Description

Multi Magnetic Card

The present invention relates to a multi-magnetic card, and more particularly, to a multi-magnetic card for generating a time-division magnetic signal corresponding to specific card information among a plurality of card information stored in the card.

After the industrialization of modern society, credit card, called "plastic money", has been increasing in utilization as much as currency with rapid informatization and credit. As a result, the number of credit cards carried by ordinary adults has also increased significantly, with the number of individuals having two or three cards and a large number of ten or more. In addition, with the activation of marketing, issuance of various point cards has become an essential marketing item for most B2C-based companies, and is now a common means of increasing sales even in small stores located in alleys.

As a result, dozens of cards are issued by individuals without their knowledge. However, in most cases, only unnecessary issuance costs are incurred, which are discarded, resulting in social costs. In addition, point cards and discount cards at stores that do not have frequent visits are not used at actual visits. This phenomenon is cumbersome for the consumer, leads to avoiding card issuance due to complicated card management, and waste and irrationality in all aspects of supply and demand, which leads to unnecessary marketing costs for the enterprise. Even in the case of credit cards, which are considered to be more useful than actual loyalty cards, since 2001, the number of credit card holders per capita increased to four. The number of credit card holders per person is 4.9 and the total number of card issuance is about 12.21 million.

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 head of the card reader when passing through the card reader.

The magnetic field generating unit 200 includes a magnetic cell 210 that forms a magnetic field through current flow and outputs a card information magnetic signal. As shown in FIG. 3, the magnetic cell 210 is erected so that only a specific polarity is exposed to one side of the plate 100 when a magnetic field is generated. That is, the magnetic cell 210 may be disposed on one side of the specific plate 200 so that only a specific polarity according to the current direction may be exposed in the magnetic signal output direction.

The magnetic field generating unit 200 may include at least one track. Each track may include a magnetic cell 210 to generate a magnetic signal to provide to the header of the card reader. The magnetic cell 210 may be configured in various forms. Hereinafter, the shapes of the various magnetic cells 210 will be described. However, the shape of the magnetic cell 210 is not limited thereto, and various shapes that may expose only a specific polarity in the vertical direction may be applied.

The magnetic cell 210 may be formed by stacking a plurality of sheets 211 including a coil pattern 212. The stacked sheets 211 in contact with each other include a coil pattern 212 wound up from one surface (for example, a bottom surface) to the other surface (for example, a top surface), and the coil patterns 212 are exposed to two surfaces. Can be. An exposed portion of the coil pattern 212 in the contacted sheet 211 may be contacted to form a coil wound in a specific direction. The coil pattern 212 may generate a pattern of winding one or more times in one sheet 211, or a plurality of sheets 211 may be connected to generate a single winding pattern.

In addition, the magnetic cell 210, a plurality of sheets 211, the coil pattern 212 is printed on one side is stacked, the coil pattern (of the adjacent sheet 211 so that current flows continuously in a specific rotation direction ( And a via hole connecting 212. As shown in FIG. 4, the coil pattern 212 may be printed on one side of the sheet 211, and the plurality of sheets 211 may be stacked. Via holes may be provided in each sheet 211 to connect the coil patterns 212 of the stacked sheets 211. Via holes may be disposed in each sheet 211 such that current flows in the sheet 211 in a predetermined direction (that is, in a specific rotational direction) as shown in FIG. 5. For example, when the coil pattern 212 is printed in a spiral form on the upper surface of each sheet 211, when a current flows in from the outside of the spiral shape, the adjacent sheet of the upper or lower adjacent end of the spiral shape ( Via holes connected to 211 may be disposed. In addition, the sheet 211 wound around the coil pattern 212 may be stacked to allow current to flow in the entire magnetic cell 210. That is, when the coil pattern 212 is wound a plurality of times in one sheet 211, the coil pattern 212 of the adjacent sheet 211 should be in the opposite direction so that the current flows in a constant direction when each layer is connected to the via hole. Can flow.

In addition, the magnetic cell 210, as shown in Figure 6, a plurality of sheets 211; And a core 220. The plurality of sheets 211 may have grooves having a specific shape. In addition, the plurality of sheets 211 may be stacked to form a space in which the core 220 may be disposed.

