Description

[0001] MULTI CARD FOR COMBINING MOBILE DEVICE [0002]

The present invention relates to a mobile terminal-coupled multi-card, and more particularly to a multi-card which is connectable to a mobile terminal and includes a plurality of card information.

Since the industrialization of modern society, credit card called "plastic money" has been used for money as much as money after going through rapid information and credit. As a result, the number of credit cards held by ordinary adults has also increased significantly, and the number of credit cards held by ordinary adults has increased frequently. In addition, according to the activation of marketing, issuance of various point cards became an essential marketing item in most companies based on B2C, and now it is a common means to increase sales in small shops located in the alley.

As a result, it is a reality that dozens of cards have been issued by individuals without knowing them. However, in most cases, unnecessary issuance costs are incurred, and it is also true that they are discarded and cause social costs. Furthermore, point cards and discount cards at stores that are not frequently visited frequently are not available at the time of actual visit. This phenomenon leads to the avoidance of card issuance due to troublesome and complicated card management from the viewpoint of the consumer and wastes and unreasonableness in all aspects of demand and supply which cause unnecessary marketing cost in the view of the enterprise. In the case of credit cards, which are deemed to be relatively more efficient than actual point cards, the number of credit cards held by the credit card lender continued to increase after the credit card liquidity crisis, The number of credit cards per person is 4.9, and the total number of card issuance is about 121.23 million.

Meanwhile, the number of cards issued has been steadily increasing, but only 1.4 cards are actually used. As a result, most of the credit cards held by individuals become dormant cards, and more than 20 million (about 40 billion won) are being abandoned. It would not be an exaggeration to say that if you include a variety of cards such as debit, check, cash, and prepaid cards or cards for marketing purposes such as point cards or discount cards, astronomical costs are wasted.

Therefore, it is necessary to develop a card that can integrate various cards such as a debit card, a check card, a credit card, and a membership card.

Further, for example, when the card information transmitting unit 120 is a short-range wireless communication unit described later, the wireless communication signal embedded in the plate 110 and corresponding to the card information can be transmitted to the outside.

Also, the plate 110 may be provided so that the insertion sensing unit described later is exposed to the outside in a direction continuous with one end of the magnetic field generating unit (for example, a card reader insertion direction of the plate 110). The information display unit 170 and an information input unit 180, which will be described later, may be provided on one side of the front surface of the plate 110 to be exposed to the outside.

A part of the configuration exposed to the outside such as the card information transmitting unit 120, the insertion detecting unit, the information displaying unit 170 and the information input unit 180 is built in the inside of the plate 110, A control unit 150, an electric wiring (not shown), a memory (not shown), and a power unit (not shown). In the case where the plate 110 is composed of multiple layers, the electric wiring may be composed of a plurality of sheets between the layers of the plates 110, and between the respective layers of the plate 110, Via).

The card information transmitting unit 120 performs a function of transmitting the card information for performing settlement or accumulation. The card information transmitting unit 120 may have various configurations that can transmit the card information to an external card reader. For example, the card information transmitting unit 120 may include a magnetic field generator, an IC chip, a short-range wireless communication unit, and the like.

The magnetic field generator includes a magnetic cell that forms a magnetic field through current flow and outputs a card information magnetic signal. The magnetic field generator may include at least one track. Each track may include its own cell to generate a magnetic signal to provide to the header of the card reader. The magnetic cells can be configured in various forms. For example, a single or a plurality of magnetic cells may be arranged on a track. Further, the magnetic cells may have various arranging directions. For example, the magnetic cell is standing up so that only a specific polarity is exposed to one side of the plate 110 (i.e., in the direction of the magnetic signal output) when a magnetic field is generated. That is, the magnetic cell may be disposed on one side of the specific plate 110 so that only a specific polarity in accordance with the current direction is exposed in the magnetic signal output direction. Further, for example, the magnetic cell may be arranged so that both polarities are exposed in the magnetic signal output direction.

(Bluetooth), a Bluetooth low energy (BLE), a beacon, a radio frequency identification (RFID), an infrared data association (IrDA), an ultra wideband (UWB) ZigBee, Near Field Communication (NFC), or the like may be used. The short-range wireless communication unit receives the new card information and transfers the new card information to the control unit 150, and the control unit 150 can perform information processing and store the new card information in the memory.

In addition, the short-range wireless communication unit is built in the plate 110 and can receive the user's biometric information from the outside. For example, when it is necessary to recognize the use of a card by a user himself or herself, the iris information of the user is received through a device such as an iris recognition device or an iris recognition smart phone interlocked with the short- The control unit 150 may determine whether the stored user iridescence information matches the stored user irises information. If the received iris information matches the iris information of the user, the control unit 150 may approve the use of the card and supply an appropriate current to each magnetic cell of the magnetic field generator.

