Description

[0001] RF CARD ACTIVATION DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an RF card using apparatus, and more particularly, to an RF card activating apparatus that allows a RF card to be used only as a payment card or a communication card when a plurality of RF cards are carried.

Generally, a terminal (especially a traffic terminal) having an RFID reader for a smart card using 13.56 MHz is configured with a display including an FND or a small LCD and a loop antenna for RFID, without a display for displaying smart card information.

Here, a smart card is an electronic credit card that can store a large amount of information by mounting an IC (integrated circuit) memory device. The ISO standard refers to all cards having one or more ICs. Developed in France, it is used in financial institutions, medical insurance cards, transportation cards, credit cards, and so on. It is also called an IC card or a chip card.

Compared to existing magnetic cards (magnetic cards), it has a very large memory capacity, high functionality and stability.

Smart cards are classified into memory-type smart cards, microprocessor-embedded smart cards, and interactive smart cards.

A memory type smart card is a smart card that does not have a built-in microprocessor, and includes a security logic in addition to a memory used mainly in a field that can be treated as a security such as a public telephone card or a purchase ticket. There is also a method in which only memory is stored for pure data storage such as medical insurance card.

The microprocessor-embedded smart card is a smart card that performs high-level functions such as judgment, calculation, and data protection by embedding a microprocessor and memory. The interactive smart card includes a microprocessor, a memory, an I / O protocol, A smart card capable of interactive transmission of information.

In recent years, with the development of display technology and the development of UI and product design in a terminal equipped with an RFID reader for a smart card, the size of the RFID antenna has become relatively small due to the tendency that the size of the display is increased as the size of the front surface of the terminal.

In other words, wireless non-contact type RF card has already become a typical payment method in place of money as a means of payment in public transportation means such as buses, subways, and taxis.

A public transportation card distributed worldwide is operated by receiving power in an Induced Coupling manner through a magnetic field formed from an RF reader, and for this reason, it is called an RF passive card (hereinafter referred to as RF card) It is common to perform data communication with an RF reader by a half-duplex method or a full-duflex method.

The reference resonance frequency, the power supply method, and the data transmission method used are determined according to the specification of the RF chip indicated by the data carrier, and the resonance frequency matching with the RF reader antenna, the smooth power to the reader such as the induced electromotive force intensity and sensitivity, The communication interaction is determined by the design and material of the passive antenna indicated by the coupling element.

Public transportation cards with various complex functions, which have been supplied indiscriminately and are now being distributed, are already being used in the wallets of each individual, including ones already known or not.

Suppose that you have several transport cards, for example, a prepaid transportation card issued by a bus transportation card operator, and a transportation card with a credit-deferred payment function available from a particular credit card company.

If you take a bus and put a wallet containing those two cards on the RF reader terminal of the bus, the RF reader terminal can not know which one of the two cards to use for payment, It is not possible to know which card is the card from which the occurred.

In other words, the payment will occur while the user is not aware.

If each card performs a normal operation and the performance difference is not clear, it is common that the above error process occurs. However, when the communication sensitivity difference between the cards is remarkable, or when only one of the two cards is placed in a normal recognition environment, May occur.

In the former case, the user must select a card to be paid out, withdraw it from the wallet, and make payment to the RF reader terminal separately.

This is a loss of user convenience, which is an important basis of the RF card.

Some RF passive card chips have some sort of anti-collision function that can distinguish each other when they are on one RF reader, but the reader is supposed to communicate with one card at a time for communication between the card and the reader. In the above case, since it is not possible to perform settlement for both of the two cards, it is normal that an error process is performed and a settlement is not performed when a plurality of identical function cards are present.

In addition, even if cards are issued from different issuers, it is common to share the environment of RF readers installed in buses, subways, and taxis. Therefore, users of public transport cards are required to recognize all issuance cards , Which of the cards recognized at the same time as the means of settlement to use as a means of payment thoroughly the user's taste and payment, and how to deal with the card depends on how the physical act.

Based on convenience, many RF cards have been pre-paid, debit or post-paid for traffic functions, entry / exit, and merchant payment. However, with the reckless card distribution and aggressive card marketing, cards of the same function issued by credit card companies, It became a situation where a plurality of users possessed a plurality.

If you have multiple cards with passive chips that use the same function, same frequency, or same wireless protocol in one wallet, you can use this card to communicate with an external RF wireless terminal that supports communication with one card at the same time The communication becomes virtually impossible unless the user takes out the payment from the purse or a specific card which is desired to communicate. The convenience of the spread RF wireless communication card is reduced by the convenience of use.

KR Patent Registration No. 10-0964553 (Jun. 10, 2010)

In order to solve the above problems, it is an object of the present invention to provide an RF card activating apparatus that allows a user to make a payment with a desired card in a plurality of RF passive cards.