The sheet 211 may include a coil pattern 212 wound around a groove in which the core 220 is to be disposed. The coil pattern 212 may be printed on one surface of each sheet 211, or may be formed inside the sheet 211. The coil pattern 212 may be configured in a spiral shape to be wound, and various forms may be applied to allow a current to flow around a groove in which the core 220 is disposed. In addition, it may include a via hole connecting the coil pattern 212 of the adjacent sheet 211 so that current flows continuously in a specific rotation direction in the magnetic cell 210 in which the sheet 211 is stacked. For example, when the coil pattern 212 is printed in a spiral form on the upper surface of each sheet 211, when a current flows in from the outside of the spiral shape, the adjacent sheet of the upper or lower adjacent end of the spiral shape ( Via holes connected to 211 may be disposed. In addition, the sheet 211 wound around the coil pattern 212 may be stacked to allow current to flow in the entire magnetic cell 210. That is, when the coil pattern 212 is wound a plurality of times in one sheet 211, the coil pattern 212 of the adjacent sheet 211 should be in the opposite direction so that the current flows in a constant direction when each layer is connected to the via hole. Can flow.

The core 220 is disposed in the groove provided in the sheet 211, and may be made of a magnetic material. That is, the core 220 may perform a function of collecting a magnetic field generated by a current flowing through the coil pattern 212 of the sheet 211. In addition, the core 220 may be formed by injecting or inserting a core material mixed with a magnetic material and an adhesive into the groove after the stacking of the plurality of sheets 211. The core material may vary in viscosity depending on the type of adhesive mixed with the magnetic body or the mixing ratio of the magnetic body and the adhesive. Accordingly, the core material may be formed and inserted to correspond to the groove shape, and the core material may be injected into the groove shape with low viscosity. The adhesive may include all of various adhesives (eg, resin, etc.) that do not affect magnetic field generation.

In particular, the magnetic material may be a ferromagnetic substance. The ferromagnetic material corresponds to a magnetic material having strong magnetic properties because the magnetic moments of atoms are aligned. That is, a ferromagnetic material may correspond to a material in which magnetization remains even when the external magnetic field disappears after being strongly magnetized in the direction of the magnetic field when a strong magnetic field is applied from the outside. When a ferromagnetic material is used as a magnetic material, a dense magnetic field may be output in the magnetic signal output direction by the magnetization of the ferromagnetic material. The sheet 211 forming the magnetic cell 210 may be formed of a magnetic material having a high permeability. . Magnetic materials having high magnetic permeability are more likely to pass magnetic fields than air or other metals. As a result, most of the magnetism (ie, the magnetic field lines) passes inside the magnetic material with high permeability. Therefore, the magnetic field generated by the current flowing in the coil pattern 212 in the magnetic material having a high permeability does not escape to the outside and passes only the sheet 211 (that is, the magnetic cell 210). Accordingly, the generated magnetic field of the magnetic cell 210 may be prevented from interfering with the magnetic field of the adjacent track, and the magnetic field may be prevented from being dispersed to provide a strong magnetic signal with low power. The magnetic material having a high permeability may be a permalloy, a silicon steel sheet, an amorphous strip, a ferrite such as manganese-zinc system, or the like. When the magnetic cell 210 includes the core 220, the sheet 211 may not be formed of a magnetic material having a high permeability but may be formed of a general polyamide or the like.

In addition, each track may be composed of a single magnetic cell 210, as shown in FIG. 7, and may include a plurality of magnetic cells 210, as shown in FIG. 8. When each track is composed of a plurality of magnetic cells 210, the plurality of magnetic cells 210 may externally generate the same polarity at the same time through a magnetic driving current signal supplied from a controller. For example, as shown in FIG. 9, when the coil patterns 212 in the respective magnetic cells 210 have the same winding direction, a plurality of magnetic cells 210 are connected to each other so that current flows in the same direction, thereby causing the head of the card reader. The same polarity can be generated in the direction.

