Description

FIELD OF THE INVENTION [0001] The present invention relates to a charging method of a smart multi-card and a charging cradle performing such a method,

The present invention relates to a method for charging a smart multi-card and a charging cradle for performing such a method. To a smart multi-card charging method for easily supplying power to a smart multi-card based on a charging cradle, and a charging cradle performing such a method.

Since the industrialization of modern society, credit cards have become more and more popular with money as they have gone 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 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 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, a smart card to replace the existing card is needed.

It is an object of the present invention to solve all the problems described above.

Another object of the present invention is to facilitate charging of a smart multi-card using a charging cradle.

In order to accomplish the above object, a representative structure of the present invention is as follows.

According to an aspect of the present invention, a charging cradle for charging a smart multi-card includes a transformer structure for supplying input voltage by transforming an external power source, a power pack charging structure for charging the power pack based on the external power source, And a smart multi-card charging structure for charging the internal power of the smart multi-card based on the power source.

According to another aspect of the present invention, there is provided a method of charging a charging cradle for charging a smart multi-card, comprising the steps of: transforming the transformer structure by supplying external power to transform the input voltage; And charging the internal power supply of the smart multi-card based on the external power supply.

According to the present invention, a user can charge the smart multi-card by using only the charging cradle without an external power source. Therefore, it is possible to prevent a situation in which settlement is difficult because there is no power of the smart multi card.

For example, the display unit 120 may be provided on the front side and the rear side of the smart multi card.

The display unit 120 may be disposed on one side of the front surface of the plate 110. In particular, the display unit 120 may be disposed in an area where the IC chip is disposed on one side of the front surface of the plate 110 and the magnetic field generating unit disposed on one side of the rear surface of the plate 110. Accordingly, it is possible to prevent the display unit 120 from being damaged when the magnetic field generating unit is swiped in the magnetic card reader or when the smart card is inserted into the IC card reader. The display unit 120 may be disposed at a position on the plate 110 adjacent to a user input unit (e.g., a touch unit or a touch pad) so that the user can easily perform a touch operation while viewing the display unit 120 have.

The display unit 120 may be used as an input device in addition to the output device in a case where the display unit 120 and the touch sensor have a mutual layer structure (hereinafter, referred to as a 'touch screen').

The touch screen can receive various input operations such as touch operation, slide operation, sweep operation, knock operation, etc. from the user.

The card data output unit 160 performs a function of transmitting card information for performing payment or accumulation. The card data output unit 160 may be configured to transmit card information to an external card reader. For example, the card data output unit 160 may include a magnetic field generator, an IC chip, and the like. In addition, some modules (for example, an NFC communication module, a BLE communication module, etc.) of the wireless communication unit 170, which will be described later, can perform the function of the card data output unit 160 by transmitting the card data to the payment terminal .

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 may be standing up so that only a specific polarity is exposed to one side of the plate 110 (i.e., in the direction of magnetic signal output) at the time of generating a magnetic field. 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. For example, the magnetic cell may be arranged such that both polarities are exposed in the magnetic signal output direction.

The IC chip is capable of exchanging data with a contact card reader. That is, when the smart card 100 is inserted into the contact type card reader, the IC chip is exposed to the outside of the connector part plate 110, which is a part that can physically contact the card reader, So that direct data exchange can be performed.

The card data output section 160 can output the card data generated by the control section.

The control unit 140 is provided in the plate 110 to perform overall control functions necessary for using the multi-card. The control unit 140 transmits the card information to the specific card data output unit 160.

When a plurality of magnetic cells are included in a specific track, the control unit 140 can collectively control the current direction so that the same polarity is generated in the magnetic signal output direction (card reader header direction) in each magnetic cell. When the magnetic field generating unit includes a plurality of tracks, the controller 140 may adjust a magnetic driving current signal input to each track to generate a magnetic field change in the head of the card reader corresponding to each track.

In addition, for example, the control unit 140 may perform a function of generating information or a screen to be displayed on the display unit 120. That is, the control unit 140 may generate a card UI screen and provide the card UI screen to the display unit 120. If the user can select or set a desired UI screen configuration, the control unit 140 may generate a UI screen corresponding to the user's setting and provide the created UI screen to the display unit 120.

In addition, for example, the control unit 140 may perform a function of receiving an input operation from the user input unit 130, determining a corresponding operation, and instructing the operation to be performed. Specifically, when the user input unit 130 is a touch screen coupled with the display unit 120, the control unit 140 determines the position of the input operation received by the touch screen, the type of the input operation or the type of the input operation , It is possible to determine a control command corresponding thereto.

That is, the smart card 100 receives card data from the card information management server through the mobile terminal (for example, when the mobile terminal receives the card data from the card information management server through Wi-Fi, LTE cellular communication, And transmitted to a smart multi-card through short-range wireless communication).

In addition, the wireless communication unit 170 may perform a function of receiving user authentication information from a user terminal. That is, the wireless communication unit 170 may receive information (i.e., first user authentication information) for performing user authentication at the time of receiving new card information from the mobile terminal in the future. The user authentication information may be biometric information such as fingerprint information of the user, and may be various information that can identify the user.

Also, the wireless communication unit 170 transmits the user authentication information, which is compared with the user authentication information stored in the user terminal, to the user terminal, and receives the encrypted data and the seed data from the user apparatus in consideration of coincidence between the user authentication information . The wireless communication unit 170 receives the new card information and transfers the new card information to the control unit 140. The control unit 140 performs information processing to store the new card information in the memory.

The insertion detecting unit can recognize insertion of a card in the card reader. For example, the insertion detecting unit may include a pressure sensor to detect insertion of a card into the IC card reader. For example, a pressure sensor is attached to one side of a smart multi-card (for example, a short side adjacent to the IC chip), a smart multi-card is inserted into an IC card reader, It can be judged that the card is inserted when it is contacted with the side surface.

