Abstract

A contactless card is provided to enhance control in using the contactless card by embedding a switch for keeping a short or open state of the contactless card, and to prevent communication cross by enabling a user to conveniently select and use only the desired card in a contactless mode when a plurality of cards are held in a bag or a wallet. An IC chip(203) stores data and performs an operation function. An RF(Radio Frequency) antenna(202) communicates with an RF reader by electrically connecting to the IC chip through an electric signal path. A switch(206) supplies an electric contact signal to the IC chip. The IC chip connects or disconnects the electric signal path to/from the RF antenna according to the signal pattern of the electric contact signal received from the switch. The RF antenna transmits the data to the RF reader by electrically connecting to the IC chip when the electric signal path is connected, and transmits no data by electrically disconnecting from the IC chip when the electric signal path is disconnected. A PSU(Power Supply Unit) receives power from the RF reader through the RF antenna.

Can be.

In order to utilize the convenience of such a contactless card, users generally use a method of bringing a wallet or a bag close to a reader while the card is put in a wallet or a bag. However, there are many cases in which a plurality of conventional contactless cards are put into a bag or purse and used. In this case, when the wallet or bag is close to the card reader, a plurality of cards react to the reader, causing communication confusion.

As a related art for transmitting / receiving control of a contactless card, a configuration in which a user controls the operation of a contactless card by incorporating a switch in the contactless card is disclosed in US PATENT APPLICATION US 2003/0132301 A1, US2004 / 0124248 A1, and European Patent EP 1544787 A1. In order to prevent theft of card information, the related arts are all operated by operating a button-type switch operated by a user's hand to operate the card information only when the card user presses the switch. Take

Therefore, in the prior art, the above communication error may occur when a plurality of cards are simultaneously held in one wallet or bag, and the card information is transmitted only when the user presses a button by hand. There is a problem in that it is inconvenient to use due to the hassle to operate. In other words, the configuration disclosed in the prior art does not significantly differ from the use of the magnetic card by significantly impairing the convenience of the contact type.

The present invention improves the user's control of the contactless card by incorporating a switch in which the short-circuit or open state is maintained in the contactless card, and conveniently selects a desired card when carrying a plurality of cards in a bag or purse to use in a contactless manner. The purpose is to provide a non-contact card with a switch that can prevent communication cross-talk.

In order to achieve the above object, there is provided a non-contact card with a switch according to the present invention, an IC chip for storing data; A wireless antenna connected to the IC chip and communicating with a wireless reader; It is characterized in that it comprises a switch interposed between the IC chip and the wireless antenna to maintain a short or open state.

In this case, the IC chip is preferably a combination contact or non-contact combination chip, the IC chip may further include a computing device for performing a calculation function. In addition, when the switch is short-circuited, the wireless antenna is electrically connected to the IC chip to transmit data to an external wireless reader, and when the switch is opened, the wireless antenna is electrically disconnected from the IC chip to store data. Do not transmit data to the wireless reader. The non-contact card may further include a wireless power supply or battery power supply unit that receives power from the external wireless reader through the wireless antenna.

According to another aspect of the invention, the IC chip for storing data; A wireless antenna connected to the IC chip for transmitting and receiving a wireless signal with an external reader; A switch is provided between the IC chip and the wireless antenna to maintain a short circuit or an open state, and a contactless card including a smart unit for providing the contact service is provided.

In this case, the IC chip, the switch and the wireless antenna may be further connected in series to form a closed circuit, and may further include a computing device connected to the switch unit and the antenna and capable of performing its own calculation.

In addition, the switch may use a slide switch, a push button switch, and a toggle switch. The slide switch is movable in the horizontal direction and opened when moved in one direction, and in the form of maintaining a short circuit when moving in the other end. The pushbutton switch is a lock type pushbutton, and is operated by changing and maintaining a short circuit and an open state every time the button is pressed.

The contactless card further includes a power supply unit connected to the arithmetic unit and the switch, and the built-in switch adopts a push type contact switch so that the arithmetic unit recognizes that the switch is pressed and the switch is pressed whenever the switch is pressed. It can be operated to allow or block the transmission of data in the IC chip. The data also includes financial information, identification information, payment information, membership information and communication related information.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. no.

For example, the term 'card' throughout this specification, including claims, refers not only to flat rectangular cards, such as current credit cards, but also to accessories, key holders, cell phone rings and watches. Of course, it includes a non-contact data storage that can have a variety of forms, such as.

Fig. 2A is a schematic diagram showing a switched contactless card according to the first embodiment of the present invention.

As shown, the switchless contactless card includes a substrate 201, a wireless antenna 202, an IC chip 203, and a switch 206.

The substrate 201 functions to fix or seat the wireless antenna 202, the IC chip 203, and the switch 206, and may be made of a plastic material constituting the card.

The wireless antenna 202 is connected to the IC chip 203 and performs a function of communicating with an external reader by referring to data stored in the IC chip 203.

The IC chip 203 stores information related to payment of public transportation costs or personal financial information. The IC chip is basically a memory chip for data storage, but may of course include an additional computing device.

In addition, the IC chip 203 may be a non-contact combination contact chip.

The information stored in the IC chip 203 may be changed through communication with the wireless reader when the switch 206 is shorted. Rechargeable micropayment information such as, for example, information related to public transportation cost payment or credit settlement information is stored, and each data is transmitted and calculated by the wireless reader through the wireless antenna 202 connected to the IC chip 203 and the IC chip 203. Are stored in.