In addition, the magnetic cell 210 may further include a shielding film surrounding the side of each magnetic cell 210 to prevent magnetic field interference in the adjacent magnetic cell 210. Since the magnetic signals generated by the magnetic cells 210 in the same track may be formed in the same way, the shielding film may perform a function of preventing interference between tracks. The shielding film may be formed of a magnetic material having a high permeability. That is, the shielding film may play a role such that the magnetic field generated by the current flow in the magnetic cell 210 does not escape to the side but only upwards of the magnetic signal output direction. Therefore, the shielding film prevents magnetic field from escaping to the side, thereby preventing magnetic field interference with adjacent tracks. In particular, when the sheet 211 constituting the magnetic cell 210 is not formed of a magnetic material having a high permeability, the magnetic field interference prevention effect is large. For example, when the coil pattern 212 is included in a general polyamide sheet, since the magnetic field generated by the current flow may not be concentrated in the direction of the magnetic signal output, the magnetic cell formed of the polyamide sheet may be dispersed. A shielding film may be formed around the side part to prevent magnetic signal from being dispersed. Through this, interference between adjacent tracks can be prevented from interfering with the magnetic signal, and the strength of the magnetic signal generated in the magnetic signal output direction can also be increased.

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, as shown in Figure 10, the magnetic cell 210 can adjust the direction of the magnetic field applied to the head of the card reader through the current control. In addition, when a plurality of magnetic cells are included in a specific track, the controller 300 may collectively control the current direction to generate the same polarity in the magnetic signal output direction (card reader header direction) in each magnetic cell. When the magnetic field generator 200 includes a plurality of tracks, the controller 300 may generate a magnetic field change in the head 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 head 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 control unit 300 may supply power to the magnetic field generating unit 200 for a specific time when the insertion detection unit 400 to be described later is inserted into the card reader. That is, the controller 300 may determine whether to supply power to the magnetic field generating unit 200 after receiving data regarding whether the card reader is inserted into the card reader or adjacent to the header from the insertion detecting unit 400.

Multi-magnetic card according to an embodiment of the present invention may further include an insertion recognition unit (400). The insertion recognition unit 400 may perform a function of recognizing whether the card reader is inserted. Insertion recognition unit 400 may recognize the insertion in the card reader of the card in a variety of 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 controller 300. Through this, the power can be supplied only when the card is used, thereby reducing the power loss. For example, the controller 300 may supply power to the magnetic field generating unit only when performing a card payment. Hereinafter, a description will be given of how the insertion recognition unit recognizes the insertion in the card reader.

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. For example, a pressure sensor may be disposed above or below the magnetic field generating portion, so that pressure may be applied to the pressure sensor by the head 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 head when the card is moved in the card reader. The contact of the head 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, the shielding sheet 700; may further include. The shielding sheet 700 may be disposed on a surface opposite to a predetermined magnetic signal output direction to prevent the magnetic signal from being output in a direction opposite to the magnetic signal output direction. In the case of the magnetic card, the magnetic signal should be output only in a predetermined direction in which the magnetic is arranged. When a magnetic signal is output to a card surface on which no magnetic (ie, magnetic field generating portion) is arranged, a polarity opposite to the polarity of the magnetic signal output direction is generated on the opposite surface, so that an incorrect card number can be recognized. Therefore, in order to prevent this, the shielding sheet may be disposed on the opposite side of the predetermined magnetic signal output direction, thereby preventing the magnetic signal exposure in the opposite direction of the magnetic signal generation direction.

The placement area of the shielding sheet may include the placement area of the magnetic cells. If the placement area of the shielding sheet does not include the placement area of the magnetic cell, a part of the magnetic field generated in the magnetic cell may flow out to the opposite side of the magnetic signal output direction.

In addition, as shown in FIG. 11, when the magnetic field generating unit includes a plurality of tracks, the shielding sheet 700 may perform a function of preventing mutual interference by distorting the magnetic field distribution of each track. 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 shielding sheet 700 may be disposed on the opposite side of the magnetic signal output direction to prevent interference between the magnetic signals of each track. The shielding sheet 700 is formed of a magnetic material having a high permeability, so that a change in the magnetic field may occur so that most of the magnetic force lines pass through the shielding sheet 700. Accordingly, the width of the magnetic field generated in the magnetic cell 210 of each track can be narrowed to reduce the influence on the adjacent tracks.

In addition, the shielding sheet 700 may be disposed separately for each track. The shielding sheet 700 is magnetized by the magnetic field of the magnetic cell 210. When one shielding sheet 700 is formed for a plurality of tracks, when a magnetic signal (or polarity) generated in the magnetic cell 210 of each track is different at a specific point in time, a plurality of different magnetic fields are generated in one shielding sheet 700. ), And the magnetization may not work properly. Therefore, in order to properly prevent the interference between tracks by changing the magnetic force line distribution, the shielding sheet 700 needs to be separated on each track and provided on the opposite side of the magnetic signal output direction.

