In addition, the above-mentioned pre-registration proposals can use only a traffic card in the form of a card, there is a problem that can not be applied to a traffic card (for example, Figs. 3a to 3c) other than the card form.

An object of the present invention is to solve the conventional problems as described above, in particular, by forming the barrier layer and the adhesive layer on the sheet to adhere the sheet to the traffic card to use, first, through the barrier layer Prevents the payment of the transportation card by blocking the exchange of data or the generation of induced electromotive force between the transportation card and the transportation card terminal, and secondly, "Traffic card multi-recognition prevention to facilitate the removal of the sheet to the transportation card by the adhesive layer Sheet and method ".

That is, the barrier layer and the protective paper are sequentially formed on one side of the sheet to prevent the exchange of data and the generation of induced electromotive force between the transportation card terminal and the transportation card, and the adhesive layer and the release paper are sequentially formed on the other side of the sheet to facilitate the transportation card. It is to be detached.

In order to achieve the above object, the present invention "traffic card multiple recognition prevention sheet",

Such release paper is used to prevent foreign matter from adhering by the adhesive force of the adhesive layer in the manufacture, packaging, transportation and use of the product, and is used by removing it.

The adhesive layer is formed on the blocking layer, or is formed on the opposite side to the blocking layer is formed.

That is, the barrier layer and the adhesive layer may be sequentially formed on the sheet, or the barrier layer may be formed on one surface and the adhesive layer may be formed on the other surface with the sheet interposed therebetween.

In the above, it is preferable to form a blocking layer on one surface of the sheet and to form an adhesive layer on the opposite surface.

The barrier layer is formed on the entire surface of the sheet or a portion of the sheet.

When the blocking layer is formed, the roof antenna is formed on the seat at the corresponding position so that the entire roof antenna or a part of the roof antenna is covered along the roof antenna installation position mounted on the traffic card.

This will be described as follows.

As is well known, a traffic card generates power through a loop antenna to be used as an operating power source for a traffic card chip, and communicates with a traffic card terminal by a frequency induction phenomenon using an impedance change.

Therefore, when the blocking layer is formed on the sheet to cover all or part of the loop antenna, the generation of induced electromotive force is prevented by the blocking layer, and no power is generated, or the generated power is weak, so that communication with the traffic card terminal is weak. Of course, the impedance is changed by the blocking layer so that communication with the traffic card terminal is not performed.

At this time, the thickness, length and shape of the barrier layer is appropriately selected according to the type of traffic card.

The easiest method is to form a blocking layer on the sheet so that all the loop antennas inherent in the transportation card are wrapped, but in this case, the blocking layer may interfere with payment of other adjacent transportation cards.

Therefore, if the thickness, length and shape of the barrier layer is adjusted so that only the transportation card with the seat according to the present invention is not accepted, only the transportation card with the seat according to the present invention without disturbing the payment of the other transportation card. It can be configured not to make payment.

The barrier layer is characterized by being composed of a conductive material such as gold, silver, copper, aluminum, conductive powder, conductive paint, or the like.

That is, a metal thin film made of a conductive material such as gold, silver, copper, and aluminum is adhered onto the sheet to form a blocking layer, or a conductive powder is applied to form a blocking layer, or a conductive paint is printed to form a blocking layer. .

The barrier layer is formed on the sheet corresponding to the roof antenna installation position by using the conductive material, the conductive powder, or the conductive paint. The main purpose is to.

The barrier layer is characterized in that it is configured to have a constant reactance value using a conductive material such as gold, silver, copper, aluminum, conductive powder, or conductive paint.

The barrier layer is intended to prevent data exchange between the traffic card and the traffic card terminal by having a constant reactance value using the conductive material, the conductive powder, or the conductive paint.

For example, if the copper or aluminum thin film is designed to have a constant reactance value and then adheres to the sheet along the loop antenna of the transit card, the reactance value of the transit card loop antenna is changed by the reactance value so that the transit card and the transit card Data exchange (communication) can be prevented.