In addition, the short-range wireless communication unit can transmit the transmission data received from the mobile terminal 200 to the outside. That is, instead of including both the multi-card 100 and the mobile terminal 200, the multi-card 100 includes a short-range wireless communication unit for payment and a multi-card 100 to the mobile terminal 200 It is possible to perform near-field communication using the short-range wireless communication unit of the multi-card 100 at the time of combining.

Accordingly, a plurality of short-range wireless communication units are included to prevent the weight of the mobile terminal 200 from becoming heavy and bulky, and the manufacturing cost can be reduced by using only one short-range wireless communication unit.

The storage unit 130 stores information necessary for using the multi-card 100. For example, the storage unit 130 may store card information used for settlement or accumulation, and may store user authentication information (e.g., a security certificate of a user). In addition, when the multi-card 100 includes a user authentication function, the storage unit 130 may store biometric information of a user for user authentication. The storage unit 130 stores a plurality of pieces of card information issued to the multi-card 100 for use by the user for settlement, accumulation, or user authentication (hereinafter referred to as settlement).

In addition, the storage unit 130 may store a program for processing and controlling the controller 150. For example, the storage unit 130 may contain an operating system for driving the multi-card 100. In addition, the storage unit 130 may provide a work space for card operations such as encryption and decryption. In addition, the storage unit 130 may be configured in the form of an IC (Integrated Circuit) chip, and may include an MPU (Micro Processor Unit) having an internal calculation function in the IC chip.

The first interface unit 140 performs a function of connecting to the mobile terminal 200 when the first interface unit 140 is coupled to the mobile terminal 200. That is, the first interface unit 140 may be in contact with or coupled to the second interface unit included in the mobile terminal 200 when the multi-card 100 is contact-coupled to the mobile terminal 200. For example, when the multi-card 100 is coupled to the mobile terminal 200, the first interface 140 of the multi-card 100 may be inserted into the second interface of the mobile terminal 200, The first interface unit 140 may be inserted into the first interface unit 140 to perform physical coupling. The first interface 140 exposed at one side of the multi card 100 may be exposed at one side of the portion of the mobile terminal 200 where the multi card 100 is coupled, When the mobile terminal 100 is connected to the mobile terminal 200, the connection can be established.

The first interface unit 140 may receive control signals of the multi-card 100 from the mobile terminal 200 or additional card information to be stored. The control signal of the multi-card 100 may correspond to various signals for controlling the multi-card 100 such as card selection, card deletion, and basic card setting.

The first interface unit 140 may receive power from the mobile terminal 200 when the mobile terminal 200 is coupled with the mobile terminal 200. That is, the first interface unit 140 can receive the power stored in the power unit of the mobile terminal 200 by contacting the second interface unit of the mobile terminal 200, The card 100 can be charged together.

The first interface unit 140 may provide the card information or the user authentication information to the mobile terminal 200 when performing mobile settlement through the mobile terminal 200. [ That is, the first interface unit 140 may transmit specific card information or specific user authentication information in the storage unit 130 selected from the mobile terminal 200 to the mobile terminal 200 for mobile settlement.

In addition, the control unit 150 may further include: The control unit 150 may perform an overall control function necessary for using the multi-card 100. The control unit 150 transmits the card information to the specific card information transmitting unit 120. In addition, the control unit 150 may perform a function of converting data received from the mobile terminal 200 into a format compatible with the multi-card 100.

For example, the control unit 150 may be provided in the plate 110 to transmit a magnetic drive current signal corresponding to specific card information to the magnetic field generating unit. The controller 150 may generate the magnetic signal generated in the magnetic field generating unit in a time-series manner through the supply of the magnetic drive current signal or the flow direction adjustment. That is, the magnetic cell 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 150 can collectively control the current direction and generate the same polarity in the magnetic signal output direction (card reader header direction) in each magnetic cell. When the magnetic field generator includes a plurality of tracks, the controller 150 may adjust a magnetic drive current signal input to each track to generate a magnetic field change in the head of the card reader corresponding to each track.

The control unit 150 can supply power to the card information transmitting unit 120 for a specific time period when the insertion detecting unit recognizes insertion of the card reader. That is, the control unit 150 can determine whether the power is supplied to the card information transmitting unit 120 after receiving the data on whether the card reader is inserted into the card reader or not, from the insertion detecting unit.

