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 for most companies based on B2C, and now it has become a common means of increasing sales even in small stores located in the alley area. 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 order to solve such a problem, a smart multi card capable of storing a plurality of card information and selecting the card information has emerged.

Near Field Communication (NFC) module is a non-contact communication technology that is one of radio frequency identification (RFID) technologies. It is a communication technology that transmits and receives various wireless data within a distance of 10cm or less. The NFC is a next-generation local area communication technology that is attracting attention due to its relatively low security and relatively low cost because of its short communication distance. Since both data reading and writing functions are available, there is no need for a dongle (reader) that was previously required for RFID use. It is similar to existing short range communication technology, but it does not need to configure between devices like Bluetooth. The NFC module may perform data exchange through wireless communication with the communication device or contactless payment with the card terminal. The NFC antenna module 110 performs contactless data communication with a card reader or a communication device.

The memory module 120 functions to store information necessary for using the multi-card 100. For example, the memory module 120 may store one or more pieces of card information used for settlement or accumulation, and may store a security certificate of the user. In addition, when the multi-card 100 includes a user authentication function, the memory module 120 may store biometric information of a user for user authentication. In addition, the memory module 120 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 memory module 120 may store a program for processing and controlling the control module 150. For example, the memory module 120 may contain an operating system for driving the multi-card 100. In addition, the memory module 120 may provide a work space for card operations such as encryption and decryption.

The IC chip module 130 performs contact type data communication. That is, the IC chip module 130 exchanges data with the contact-type card terminal. When the multi-card 100 is inserted into the contact-type card terminal, the IC chip module 130 contacts the card contact portion of the contact-type card terminal and performs direct data exchange. For example, the IC chip module 130 may be exposed to the outside of the multi-card 100 to directly make physical contact with the contact-type card terminal to perform settlement.

In addition, the IC chip module 130 may have a storage space to perform a part of the function of the memory module 120. That is, the memory module 120 may be configured as an IC (Integrated Circuit) chip. Also, the IC chip module 130 may include an MPU (Micro Processor Unit) and may have its own computation function.

The display module 140 performs a function of displaying card information to the user. That is, the display module 140 displays and outputs information processed in the multi-card 100. For example, when the multi-card 100 is in the settlement mode, a UI (User Interface) or a GUI (Graphic User Interface) related to card settlement may be displayed or information of a card performing the settlement may be displayed. If the multi-card 100 is in the accumulation mode (that is, the selected card is the accumulation card), the display module 140 may display a barcode, a number, or a QR code of the card to be accumulated. In addition, if the multi-card 100 is in the user identification mode (i.e., the selected card is a user identification card), the display module 140 may display the type of the identification card. In addition, when the multi-card 100 is in the card registration mode or the card issuing mode in which a card other than the pre-stored card is added, the display module 140 displays a UI (User Interface) related to connection with the communication device or the card terminal, GUI (Graphic User Interface) can be displayed. When the multi-card 100 is in the use setting mode, the display module 140 visually provides a setting interface (UI) generated by the control module 150 so that the user can operate the user input module 160 So that the setting can be changed. The display module 140 may be configured as a graphic type or a segment type.

In the case where the display module 140 and the touch pad (that is, the user input module 160 described later) have a mutual layer structure to constitute a touch screen, the display module 140 may be used as an input device have. If the display module 140 is configured as a touch screen, it may include a touch screen panel, a touch screen panel controller, and the like. When the display module 140 is implemented with the touch screen, the user can select the card information (for example, company logo, card appearance, card name, etc.) displayed on the display module 140 by touch operation, The card can be changed by touching a portion of the touch screen on which the key is displayed or by moving the touch screen in a predetermined path (for example, sweeping).

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 may change the card classification, change the card type, , Card deselection, and the like. For example, you can change the card classification by operating the touch screen up and down. 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 display module 140 can be touched to select or deselect a card.