In another embodiment, the insertion sensing portion may be disposed at a specific location 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.

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. When the card is moved in the card reader, It is possible to detect the contact of the contact surface. As a result, the smart card starts to generate a magnetic signal when card reading is started, thereby reducing power consumption.

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.

Further, in another embodiment, 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.

The unlocking portion is provided on one side of the plate 110 and receives an unlocking operation for activating the touch operation function of the touch portion. That is, the user can activate the touch operation function by operating the unlock part before the touch part operation or the touch part operation in the case of performing the smart multi-card operation. For example, the touch unit can activate the touch operation function only when the unlock operation for the unlock unit is input from the user. Thus, an unintentional touch operation can be prevented from being input through the touch unit.

The unlocking portion may be provided with a button or a touch sensor (for example, a physical contact detection sensor). That is, when the user desires to input a touch operation, the touch operation function can be activated by pressing a button with a specific finger or touching the finger with the touch sensor.

The unlocking unit may include a fingerprint recognition module that receives the fingerprint information of the user, and may activate the touch operation function when the received fingerprint information coincides with the previously stored fingerprint information. That is, the fingerprint recognition module can receive the fingerprint information when the finger of the user is contacted, determine whether the fingerprint information matches the user's fingerprint information stored in the multi card, and determine whether the touch operation function or the entire function of the multi card is activated. This makes it possible to prevent a person other than the card owner from arbitrarily manipulating the card or performing the payment.

The charging cradle 500 may preferentially supply 100% power to the smart multi-card 520 based on external power. When the smart multi-card 520 is charged to a power greater than or equal to the first threshold percentage, the smart multi-card 520 may send a first threshold percent buffer signal to the charging cradle 500.

The charging cradle 500 may simultaneously power the smart multi card 520 and the power pack 540 after receiving the first threshold percent buffering signal. The charging cradle 500 relatively reduces the power supplied to the smart multi-card 520 as the charging state of the smart multi-card 520 approaches the buffer, and the power supplied to the charging cradle 500 increases relatively .

The charging cradle 500 may receive a charge completion signal from the smart multi card 520 after buffering of the smart multi card 520 and may buffer the power pack 540 by supplying full power to the power pack 540. [

Thereafter, after the threshold time has elapsed, the charging cradle 500 may determine whether the smart card 520 and the power pack 540 are connected. When both the smart multi card 520 and the power pack 540 are connected to the charging cradle 500, the charging cradle 500 re-supplies power to the smart multi card 520 and the power pack 540 in the above- .

FIG. 6 is a conceptual diagram illustrating an operation of a smart multi-card according to an embodiment of the present invention.

In Fig. 6, when the power available in the internal battery of the smart multi-card is reduced below the threshold ratio, the operation of the smart multi-card is started.

Referring to FIG. 6, when the power charged in the internal battery of the smart multi-card is reduced to less than the threshold ratio, the smart multi-card can change the operation mode.

Specifically, when the power charged in the internal battery of the smart multi-card is reduced below the first threshold ratio, the smart multi-card can change the operation mode to the first power saving mode 610. [

In the first power saving mode 610, an indicator for indicating power supply to the display window may be displayed. The smart multi-card can provide a magnetic emulation signal that emulates a magnetic signal corresponding to card information of a selected card among a plurality of cards. In addition, the smart multi-card can display a barcode signal corresponding to card information of a selected card among a plurality of cards through a display window.

In the first power saving mode 610, the brightness of the display may be reduced to a first rate of the magnitude of the magnetic emulation signal and / or the card information of the selected card may be reduced to a first rate.

In addition, if the power charged in the internal battery of the smart multi-card is reduced below the second threshold rate, the smart multi-card can change the operation mode to the second power saving mode 620. [ In the second power saving mode 620, an indicator for indicating power supply to the display window may be displayed. In the second power saving mode 620, the brightness of the display can be reduced to a second rate of intensity of the magnetic emulation signal and / or the card information of the selected card to a second rate.

Further, if the power charged in the internal battery of the smart multi-card is reduced to less than the third threshold ratio, the smart multi-card can change the operation mode to the third power saving mode 630. [ In the third power saving mode 630, an indicator for instructing power supply to the display window may be displayed. In the third power saving mode 630, the magnetic emulation signal is not output, only the barcode information of the card selected on the display is generated, the magnetic emulation signal is output, and the barcode information of the selected card on the display is not output Or the image of the barcode information may be reduced to a certain size.

Also, according to the embodiment of the present invention, the smart multi-card may charge internal power based on energy harvesting. The internal power of the smart card can be charged based on energy harvesting. For example, the card reader may generate a wireless signal, and the internal power source of the smart multi-card may be charged by performing an energy harvesting operation based on a wireless signal at the time of card settlement. In addition, the smart multi-card can provide the card information by switching the magnetic emulator to the active state after receiving the wireless signal of the card reader based on the wireless switching operation.

When this energy harvesting operation is performed, the time for energy harvesting may be set differently depending on the power state of the smart multi-card. To control the amount of energy harvesting, the smart card may intentionally provide payment card information after contact with the card dispenser for a period of time.

For example, when the amount of power stored in the smart card is small, the contact time with the card reader is set to be relatively longer, and the charging time based on the wireless signal generated by the card reader is relatively long . In addition, in the present invention, the contact time with the card reader for charging the internal power source may be set differently in consideration of the existing card settlement time. For example, it can be assumed that the use of card payment and smart multi-card is relatively frequent before 9:00 am after 9:00 am, and relatively few after 9:00 pm and before 9:00 am. In such a case, the time for energy harvesting can be adjusted by predicting the amount of card usage and estimating the power consumption according to the card usage amount.