The multi-card 100 may be coupled to the mobile terminal 200 in various manners. For example, on the plate 110 of the multi-card 100, the mobile terminal 200 may be provided with a multi-card 100 insertion space, as in Fig. 6, As shown in FIG. 5, the multi-card 100 may have a fixing part 210 that can fix only a part of the area of the multi-card 100 in a state where the multi-card 100 itself is exposed to the rear surface of the mobile terminal 200. [ The fixing unit 210 may be configured in various forms for fixing the multi-card 100 to the mobile terminal 200. [

In addition, a card coupling unit 160 for coupling the multi-card 100 to the mobile terminal 200 may be included. 3 and 4, the multi-card 100 may have a card engaging portion 160 formed to have a thickness corresponding to the width of the fixing portion 210 of the mobile terminal 200 . Accordingly, it is possible to prevent the mobile terminal 200 from being thickened by the fixing portion 210 for coupling the multi-card 100.

In addition, the multi-card 100 according to an embodiment of the present invention may further include an association recognition unit. The combination recognition unit may perform a function of recognizing whether the multi-card 100 is coupled to or disconnected from the mobile terminal 200. [ For example, the multi-card 100 recognizes the association or separation with the mobile terminal 200 through the association recognition unit, and can execute a specific function or retrieve predetermined card information. That is, there may be a card type that the user desires to use when separating the multi-card 100 from the mobile terminal 200 and performing settlement (for example, when paying by scratching the card directly) There may be a card type or function desired to be used while being coupled to the mobile terminal 200. [ For example, when the multi-card 100 is coupled to the mobile terminal 200, the user can load card information to be used as a transportation card for use of public transportation, And to limit the power supply to the other card information transmitting unit 120 (for example, the magnetic field generating unit, the IC chip, etc.). As a result, the time consumed for using the multi-card 100 can be reduced, and the power consumed by the multi-card 100 can be reduced, thereby improving power efficiency.

In addition, the multi-card 100 recognizes the separation from the mobile terminal 200 through the combination recognition unit and can transmit a beacon signal through the short-range wireless communication unit. The user can move the multi-card 100 with his / her mind blinking after detaching and using the multi-card 100 from the mobile terminal 200. [ In this case, the multi-card 100 transmits a beacon signal when it is separated from the mobile terminal 200, and the mobile terminal 200 receives the beacon signal and transmits the beacon signal from the mobile terminal 200 to the multi- ) Can be measured. In addition, the multi-card 100 transmits a beacon signal having a specific intensity, so that when the beacon signal exceeds a specific distance, the beacon signal is not recognized and the user can be notified of the beacon signal. Thereby, it is possible to prevent the user from losing the multi-card 100.

In addition, the multi-card 100 according to an embodiment of the present invention may further include an insertion detection unit. The insertion detecting unit may perform a function of recognizing insertion into the card reader. The insertion detection unit can recognize the insertion of the card into the card reader in various ways. Also, when the insertion of the card reader is recognized by the insertion detecting unit, the multi-card 100 can supply power to the card information transmitting unit 120 for a specific time period during which the card settlement is performed by the controller 150. [ As a result, power can be supplied only when a card is used, and power loss can be reduced. For example, the control unit 150 can supply power to the card information transmitting unit 120 only when card settlement is performed. Hereinafter, a method in which the insertion detecting unit recognizes insertion in the card reader will be described.

The insertion detecting unit is provided with a pressure sensor, so that insertion of the card in the card reader can be recognized. The insertion sensing unit may be disposed at a specific position on the plate 110 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, and pressure may be applied to the pressure sensor by the head when the card is inserted. That is, when the card 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 insertion in the card reader and can supply power to the cell have.

Further, for example, in the case of insertion into the IC card reader to perform settlement using the IC chip, the pressure sensor may be disposed on the side surface of the multi-card 100 in the direction in which the IC chip is disposed. Accordingly, when a user or a clerk performs settlement using an IC chip, a user inserts the multi-card 100 into contact with one side of the IC card reader to detect insertion in the card reader.

In addition, for example, when the card swiping is performed dynamically, the insertion detecting unit is provided at a position adjacent to the end of the magnetic field generating unit, and when the card moves in the card reader, It is possible to detect the contact of the head. Accordingly, the multi-card 100 starts to generate a magnetic signal when card reading is started, thereby reducing power consumption.

In addition, for example, the insertion sensing unit may receive an electrical signal corresponding to the exchange of the card information magnetic signal with the header of the card reader from the magnetic field generating unit to sense insertion in the card reader. That is, the magnetic cell of the magnetic field generating portion serves as an inductive sensor, and the card information can be transmitted between the magnetic reader and the card reader header by detecting the magnetic field change.

In addition, the insertion sensing unit can utilize the pressure sensor and the inductive sensor together. Accordingly, it is possible to prevent a malfunction due to pressure applied to the pressure sensor by a configuration other than the header of the card reader, and it is possible to prevent a magnetic field change in the magnetic cell due to an object, It is possible to prevent a case where a malfunction is detected.

