The present invention relates to an RFID ID card, and more particularly, by manufacturing a loop antenna for transmitting and receiving data between an RFID chip and a terminal by a printing method to reduce manufacturing costs and complete incineration so that no residue remains. In order to have environmental friendliness, the light emitting layer on which the EL sheet using EL phenomenon is installed, and the sub substrate for supplying power to the EL sheet are separately added. In this case, the front face of the EL sheet relates to an RFID ID card that can maximize the effect of the advertisement by widening the light emitting area by acting as a backlight function of the advertising surface.

In general, RFID ID cards are used to transmit and receive product information wirelessly using frequencies. They are already included in subway and bus traffic cards and are widely used in life. They are also called smart tags or smart labels. The RFID ID card has an advantage of processing information wirelessly faster than a bar code system containing information in a line-shaped image, and technology has been developed to the extent that it can immediately read product information wirelessly within a certain distance.

Such a RFID card does not need to stop and wait for the RFID card processing because the card holder handles the RFID card within the recognition distance within the antenna box of the terminal within 100ms (0.1 seconds). It can be the same size as the existing credit card or can be miniaturized, so it can be read even when the RF card is inserted in the wallet or as a jewelry. The fixed serial number is built-in, so its uniqueness and security are high, and it has excellent features such as ease of use, providing convenience to cardholders.

FIG. 1A is a structural diagram of a typical ID card, and FIG. 1B is a cross-sectional view of FIG. 1A.

That is, as shown in FIGS. 1A and 1B, a loop antenna 12 having a plurality of copper wires arranged around the top surface of the main substrate 11 is arranged, and various information is stored in the loop antenna 12. RF ID chip 13 communicating with the terminal is connected.

Upper and lower sides of the main board 11 are provided with a protective plate function for protecting the main board 11 and a protective layer 14 and 15 on which an advertisement is printed, and above the protective layer 14 and 15. The transparent films 17 and 18 which protect the advertising surface 16 printed on the surface of the protective layers 14 and 15 are arranged.

The conventional RFID ID card configured as described above receives a frequency of a high frequency band transmitted from the terminal from the loop antenna 12 when the user approaches the RFID ID card to the terminal. At this time, the operating power is induced to drive the RFID ID chip 13. As power is supplied, various information is transmitted to the terminal through the loop antenna 12 by the stored program to process the information.

As the conventional ID ID card as described above does not have a separate display device when exchanging information with the terminal, there is a problem that a user cannot confirm whether the communication is correctly performed between the ID ID card and the terminal, which may cause inconvenience to the user. In addition, there is a problem that the effect of the advertisement described because there is no separate backlight on the advertising surface (16, 17).

In order to solve the above problems, the Republic of Korea Utility Model Registration No. 0319249 (Registration Date: 2003.06.27), the light emitting diode (LED) is installed in parallel between the RF ID chip 13 and the loop antenna 12, RF It is proposed to increase the advertising effect described on the advertising surface 16 by lighting the LED with the DC power generated when the ID chip 13 and the terminal communicate with each other to have a backlight function of the advertising surface 16. .

The conventional registered utility model No. 0319249 is a light emitting diode having a backlight function is connected in parallel with the RF ID chip 13, so that when the terminal communicates with the terminal, the DC power that is induced through the loop antenna 12 is connected to the light emitting diode. Because it absorbs and consumes a certain portion, there is a problem that the malfunction occurs due to the unstable power supply to the RF ID chip 13, and there is a problem that cannot be practically applied, and the light of the light emitting diode is limited to compensate for the optical fiber. Or there is a problem that the material is required to diffuse light, such as glass fiber, the overall structure is complicated.

In addition, in all conventional ID cards, the loop antenna 12 is manufactured by winding thin copper wires several times, and attaching the copper wires to the main substrate 11 again, which is cumbersome, causing cost increases. In addition, in particular, when burned and disposed of when the end of the life of the ID ID card, all of the remaining burned incineration, the loop antenna 12, which is copper wire is not burned and remains as it is not environmentally friendly.

 The present invention is to solve the problems as described above, the EL layer (EL sheet) using the EL (electro luminescence) and the light emitting layer is installed, and operated separately from the main substrate to supply power to the EL sheet By adding the power supply layers for each, the front of the EL sheet will emit light when the RFID ID card and the terminal are in close proximity to each other, thereby maximizing the effect of the advertisement by widening the area of light by functioning as the backlight of the advertising surface. It is technical problem to do.

In addition, the present invention reduces the manufacturing cost by using a environmentally friendly material for the main substrate and the power supply layer, and by simply forming a loop antenna for transmitting and receiving data between the RFID chip and the terminal on the environmentally friendly material by printing. At the same time, the technical task is to ensure complete environmental incineration so that no residue remains.