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.

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.

In addition, when the touch input method is a method of moving along a predetermined path by touching the touch screen 500, the multi-card changes card classification and card type according to a touch command input to the touch screen 500. You can change, select cards, deselect cards, and so on. For example, by operating the touch screen 500 up and down, it is possible to change the card classification. That is, the user may change to the credit card group of the user, the check card group of the user, and the point card group of the user. By operating the touch screen 500 left or right, the card type in the card classification can be changed. That is, in the credit card group, it is possible to search for and select a credit card to be settled by left and right operations. In addition, a card image or a company logo displayed on the information display unit 500 may be touched to select or deselect the card.

In addition, the information display unit 500 may include a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, and an electronic paper. (E-paper) may include at least one. In addition, two or more information display units 500 may exist according to the implementation form of the multi-card. For example, the information display unit 500 may be provided in the front part and the rear part of the multi-card.

The electronic paper is an electronic device that can feel the feeling of paper as it is and can act as a paper, also called e-paper. The electronic paper may be applied to various methods such as a method of making ink effect using a small ball or capsules and a paper effect by making a flat panel display such as a conventional liquid crystal display (LCD) thinner.

The apparatus may further include a biometric information input unit (not shown). The biometric information input unit may be provided at one side of the plate to perform a function of obtaining biometric information of the user. The controller may determine whether to generate card information in the magnetic field generating unit by comparing biometric information obtained through the biometric information input unit with previously stored biometric information.

For example, the multi-card may include a biometric information input unit capable of obtaining fingerprint information of the user. The biometric information input unit may transfer the acquired fingerprint information to the controller, and the controller may determine whether the fingerprint information of the pre-stored user matches the acquired fingerprint information. When the fingerprint information of the pre-stored user and the acquired fingerprint information match, the controller may process specific card information so as to correspond to a specific magnetic field generation method and supply current to each magnetic cell 210 of the magnetic field generator.

In addition, the camera device for iris recognition, which is difficult to be embedded in the plate-shaped plate 100, may receive biometric information from an external device. In this case, the function of the biometric information input unit may be performed by a short range wireless communication unit to communicate with an external device.

In addition, as shown in FIG. 2, the information input unit 600 may be further included. The information input unit 600 may be provided at one side of the plate to perform a function of receiving an operation from a user to select specific card information from one or more stored card information. That is, the information input unit 600 performs a function of receiving input data for controlling the operation of the multi-card by the user and transmitting the input data to the controller 300. The information input unit 600 may include a keypad, a keyboard, a dome switch, a touch pad (static pressure / capacitance), and the like, and may be exposed to one side of the plate 100. For example, the information input unit 600 is implemented by a button input method for changing or selecting a card by a direction button and a selection button, and a touch pad method for changing or selecting a card by receiving a user's touch manipulation. Can be. In particular, when the touch pad has a mutual layer structure with the information display unit 600 described above, this may be referred to as a touch screen. When the information input unit 600 is configured as the touch screen 500, a desired card may be selected through a user interface manipulation displayed on the touch screen 500. In this way, the information input unit 600 receives a user's operation and performs a function of selecting from a plurality of card information.

In addition, the wireless local area communication unit; may further include. The short range wireless communication unit may be provided in the plate and perform a function of receiving new card information or receiving user authentication information from an external device. Short-range communication technology used in short-range wireless communication unit, Bluetooth, BLE (Bluetooth Low Energy), Beacon (RF), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB) , ZigBee, Near Field Communication (NFC), and the like may be used. The short-range wireless communication unit may receive new card information and transmit the new card information to the control unit 300, and the control unit 300 may perform information processing and store the information in the memory.

In addition, the short-range wireless communication unit may be embedded in the plate 100 to receive the user's biometric information from the outside. For example, when iris recognition is necessary to check whether the card is used by the user, the user's iris information is received through a device such as a iris recognizer or a smartphone capable of iris recognition in conjunction with a short-range wireless communication unit. The controller 300 may transmit the information to the controller 300 to determine whether the previously matched user iris information. If the received iris information matches the iris information of the user, the controller 300 may approve the use of a card to supply an appropriate current to each magnetic cell 210 of the magnetic field generator 200.