In addition, the information display unit 170 may further include an information display unit 170. The information display unit 170 may be provided on one side of the front surface of the plate 110 to display related information on the screen and provide the information to the user. That is, the information display unit 170 displays and outputs information processed in the multi-card 100. [ For example, when payment or accumulation is performed by inserting the multi-card 100 into a card reader, a UI (User Interface) or a GUI (Graphic User Interface) related to payment or accumulation of a card is displayed, The card information can be displayed. In this case, the information display unit 170 can display the used card name, the current payment amount, the accumulated payment amount, the user basic information, and the like. In addition, when the card merchant name to be paid through the information input unit 180 to be described later is inputted, the information display unit 170 may display a list of membership cards having a discount benefit of the merchant. When the information display unit 170 of the multi-card 100 itself performs accumulation or the like, the information display unit 170 may display a barcode, a number, or a QR code of a card to be accumulated.

Meanwhile, as described above, when the information display unit 170 and the touch pad have a mutual layer structure to constitute a touch screen, the information display unit 170 may be used as an input device in addition to the output device. If the information display unit 170 is configured as a touch screen, the information display unit 170 may include a touch screen panel, a touch screen panel controller, and the like. When the information display unit 170 is implemented with a touch screen, the user can select the card information (e.g., company logo, card appearance, card name, etc.) displayed on the information display unit 170 by touch operation, (For example, sweeping) a predetermined portion of the card by touching a portion of the touch screen displayed on the touch screen or touching the touch screen.

In addition, when the touch input method is a method of moving along a predetermined path in contact with the touch screen, the multi-card 100 changes card classification, card type, card selection, Card deselection, and so on. For example, by operating the touch screen up and down, the card classification can be changed. That is, it is possible to change the user's credit card group, the user's check card group, and the user's point card group. By manipulating the touch screen to the left or right, the card type in the card classification can be changed. That is, in the case of the credit card group, it is possible to search for and select a credit card for which settlement is to be performed by left / right operation. In addition, a card image, a company logo, or the like displayed on the information display unit 170 may be touched to select or deselect a card.

In addition, the information display unit 170 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, (E-paper). There may be two or more information display units 170 according to the embodiment of the multi-card 100. For example, the information display unit 170 may be provided on the front and back sides of the multi-card 100, respectively.

The electronic paper is an electronic device that can feel the feel of paper and can serve as a paper, and is also referred to as an e-paper. Various methods such as a method of using ink or small balls or capsules and a method of making a flat panel display thinner, such as a conventional liquid crystal display (LCD), may be applied to the electronic paper.

Further, the biometric information input unit 180 (not shown) may be further included. The biometric information input unit 180 is provided on one side of the plate 110 to perform a function of acquiring biometric information of a user. The controller 150 may compare the biometric information acquired through the biometric information input unit 180 with previously stored biometric information to determine whether to generate card information in the magnetic field generator.

For example, the multi-card 100 may include a biometric information input unit 180 that can acquire fingerprint information of a user. The biometric information input unit 180 transmits the acquired fingerprint information to the control unit 150, and the control unit 150 can determine whether the fingerprint information of the previously stored user matches the acquired fingerprint information. When the fingerprint information of the stored user coincides with the acquired fingerprint information, the controller 150 processes the specific card information to match the specific magnetic field generation method, and supplies current to each magnetic cell of the magnetic field generation unit.

In addition, the biometric information input unit 180 may be provided with biometric information from an external device, which is a camera device for recognizing the irregularities, which is difficult to embed in the plate 110. In this case, the function of the biometric information input unit 180 may be performed by a short-range wireless communication unit for communication with an external device, which will be described later.

Further, the information input unit 180 may be further included. The information input unit 180 may be provided on one side of the plate 110 to perform a function of receiving an operation from a user to select specific card information from the stored one or more card information. That is, the information input unit 180 receives input data for controlling the operation of the multi-card 100 by the user, and transmits the input data to the controller 150. The information input unit 180 may include a key pad, a keyboard, a dome switch, a touch pad (static pressure / static electricity), and may be exposed to one side of the plate 110. For example, the information input unit 180 may include a button input method for changing or selecting a card by a direction button and a selection button, a touch pad method for performing a card change or selection by receiving a user's touch operation . In particular, when the touch pad has a mutual layer structure with the information display unit 170, it may be referred to as a touch screen. When the information input unit 180 is configured as a touch screen, a desired card can be selected through a user interface operation displayed on the touch screen. Accordingly, the information input unit 180 receives a user's operation and performs a function of selecting among a plurality of card information.