The present invention provides an RF card activating device for distinguishing between a plurality of RF passive cards that do not want to communicate data with RF readers and preventing communication, and enabling only one card to communicate with a reader For other purposes.

In order to solve this problem, the first RF card of the present invention communicates with the RF reader, and the second RF card uses a selection device that makes communication with the RF reader impossible, By interposing between the first RF card and the second RF card.

The selection device has a magnetic force enhancing layer of a ferrite composite material on one side and eddy currents on the other side due to an external magnetic field and is made of aluminum, Or nickel, or a metal surface of a composite material containing a metal component.

The selection device may be configured such that the magnetic force enhancing layer and the radio wave interference layer are formed on both sides of a substrate on one side or are formed on different substrates and bonded to each other, A laminate of a plastic substrate or sheet for printing or marking on the magnetic force enhancing layer and the radio wave interference layer is laminated on both sides of the substrate or sheet and a transparent plastic substrate or sheet is laminated thereon for overlay Is preferably used.

The selection device may include a magnetic force enhancing layer formed parallel to a direction toward the card reader in a space located outside the card reader, a radio wave interfering layer formed on the opposite surface, and a magnetic force enhancing layer and a radio wave interfering layer Different colors are displayed separately.

The selection device includes a first bag on the front surface of the magnetic force enhancement layer, a second bag on the front surface of the radio wave interference layer, and a center of the RF card housed in the second bag is received on the center axis of the radio wave interference layer .

Therefore, according to the RF card activating apparatus of the present invention, when a plurality of RF cards are used and public transit such as bus, subway, taxi, etc. is used, due to the recognition error or error processing of the payment RF reader, the user takes out the designated card separately, There is an effect of eliminating concerns about personal security exposure, such as time and behavioral inconveniences that need to be verified, and the opening of wallets among many people.

In addition, according to the RF card activating apparatus of the present invention, the card specified by the user with the external RF reader is most commonly used as means for public transportation, and is located in the front portion of the wallet or pocket storing the card, It is very likely that the card will be the most used means among the cards that have been taken out of the card by other data interface such as a magnetic reader other than the RF reader or a contact type IC card reader based on ISO7816, It can be an effective means of meeting the aggressive marketing of credit card companies that encourage the use of cards.

According to the RF card activating apparatus of the present invention, in order to minimize the inconvenience of the user and to increase the usability of a specific card from a plurality of cards, a user can select one of several RF cards of the same function It is possible to use only a desired card as a payment or communication card.

That is, each step may occur in the same order as described, may be performed substantially concurrently, or may be performed in reverse order.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

First, the configuration of a conventional RF reader will be described with reference to the drawings.

1, a non-contact type RF card reader 20 includes an RF antenna 21, an RF receiving and card recognizing unit 22, a wireless transmitting / receiving unit 24 ), And an authentication display unit 23.

The wireless transmitting and receiving unit 24 transmits and receives data of the RF card 10 read from the RF reader 20 through the RS232C wireless port 34 attached to the host computer to and from the host computer 30.

Here, the RF card 10 has a built-in RF-IC chip and an RF antenna, and the RF receiver 22 receives data from all contactless cards conforming to the ISO 14443 standard.

In addition, the RF receiver 22 preferably includes an extended memory area (approximately 16 MB) capable of accommodating each specific code value scheme in order to recognize various kinds of RF cards.

The wireless transmission / reception unit 24 can wirelessly transmit / receive data of an RF card read through the RF antenna 21 and the RF reception unit 22 to / from a host computer (not shown), and uses a frequency of 2.4 GHz.

The authentication display unit 23 is composed of three LEDs and one buzzer, and the result can be output by the combination of these.

The host computer for transmitting and receiving data wirelessly to and from the RF card reader 20 is received via the RF receiver 22 of the RF card reader 20 and transmitted through the wireless transmitter / receiver 24 and received by the RS232C wireless port The user's identity verification data is compared with the data stored in the user authentication information storage unit of the host computer to determine whether the user is an authenticated user and to transmit another signal to the determined result.

2, the RF card reader includes a display 26 for providing information on the entire body of the terminal 20. Here, the display 26 may be implemented by an FND or a liquid crystal display (LCD).

A loop antenna 21 is formed on the outer surface of the front surface of the display 26 and an electromagnetic wave shielding portion for eliminating electromagnetic interference is formed on the rear surface of the display 11. Preferably, the electromagnetic wave shielding portion is formed on the rear portion of the display 25, and is formed on the display bezel portion

As described above, since the RF card 10 transmits and receives data to and from the RF card reader 20 wirelessly, the user can transmit several RF cards having the same function, that is, capable of simultaneously interacting with one RF reader, When you are in your purse, you only need to take out the card you want and pay for it in contact with or close to the RF reader.