The "constant resonant frequency value" refers to a frequency value that interrupts data exchange (communication) between a traffic card and a traffic card terminal by changing the communication frequency of the traffic card due to frequency induction.

It is well known that the reactance value of the traffic card loop antenna is changed by the reactance value of the blocking layer, or the frequency induction phenomenon in which the frequency of the traffic card loop antenna is changed by the resonance frequency of the blocking layer is well known. Omit.

The sheet is characterized in that it is made of a tacky material having a moderate adhesive force.

The sheet is made of a silicone, natural rubber, or urethane-based material having a suitable viscosity, such that it is possible to detachable to the traffic card without using a separate adhesive layer.

For example, if the sheet is configured by adjusting the viscosity of silicon, the sheet made of silicon can be directly attached to the traffic card without a separate adhesive layer. In addition, in the case of such a sheet, if the adhesive force is reduced due to continuous use, the adhesive force can be reduced by removing (washing) the foreign matter of the sheet, thereby enabling repeated use.

The sheet is composed of a front sheet and a back sheet adhered to the back of the transportation card integrally formed on the front of the traffic card, and forming a barrier layer on each of the front sheet and the back sheet, and then the front sheet and the back sheet Fold and characterized in that it is configured to stick to the front and back of the traffic card.

Hereinafter, the technical idea of the present invention "traffic card multiple recognition prevention sheet" will be described in detail.

In the description, the same or similar names and symbols are used for components having the same or similar components and functions.

Example 1

In Example 1, a barrier layer is formed on one surface of the sheet, an adhesive layer is formed on the other surface, and a protective paper is formed on the barrier layer, and a release paper is formed below the adhesive layer.

In addition, in the first embodiment, the technical idea of preventing payment of a transportation card by preventing the generation of induced electromotive force of the transportation card by the blocking layer will be described as an example, and the transportation card will be described as an example. .

The reason why the first embodiment is constructed as described above is that other embodiments according to the technical idea of the present invention can be easily understood from the first embodiment.

Hereinafter, the configuration of the first embodiment will be described.

First, as shown in FIG. 1, the barrier layer 120 and the protective paper 110 are sequentially formed on the upper surface of the sheet 130 having the same size as the traffic card 10, and the adhesive layer ( 140 is formed, and the release paper 150 is attached to the bottom of the adhesive layer 140 to constitute the first embodiment.

The blocking layer 120 is configured in the form of a rectangular ring having a predetermined width along the installation position of the loop antenna 12, the aluminum foil, and the protective paper 110 is configured by bonding or coating a transparent or opaque material. .

The adhesive layer 140 is formed by applying an adhesive material on the lower surface of the sheet 130, the release paper 150 is preferably configured using a transparent vinyl.

Hereinafter, the operation and the effect of the first embodiment will be described.

As is well known, a traffic card generates an induction electromotive force by a traffic card antenna by using a high frequency (or magnetic field) generated from a traffic card terminal, and supplies power to the traffic card chip with the generated induction electromotive force. Payment is performed by performing communication.

Therefore, when the blocking layer 120 is formed so that the loop antenna 12 of the traffic card 10 is blocked as in the first embodiment, the high frequency transmission (or magnetic force transmission) between the traffic card and the traffic card terminal is interrupted. Interfering with the generation of the induced electromotive force of the loop antenna 12, thereby preventing the operation of the traffic card chip 13, the traffic card 10 is not paid.

This is because the radio waves do not pass through the conductive material and the magnetic field is absorbed by the conductive material, and the traffic card loop antenna is caused by the electromagnetic wave (high frequency) or magnetic field generated by the traffic card terminal due to the blocking layer 120. The generation of induced electromotive force of the transit card will not work, thereby preventing payment.

That is, in the case of a traffic card and a traffic card terminal using radio waves (high frequency), the radio wave (or magnetic field) is prevented from reaching the loop antenna 12 of the traffic card 10 by the blocking layer 120, thereby inducing Since the generation of electromotive force is prevented, the generation of the operating power of the transportation card chip is prevented and payment is not made.

