magnetic field formed by a current flowing continuously in the first circuit pattern and the second circuit pattern. In particular, the core material 230 may be mixed with the magnetic powder and the adhesive to provide adhesion. That is, the magnetic cell 210 may be formed by attaching, injecting, or inserting a core material in which magnetic material is mixed with an adhesive, between the first layer 211 and the second layer 212. The core material may vary in viscosity depending on the type of adhesive mixed with the ferromagnetic material or the mixing ratio of the ferromagnetic material and the adhesive. For example, in the case of generating the magnetic field generating unit by injecting the core material 230 into a specific internal space, the core material 230 produced by mixing the adhesive with the low viscosity and the magnetic powder may be used. In addition, for example, when the core material 230 mixes a highly viscous adhesive and magnetic powder so that both surfaces have an adhesive force, such as a sticker, the magnetic cell 210 may have a first layer 211 or a second layer ( It may be formed by attaching the core material 230 to one surface of 212 and combining the opposite layers. The adhesive may include all of various adhesives (eg, resin, etc.) that do not affect magnetic field generation. The magnetic powder may include iron, ferrite, nickel, cobalt, manganese, aluminum, platinum, silver, copper, zinc, lead, and the like. In addition, the magnetic powder may be made of an alloy containing the magnetic material (ie, iron, ferrite, nickel, cobalt, manganese, aluminum, platinum, silver, copper, zinc, lead).

The method of forming the magnetic cell 210 by disposing the core material 230 may be applied in various ways. However, the manufacturing method of the magnetic cell 210 is not limited to the method described later.

The first layer 211 and the second layer 212 are combined to form an internal space, and the magnetic cell 210 may be formed by injecting the core material 230 into the internal space. For example, as shown in FIG. 6, the first layer 211 and the second layer 212 include a bent region 214, so that the first layer 211 and the second layer 212 are combined when the first layer 211 and the second layer 212 are combined. The curved region 214 may face the inner space. As the core material 230 is injected and filled into the internal space, the magnetic cell 210 may be formed.

In addition, the magnetic cell 210 may be formed by directly printing the core material 230 in a specific shape on the first layer 211 or the second layer 212. That is, the magnetic cell 210 may be formed by combining the opposite layers after the core material 230 is printed with a specific size on the surfaces of the first layer 211 or the second layer 212 that are coupled to each other. The first layer 211 or the second layer 212 may have a space in which the core material 230 is to be printed. For example, as shown in FIG. 7, the first layer 211 or the second layer 212 includes a recessed print space (or a curved area 214), and the core material 230 is disposed in the print space. After filling, the magnetic cell 210 may be formed by covering it with a flat opposite layer. Also, for example, when the first layer 211 or the second layer 212 is made of a flexible material that can bend, the first layer 211 or the second layer (after the core material 230 is printed) As the 212 is bent, the magnetic cell 210 including the core material 230 may be generated between the first layer 211 and the second layer 212.

In addition, the magnetic cell 210 may be formed by attaching the core material 230 cut to a specific size to the first layer 211 or the second layer 212. For example, both surfaces of the core material 230 may be attached to each other, and the core material 230 may be cut to a specific size and simply attached to the first or second layer 212. Through this, the manufacturing process of the magnetic cell 210 is simpler than the conventional, it is possible to increase the process speed.

In addition, when the magnetic field generating unit includes a plurality of tracks, the magnetic cell 210 may include a plurality of core materials 230 (for example, core materials 230 which may be adhered to both sides) cut to a specific size. It may be disposed parallel to the layer 211 or the second layer 212, the opposite layer may be combined.

In addition, the control unit 300 may further include a. The controller 300 is provided in the plate 100 to perform a function of transmitting a magnetic drive current signal corresponding to the card information specific to the magnetic field generator 200. The controller 300 may generate a magnetic signal generated in the magnetic field generator 200 in time series by supplying or supplying a magnetic driving current signal. That is, the single magnetic cell 210 can adjust the direction of the magnetic field applied to the header of the card reader through the current control. When the magnetic field generator 200 includes a plurality of tracks, the controller 300 may generate a magnetic field change in the header of the card reader corresponding to each track by adjusting a magnetic driving current signal input for each track.

The controller 300 may generate a magnetic signal corresponding to the card information by changing the magnetic field direction according to the current direction at specific time intervals. Conventional magnetic cards adjust the period of the change in the direction of the magnetic field applied to the header of the card reader by the interval of the magnetic lines arranged in the magnetic strip during the swiping process when the card payment is performed to the card reader It's a way of delivering information. That is, among the magnetic lines in the magnetic stripe, the widely spaced magnetic lines represent "0" as binary data, and the combination of two narrowly spaced magnetic lines having different polarities represents "1" as binary data. These binary data are gathered to form numbers (numeric characters) and alpha / numeric characters (alphaphatic characters). Since the magnetic field generating unit 200 of the multi-card according to an embodiment of the present invention forms a direction of one magnetic force line in one track, users may read a card in a manner of scratching the actual card (ie, swiping). When a magnetic field change occurs in the header, a time-variant magnetic signal may be generated within a specific time interval range. In this way, the user can select the method of scraping the card or the method of plugging in the header portion of the card reader so that the card information is recognized. That is, the magnetic field generator 200 generates a magnetic field in a variable direction as the current flows, thereby causing the card reader to recognize binary data of 0 and 1.