However, since ordinary users store a plurality of cards in one wallet, there is no way to use only a specific card among a plurality of cards.

Therefore, the RF card activating device of the present invention is intended to use only one specific card while having a plurality of cards in the purse.

That is, a card to be used and a card not to be used are separated from each other on the basis of the selection device of the present invention, so that only the specific card to be used can be used.

Referring to the cross-sectional view of the selective device of the present invention shown in FIG. 3 and the drawings for explaining an example of use of the RF card activating device of the present invention shown in FIG. 4, the selection device 100 is formed in a plate shape, The reinforcing layer 110 is formed on the other surface of the substrate 110. An eddy current is generated on the other surface due to an external magnetic field and a metal surface Or a radio wave interference layer 120 having a metal surface of a composite material containing a metal component may be formed and adhered with an adhesive 130.

The radio wave interference layer 120 uses a metal material having excellent electrical conductivity to block or interfere with transmission and reception with the RF reader, so that the metal in the magnetic field formed from the antenna of the RF reader generates eddy current by the influence of the magnetic flux, And serves to attenuate the magnetic field to such an extent that communication with the RF card placed on the metal is impossible.

The metal used here is not limited to any material that can easily generate Eddy current, but copper, aluminum (Al), gold (Au), silver (Ag) It is also possible to use platinum (Pt) or the like, or to use conductive composite materials such as alloys and carbon nanotubes.

RF cards that do not wish to transmit or receive are disposed on one side of a layer made of a metal layer or an electrically conductive composite material as described above and possibly disposed on the opposite side of the metal layer or composite layer toward the RF reader, It could be the most effective way.

Thus, if a user-specified RF card that wants to communicate with an RF reader is placed between the RF reader antenna and the metal layer in the above arrangement, transmission and reception failures due to attenuation of the magnetic field occur like other cards.

Therefore, in order to select and transmit only the designated RF card, it is necessary to provide a separate means for preventing transmission / reception failure in the corresponding card. In the present invention, a magnetic force enhancement layer 110 is provided between the radio wave interference layer 120 and the RF reader And a designated RF card is disposed between the ferrite layer and the RF reader with a ferrite layer serving as an electromagnetic wave absorber to allow communication with the RF reader.

The ferrite layer used herein is a soft magnetized ceramic material composed of a composite material or crystal of Fe2O3 and divalent metals such as NiO, ZnO, and MnO, and can be manufactured by a manufacturing method such as sintering, printing, damping and the like.

Further, Common Metals 10 ^-5, while having a resistance of ~10 ^-4 Ωm ferrite is wide has a resistance characteristic of 1~10 ⁶ Ωm in accordance with the material for manufacturing and because these points due to the eddy current loss generated wide band , And the relative permeability of the ferrite can reach up to μ _r = 2000.

Since there is a limit frequency band that can be used depending on the ferrite material, it is necessary to judge usability based on the usable frequency according to the recommendation of the ferrite manufacturer.

The RF card activating apparatus of the present invention includes a first RF card 210 and a second RF card 220 interposed between the first RF card 210 and the second RF card 220 to form a selection device including a magnetic force enhancing layer 110 and a radio wave blocking layer 120, The first RF card 210 mounted on the reinforcing layer 110 can communicate with the RF reader 20 and one or more second RF cards 220 can not communicate with the RF reader 20 .

That is, among the plurality of RF cards, the radio disturbance layer 120 interferes with the radio wave transmission / reception so as not to communicate with the RF reader, One card that desires data communication with the reader is mounted on the magnetic force enhancement layer 110 so as not to interfere with the radio wave transmission / reception so that the RF reader can stably transmit and receive only one specific card.

With this configuration, the present invention minimizes the inconvenience of the user and increases the usability of the specific card from the various cards. In this case, the user can only settle the desired card among the various RF cards of the same function, So that it can be used as a communication card.

That is, the magnetic force enhancing layer 110 and the radio wave interfering layer 120 are laminated on both sides of the plastic material substrate or sheet 140 and bonded with the adhesive layer 130 (see FIG. 6) A plastic substrate or sheet 150 for printing or marking is laminated on the radio wave interference layer 120 and a transparent plastic substrate or sheet 160 is laminated thereon for overlay to form printed or marked information (See FIG. 7).

Although each layer is illustrated as being bonded to each layer by an adhesive layer 130, it is needless to say that the present invention is not limited to this, but may be constructed by thermocompression bonding.

In addition, in the present invention, it may be preferable to manufacture and use an integrated card such as an external card for user's convenience.

The selection device 100 forms the magnetic force enhancing layer 110 in parallel with the direction toward the card reader 20 in the space located outside the card reader 20 and forms the electromagnetic wave interference layer 120 on the opposite surface. .