In addition, the display module 140 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, an electronic paper E-paper). In addition, there may be two or more display modules 140 according to the implementation of the multi-card 100. For example, the display module 140 may be provided on the front and back sides of the multi-card 100, respectively.

The control module 150 typically controls the overall operation of the multi-card 100 by controlling the operation of the multi-card 100. For example, the control module 150 may process data received from the user input module 160 and determine a command of the user. For example, the control module 150 extracts card information selected by the user from the memory module 120, processes the card information, and transmits the card information to the display module 140. The NFC antenna module 110, Or data to be transmitted and received through the IC chip module 130 can be processed. In addition, for example, the control module 150 may store data received via wireless communication or direct contact from a card terminal or a communication device in the memory module 120 of the multi-card 100.

The user input module 160 receives input data for controlling the operation of the multi-card 100 by a user, and transmits the input data to the control module 150. The user input module 160 may include a key pad, a keyboard, a dome switch, and a touch pad (static / static). Particularly, as described above, when the touch pad has a mutual layer structure with the display module 140 described later, it can be called a touch screen. For example, the user input module 160 may include a button input method for performing a card change or selection 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 . The user input module 160 receives a user's operation and performs selection from a plurality of pieces of card information.

The magnetic field generating module 170 plays a role of generating a magnetic field change corresponding to specific card information. The magnetic field generating module 170 may include one or more magnetic cells that form a magnetic field through current flow to output a card information magnetic signal. The magnetic cell may comprise an inductor that generates a magnetic field.

In addition, the magnetic field generating module 170 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 may be standing up so that only a specific polarity is exposed to one side of the plate (i.e., in the direction of magnetic signal output) at the time of generation of a magnetic field. That is, the magnetic cell may be disposed on one side of a specific plate so that only a specific polarity according to the current direction is exposed in the magnetic signal output direction. Also, for example, the magnetic cell may be arranged such that both polarities are exposed in the magnetic signal output direction. The magnetic field generating module 170 may be disposed on the rear surface of the plate and may be disposed adjacent to a long side on which the curved first edge is not disposed or may not be a curved specific side for ensuring the magnetic length and performing the sweep operation in the card reader And may be disposed adjacent to other long sides. In addition, the rear magnetic field generating module 170 may be disposed so as not to overlap the display module 140 on the front surface so that the display module 140 is not damaged during the sweeping operation.

The power supply module 180 serves to supply power necessary for the operation of each component under the control of the control module 150. [

Hereinafter, the arrangement of one or more parts or modules in the multi-card 100 according to the embodiments of the present invention or the structure of the multi-card 100 will be described.

2, the multi-card 100 including the NFC antenna module 110 according to an embodiment of the present invention is formed such that the size of the NFC antenna module 110 is smaller than or equal to the size of the display module 140 And may be disposed horizontally with the display module 140. In the conventional structure in which the NFC antenna is disposed at the rim of the card, there is a problem that the space in which the card component can be disposed becomes narrower because no other component or module can be disposed in the area where the NFC antenna is disposed.

In order to solve this problem, the NFC antenna module 110 may be formed to have a size that can be included in the display module 140, and may be disposed horizontally on the rear surface of the display module 140. That is, if the thickness of the display module 140 is thinner than the thickness of the card, the rear space may remain, so that the NFC antenna module 110 can be disposed in the rear space of the display module 140.

The multi-card 100 including the NFC antenna module 110 according to another embodiment of the present invention may be configured to detachably attach one or more modules included in the multi-card 100. That is, the configuration in the multi-card 100 may be formed of each detachable module. Modules of the same function may be formed in the same shape. 3, the control module 150 (i.e., the main module), the power supply module 180, the IC chip module 130, the display module 140, and the magnetic field generating module 170 . ≪ / RTI > Accordingly, the multi-card 100 can be rapidly produced by changing the module having the same shape with different specifications according to the request of the user or the order supplier. In addition, the multi-card 100 can be manufactured by combining plastic modules of the same shape (i.e., a module not including a configuration for performing internal functions) in place of unwanted components. Specifically, each of the modules may be formed in a PCB board of the same thickness, and a plurality of modules may be formed into a card shape when the modules are combined.