FIG. 7A shows a rectangular ring-shaped blocking layer 120a formed so as to completely cover the traffic card loop antenna 12 on the sheet 130a of a traffic card size, and FIG. 7B shows a portion of the loop antenna 12. FIG. 7C is a view illustrating the formation of the blocking layer 120b so that only the roof antenna 12 is covered on the sheet 130b having the cavity formed therein. FIG. 7D illustrates that the blocking layer 120b is formed so that only a part of the loop antenna 12 is covered.

FIG. 8D is a view showing the configuration of 120c, and FIG. 8D is a diagram showing a line-like blocking layer 120d and a sheet 130d configured to cover only a part of the loop antenna 12. As shown in FIG.

FIG. 9A shows the blocking layer 120e formed on the entire sheet 130a, and FIG. 9B shows the blocking layer 120f formed on a part of the sheet. FIG. 9C shows only a part of the loop antenna 12. FIG. In the formation of the blocking layer 120f, the size of the sheet 130d is similar to that of the blocking layer 120f.

In addition, Figure 10a is a view showing a blocking layer (120g) is formed on the front surface of the sheet 130e having a circular shape to be applied to a traffic card having a circular shape, Figure 10b is blocked so that only a part of the loop antenna is blocked. FIG. 10C is a view showing the formation of the layer 120h, and FIG. 10C is a view showing the formation of the sheet 130f and the blocking layer 120i to have a cavity therein, and FIG. 10D shows only a part of the loop antenna formed in a circular shape. It is a figure which shows the sheet 130g and the blocking layer j formed so that it may lose weight.

In the structure of the sheet and the blocking layer, the blocking layer (Figs. 7B, 7D, 8B, 8D, 9B, 9C, 10B, and 10D) formed to cover only a part of the loop antenna is used as a traffic card loop antenna. Instead of completely preventing the generation of induced electromotive force of the to prevent the payment of the transportation card by ensuring that only a portion of it is not supplied enough power to operate the transportation card.

In other words, in forming the blocking layer, by forming the blocking layer so that only a part of the loop antenna is covered, sufficient power cannot be formed, and as a result, payment of the transportation card is prevented.

In this case, when configuring the blocking layer, by adjusting the reactance value to prevent communication between the traffic card and the traffic card terminal, the communication prevention effect is added to the payment prevention effect by the induced electromotive force generation prevention to prevent payment of the traffic card. It can also be configured.

FIG. 16 is a view showing a method of attaching and using a sheet 130a configured in Example 1 to a traffic card 10. In the case of not using a traffic card, FIG. By adhering the sheet to the transportation card, the payment of the transportation card is prevented, and when the transportation card is to be used again, the transportation card is settled by removing the sheet from the transportation card.

As described above, the first embodiment is configured to suppress the induced electromotive force generation of the traffic card loop antenna, and as described above, the payment of the transportation card is prevented by preventing or preventing the generation of the induced electromotive force through the traffic card loop antenna. Will be prevented.

Example 2

The second embodiment will be described by exemplifying what constitutes the technical idea of the present invention using a sheet made of an adhesive material.

In addition, in the second embodiment, the technical concept of preventing transportation card payment by preventing data exchange (communication) between the traffic card and the traffic card terminal by the blocking layer will be described as an example. This will be described as an example.

The reason why the second embodiment is configured as described above is that other embodiments according to the technical idea of the present invention can be easily understood from the second embodiment.

In the description of the second embodiment, a description of the duplicated matters of the first embodiment will be omitted.

Hereinafter, the configuration of the second embodiment will be described.

First, as shown in FIG. 11, after the sheet 131 is made of an adhesive material such as silicone, urethane, or natural rubber, the blocking layer 121 and the protective paper 110 are sequentially formed on the upper surface of the sheet 131. Then, the release paper 150 is attached to the lower surface of the sheet 131 to constitute the second embodiment.

The blocking layer 121 is configured to have a constant reactance value by using a conductive material, conductive powder, or conductive paint.

Hereinafter, the operation and the effect of the second embodiment will be described.

As is well known, the data transmission method of a traffic card made of a passive RFID tag uses a backscatter modulation method, and changes the load impedance (mainly reactance) of the loop antenna in order to efficiently backscatter the total reflection of radio waves by impedance mismatch. Induce.