In addition, the insertion detecting unit 400; may further include. The insertion detecting unit may perform a function of recognizing whether the card reader is inserted into the card reader. The insertion detecting unit may recognize the insertion of the card in the card reader in various ways. In addition, when the insertion in the card reader is recognized by the insertion detecting unit 400, the multi-magnetic card may supply power to the magnetic field generating unit for a specific time when the card payment is to be performed by the control unit. Through this, the power can be supplied only when the card is used, thereby reducing the power loss. For example, the controller may supply power to the magnetic field generating unit only when performing the card settlement. Hereinafter, a method of recognizing the insertion in the card reader will be described.

Insertion detection unit 400 is provided with a pressure sensor, it can recognize the card insertion in the card reader. The insertion detecting unit 400 may be disposed at a specific position on the plate through which the header of the card reader passes (or contacts). For example, a pressure sensor may be disposed above or below the magnetic field generating unit so that pressure may be applied to the pressure sensor by the header when the card is inserted. That is, when a header is inserted between the header and one side of the card reader while the header is in contact with one side of the card reader, and the header presses the card, the card recognizes the insertion in the card reader and supplies power to the magnetic cell 210. Can be supplied.

In addition, for example, in the case of dynamically swiping the card, the insertion detecting unit 400 is provided at a position adjacent to the end of the magnetic field generating unit, and the magnetic field generating unit is moved to the header when the card is moved in the card reader. The contact of the header can be detected before it is recognized. Through this, the multi-card can start to generate a magnetic signal when the card reading starts to reduce the power consumption.

In addition, the insertion detecting unit 400 may receive an electrical signal according to the exchange of the card information magnetic signal with the header of the card reader from the magnetic field generating unit to detect the insertion in the card reader. That is, the magnetic cell 210 of the magnetic field generating unit serves as an inductive sensor, and detects a magnetic field change between the card reader header and transmits card information.

In addition, the insertion detecting unit 400 may utilize a pressure sensor and an inductive sensor together. Through this, it is possible to prevent the malfunction of the pressure sensor is applied to the pressure sensor by a configuration other than the header of the card reader, and to the magnetic cell 210 by an object that changes the magnetic field other than the header of the card reader Magnetic field changes can be detected to prevent malfunctions.

In addition, as shown in FIG. 8, the magnetic field blocking layer 700 may be further included. The magnetic field blocking layer 700 may be disposed on the magnetic signal output direction side of the magnetic cell 210 to prevent the magnetic field from leaking outside. That is, since both poles of the magnetic cell 210 are exposed to the outside, a magnetic signal opposite to the desired magnetic field direction may be input at a specific point at a specific point in time, so that an area in which the opposite magnetic field direction may be detected is detected. The magnetic field generating unit may be covered with a layer which may prevent the magnetic signal from occurring outside within a specific range in which the magnetic field does not occur.

In addition, the shielding layer 800; may further include. When the magnetic field generating unit includes a plurality of tracks, the shielding layer 800 may prevent interference between the tracks. That is, when the magnetic field generating unit includes a plurality of tracks, the magnetic field generated by the magnetic cell 210 of each track may interfere with the card reader header corresponding to the adjacent track, thereby reducing the recognition rate. Therefore, the multi-magnetic card has a shielding layer 800 on the opposite side of the magnetic signal output direction, thereby preventing interference between the magnetic signals of each track. The shielding layer 800 is formed of a ferromagnetic material having a high permeability, so that a magnetic field may be changed so that most of the magnetic force lines pass through the shielding layer 800. Accordingly, as shown in FIG. 9, the width of the magnetic field generated in the magnetic cell 210 of each track is narrowed, thereby reducing the influence on the adjacent tracks.

In addition, as shown in Figure 2, the information display unit 500; may further include. The information display unit 500 may be provided on one side of the front surface of the plate, and perform a function of displaying related information on a screen and providing the information to a user. That is, the information display unit 500 displays and outputs information processed by the multi-card. For example, in the case of performing a payment or accumulation by inserting a multi-card into the card reader, the card information displaying a user interface (UI) or a graphic user interface (GUI) related to card payment or accumulation or displaying payment or accumulation is displayed. I can display it. In this case, the information display unit 500 may display the use card name, the current payment amount, the cumulative payment amount, and basic user information. In addition, when inputting the name of the card merchant to pay through the information input unit 600 to be described later, the information display unit 500 may display a list of membership cards with a discount of the merchant. In addition, when performing the accumulation, such as the information display unit 500 of the multi-card, the information display unit 500 may display a bar code, a number, or a QR code of the card to be accumulated.

Meanwhile, as described above, when the information display unit 500 and the touch pad have a mutual layer structure and constitute a touch screen, the information display unit 500 may be used as an input device in addition to the output device. If the information display unit 500 is configured as a touch screen, the information display unit 500 may include a touch screen panel and a touch screen panel controller. When the information display unit 500 is implemented as a touch screen, the user can select card information (for example, a company logo, a card appearance, a card name, etc.) displayed on the information display unit 500 by a touch operation, and the card change key. The card may be changed by touching a portion on the touch screen marked with or by touching the touch screen and moving (eg, sweeping) along a predetermined path.