One or more configurations or modules of the multi-card 100, other than the control module 150, may be connected around the control module 150. Since the control module 150 controls the operation of other modules, the modules other than the control module 150 can be directly connected to the control module 150 to receive control commands. Also, the user input module 160 or the NFC antenna module 110 may directly transmit the received data (i.e., a user operation or a wireless communication signal) to the control module 150.

It is necessary for the control module 150 to transmit the control command to the other module and form the contact connection in order for the control module 150 to receive the data from the other module. To this end, each module may include a connection interface. The control module 150 may have a plurality of connection interfaces (i.e., the first connection interface 191) corresponding to the number of connectable modules, to which each other module can be directly connected. A module other than the control module 150 may have a connection interface (i.e., the second connection interface 192) at a position corresponding to the connection interface of the control module 150 (i.e., the first connection interface 191) have. The connection interface may be of various forms capable of data exchange or power transfer between modules. For example, the connection interface may be implemented in the form of an input / output (I / O) port conforming to a particular pin shape, and may be implemented as a contact terminal connectable via a contact.

In addition, the control module 150 and other modules may be coupled to each other by male and female structures. For example, the control module 150 may have a groove at a position where each module is to be coupled, and each module may have a shape conforming to the groove.

In addition, the control module 150 and other modules may include a first connection interface 191 or a second connection interface 192 in the male and female structures when coupled to each other by male and female structures. This allows each module to form a wired connection for power and data transfer when coupled.

In addition, the NFC antenna module 110 may be formed as a housing surrounding the side surface of the multi-card 100 to which the at least one module is coupled. If the NFC antenna module 110 is formed of a module of a specific size, the space for the other module becomes insufficient. 4, the NFC antenna module 110 may be formed as a housing surrounding the side surface of the multi-card 100 in order to secure a space in which other modules other than the NFC antenna module 110 are disposed . The housing may be formed in various shapes such as a shape that surrounds the multi-card 100 formed by connecting other modules (for example, a bumper shape for preventing an impact). The housing may include a plurality of wound NFC antennas. This allows one or more modules to remain coupled.

5, the NFC antenna module 110 is connected to a specific first connection interface 191 formed at one side of the control module 150 and is connected to a second connection interface 192, respectively. For example, the NFC antenna module 110 may include a second connection interface 192, which is a metal terminal, and a second connection interface 192 may include a first connection interface 191 provided in the control module 150 As shown in FIG. The NFC antenna module 110 receives the signal data from the control module 150 through the second connection interface 192 and can transmit the signal data to the outside.

According to the present invention as described above, the following various effects are obtained.

First, the arrangement of the NFC antennas is different from the conventional one, and the arrangement of the parts in the thin card can be made efficient. For example, by disposing the NFC antenna module in the rear space of the display module, it is possible to expand other component placement space up to the edge area of the card in which the NFC antenna is disposed. In other words, by disposing the NFC antenna at the bottom of the display area, it is possible to solve some design constraints by disposing other component elements in the antenna design area of the existing smart card.

Second, since each component constituting the multi-card is formed as a separate removable module, it is possible to quickly manufacture a multi-card according to a specification desired by a company in the B2B business. For example, the purchaser can determine the capacity of the memory module according to the desired card information storage count. If the purchaser does not include the magnetic field generating module in the desired specification, the magnetic field generating module has a separate component By combining PCB modules that do not have a magnetic field generating module, it is possible to rapidly manufacture a multi-card.

Third, by surrounding the multi-card with one or more modules surrounded by the NFC antenna module, one or more modules can be maintained in a coupled state. As each module can be separated and combined, NFC The problem that the antenna can not be arranged can be solved.