That is, when the load impedance (reactance) value is changed through the switching transistor or the switching diode, the loop antenna is short-circuited to increase the current of the loop antenna, which causes backscattering of the received carrier wave.

Therefore, when the blocking layer 131 has a constant reactance value, it prevents the backscattering of the traffic card loop antenna and thus interferes with the communication between the traffic card and the traffic card terminal, thereby preventing payment.

That is, as shown in FIGS. 7 to 10, when the blocking layer is formed so that all or part of the traffic card loop antenna is covered according to the shape of the traffic card, the blocking layer has a constant reactance value. By changing the reactance value of the antenna, payment is not made.

12 and 13 illustrate another configuration of preventing payment of a transportation card by interrupting data exchange (communication) between the transportation card and the transportation card terminal. The blocking layers 121a and 121b have a constant reactance value. After the formation, the resonant circuit component 160 is connected to the blocking layers 121a and 121b to form a constant resonant frequency so that payment of the traffic card is not made by the frequency introduction phenomenon.

That is, at least one capacitance element (capacitor), reactance element (coil), or resistance element (resistance) is connected to the blocking layers 121a and 121b in series, in parallel, or in parallel with the blocking layers 121a, 121b) together with a constant resonant frequency to change the frequency of the traffic card by the frequency phenomena so that the payment of the transportation card is not made.

For example, in the case of a traffic card, a frequency of 13.56 MHz is used. When the blocking layer and the resonant circuit component 160 are configured to have a resonant frequency of 14.5 MHz, the frequency of 13.56 MHz is 14.5 by the resonant frequency. It is changed to the frequency of MHz to prevent communication between the traffic card and the traffic card terminal.

FIG. 14 is a circuit diagram showing an example in which the blocking layers 121a and 121b (L) having a reactance value and the capacitor C are configured to have a constant resonance frequency.

The capacitor (C) is preferably configured by printing on a sheet using a conductive material.

Frequency induction, coupling degree, Q value, and the like, which change adjacent resonance frequencies are well known, and thus detailed description thereof is omitted.

According to the second embodiment configured as described above, the blocking layer has a constant reactance component, and then the payment of the transportation card is prevented by preventing data exchange (communication) between the transportation card and the transportation card terminal using the reactance component. .

In addition, the sheet according to the second embodiment can be easily detached to the traffic card without a separate adhesive layer by configuring the sheet itself with a tacky material.

As described above, the first and second embodiments of the present invention form a blocking layer so that all or part of the traffic card loop antenna is covered with a conductive material, and in some cases, the blocking layer has a constant reactance value. By preventing the generation of induced electromotive force of the card or by preventing data exchange between the traffic card and the traffic card terminal, there is an effect of preventing the payment of the traffic card.

In addition, the sheet is composed of an adhesive material, or by using an adhesive layer to have a sheet adhesive force is a very useful invention that can be easily removed and used on the traffic card.

However, in the above embodiments, the blocking layer is formed to cover only one surface of the traffic card as an example, but the technical spirit of the present invention is not limited thereto.

That is, as shown in Fig. 15, in forming the seat 130h according to the present invention, the front sheet 130h1 sticking to the front of the traffic card and the back sheet 130h2 sticking to the back of the traffic card are integrally formed. After the barrier layers 120a1 and 120a2 are formed on the front sheet 130h1 and the back sheet 1302, the front sheet 130h1 and the back sheet 130h2 are folded and adhered to the front and back of the traffic card. Note that it can be configured as possible.

In the figure, reference numeral 131 denotes a folding line.

FIG. 17 is a view showing a state in which a sheet 130h according to the technical concept of the present invention consisting of a front sheet 130h1 and a back sheet 103h2 is attached to a transportation card back and forth, and FIG. An example of configuring the front sheet 130b1 and the back sheet 130b2 is shown.

In addition, in the above embodiments, the technical idea of the present invention has been described as an example of applying the square card of the present invention, but the technical idea of the present invention is not limited thereto.