The switch 206 is interposed between the IC chip 203 and the wireless antenna 202 to control shorting or opening of the IC chip 203 and the wireless antenna 202. When the switch 206 is close to the external reader in a shorted state, the data of the IC chip 203 may be transmitted to the wireless reader through the wireless antenna 202 to perform processing related to payment. In addition, when the switch 206 is opened, the wireless antenna 202 and the IC chip 203 are opened so that communication with the wireless reader is impossible, and in this case, the function of the contactless card is stopped.

Fig. 2B is a schematic diagram showing a switched contactless card according to the second embodiment of the present invention. According to FIG. 2B, the non-contact card with a switch includes a substrate 201, a wireless antenna 202, an IC chip 203, a switch 206, a power supply unit 205, and a magnetic unit 207.

The biggest difference between the embodiment shown in FIG. 2B includes the contact magnetic part, and the functions of the substrate 201, the IC chip 203, the wireless antenna 202, and the switch 206 are the same or similar to those of 2a.

The power supply unit 205 receives the power through the wireless antenna 202 from the wireless reader and supplies power to the contactless card or enables the driving of the IC chip as a battery. The power supply unit 205 may be included in the embodiment shown in FIG. 2A as well as the embodiment of FIG. 2B, and serves to supply power when driving power of the IC chip is required. Of course, when power supply is not required, such as when the IC chip has only a memory function, the power supply unit 205 need not be included.

Magnetic portion 207 is required for contact card use. By using the magnetic unit 207, a payment service such as payment of a small amount of public transportation can be performed through a normal contact reader.

 On the other hand, the switch 206 used in the contactless card according to the present invention illustrated in FIGS. 2A and 2B may be a mechanical switch such as a slide switch, a lock type pushbutton switch, and a toggle switch.

3 and 4A are views showing a slide switch of a non-contact card with a switch according to the third and fourth embodiments of the present invention. The slide switch shown in Figs. 3 and 4A is movable in the transverse direction and opened upon contact in one direction and shorted when contacted in the other end. The slide switch may be seated on the upper side of the card as shown in FIG. 3, or may be used by being seated on the side as shown in FIG. 4A.

On the other hand, the lock type pushbutton switch operates by changing the short circuit and the open state every time the button is pressed.

Another example of a mechanical switch is a toggle switch. A flat rectangular card cannot be used due to the thickness and size of the switch, but may be suitably used for an accessory type or a key holder type card. For example, in the case of a doll-shaped accessory card, a toggle switch may be arranged on the tail of the doll.

On the other hand, as shown in Figure 4b, a rotary switch may be used as a mechanical switch. The rotary switch is formed in a cylindrical shape, partly formed of a conductor, and partly formed of a non-conductor to maintain an open or shorted state as the switch is turned. In other words, if the portion formed of the conductor is positioned on the upper side where the wireless antenna is seated, the short circuit state is maintained and in the opposite case, the open state is maintained. In addition, as shown in Figure 4c, the rotary switch is configured in a coin shape, installed parallel to the card surface and a portion of the inner surface is formed of a conductor, the remaining portion is formed of a non-conductor, It can be maintained by changing the short and the opening according to the rotation.

 The switch included in the contactless card according to the present invention is different in that it maintains a switching state. In this way, the user can use the card according to the present invention as a contactless or contact card without operating the switch at every use.

Although the mechanical switch has been presented above, an electrical switch as shown in FIG. 5 may be used as the switch 206. In the case of a mechanical switch, it is difficult to settle on a general credit card because of the bulky size, but the electronic switch has a small volume and takes up a small space, so it is relatively easy to apply to a rectangular credit card.

Electrical pushbutton switches include flip contact switches with flip-flops or relays. 5 is a diagram of a push contact switch in accordance with the present invention. As shown, the push contact switch is turned on or off when the switch is pressed by the user, but is turned on or off by a holding circuit composed of flip-flops or relays at the rear end of the switch and capable of basic operation. Can be maintained. Therefore, even when the electric contact pushbutton switch shown in Figure 5 can be used to maintain the open and closed state of the switch. Since the conventional configuration can be taken for the holding circuit, a description of the configuration of the holding circuit is omitted here.

On the other hand, for simplicity of configuration, a contact signal of an electrical switch is input to the IC chip without including a flip-flop or a relay configuration, and the IC chip can take the configuration of controlling the non-contact transfer of data.

In this case, the IC chip may perform arithmetic functions, and a power supply unit is included to allow the IC chip to recognize whether the switch is in contact.

Fig. 6 shows an attachable switch including a conductor region inside a non-conductive switch as a switch example of another contactless card.

As shown in FIG. 6, when the switch is attached in such a way that the open antenna area covers the open antenna area, the switch is turned on so that the contactless card is usable. When the switch is removed, the switch is turned off and the contactless card is not usable. Is operated.

FIG. 7 is a view illustrating an insertable switch having one end surface formed of a conductive plate and the other end surface formed of a non-conductive plate.

The switch operates when the conductive plate is inserted in contact with the upper side on which the wireless antenna is seated, and the switch is turned off when the non-conductive plate is inserted in contact with the upper side.

As described above, embodiments of the present invention have been disclosed through the detailed description and the drawings. The terms are used only for the purpose of describing the present invention and are not used to limit the scope of the present invention as defined in the meaning or claims. For example, in the present invention, the term "card" is used. It is not only a flat rectangular card, but also includes a contactless data storage device having various forms such as an accessory form, a key holder form, a cell phone ring and a built-in watch.

Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible from this. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, the switch-integrated contactless card according to the present invention operates a switch installed in the card to selectively use a desired card from a plurality of cards stored in a bag or purse.