In the present invention, a loop antenna for transmitting and receiving data between the terminal and the RFID chip is disposed on an upper surface of the main board, and a protective layer is provided on the upper and lower sides of the main board to have a predetermined strength and function as a protective plate. The other side of the protective layer is provided with a transparent film to protect the advertising surface, the loop antenna in the RFID ID card is printed and deposited using a conductive ink, the upper side of the main board when communicating with the terminal DC power supply An EL sheet power supply layer having a loop antenna for inducing organic matter and an inverter connected to the loop antenna and converting the DC power generated into AC is installed on the sub board, and the loop antenna is printed on the sub board using conductive ink. It is installed by deposition, and the upper side of the EL sheet power supply layer corresponding to the advertising surface Installation in value and is characterized in that the ELK sheet to be illuminated in the output power of the inverter is attached to the light emitting layer is installed.

Hereinafter, described in detail with reference to FIGS. 2 to 4 as follows.

Figure 2 (a) is an exploded perspective view of the RF ID card according to the present invention showing a card of a general size, Figure 2 (b) is an exploded perspective view of a small ID ID card, the upper edge of the main substrate 11 A loop antenna 12 printed at the center is arranged, and an RF ID chip 13 which stores various information and communicates with a terminal is connected at both ends of the loop antenna 12.

On the upper side of the main substrate 11, a loop antenna 23 printed around the upper surface of the sub substrate 24 is installed, and an inverter for converting DC power into AC current at both ends of the loop antenna 23 ( An EL sheet power supply layer 26 to which 25 is connected is disposed.

The light emitting layer 21 in which the EL sheet 22 is disposed is disposed above the EL sheet power supply layer 26, and has a predetermined strength on the upper side of the light emitting layer 21 and the lower side of the main substrate 11 to serve as a protective plate. The protective layers 14 and 15 on which the advertisement surface 16 is formed are provided, and above the protective layers 14 and 15, the advertisement surface printed on the surface of the protective layers 14 and 15 ( The transparent films 17 and 18 which protect the 16 are arrange | positioned.

Here, the loop antennas 12 and 23 formed on the main substrate 11 and the sub substrate 24 are formed by a printing method, and the printing material may include a conductive ink.

In other words, the conductive ink is the ink in which the conductive filler is dispersed in the vehicle, and the cured film after printing exhibits conductivity. Its main components are powder, graphite, carbon fiber and the like, and these conductive inks are widely known.

The roof antennas 12 and 23 are acrylonitrile butadiene styrene (ABS) and polypropylene, which are environmentally friendly materials, as the materials of the main substrate 11 and the sub substrate 24 used to form the printing method. (PE), polyester (PET), polypropylene (PP), paper (PAPER), vinyl chloride (PVC), nylon, polystyrene (PS).

Therefore, the main substrate 11 and the sub-substrate 24 are formed by printing the loop antennas 12 and 23 so that the main substrate 11 and the sub-substrate 24 and the main substrate 11 and the sub-substrate 24 may be used during incineration. The roof antennas 12 and 23 are completely incinerated so that no residue remains.

The EL sheet 22 applies a phosphor to be a light emitting layer on a transparent organic film or a linear structure, and when an alternating voltage is applied, the electric field causes the phosphor to quickly charge and discharge, and the movement of electrons in this cycle It uses EL (electro luminescence) phenomenon, which is seen as light, and forms a light emitting layer by sequentially forming a fluorescent layer and an insulating layer between the transparent conductive film film and the back electrode, and the insulating layer and the back electrode to protect the light emitting sheet. It is a planar surface light-emitting body which consists of a structure which inserted the carbon protective film in between.

In this EL sheet 22, when an alternating voltage is applied to a light emitting layer composed of phosphors, electrons are accelerated by high electric field portions in the phosphors, and excited energy is generated (excitation) in which high energy electrons are generated. Since it is obtained every time it changes, it emits twice in one cycle when AC voltage is applied.

That is, when the voltage flows between the transparent electrode and the back electrode and exceeds the threshold voltage, electrons existing at one interface between the insulator and the phosphor are tunneled into the phosphor, thereby obtaining a large kinetic energy from an electric field inside the phosphor. .

These high energy electrons collide with light emitting atoms injected into the phosphor to excite the electrons of the light emitting atoms, and the excited electrons fall back to a low level to generate light. After the collision, the electrons are trapped at the other interface, and when a signal of opposite polarity is applied, electrons already trapped at the interface are tunneled back into the phosphor to generate light.

Such EL sheet 22 is a solid plane light emitting body by electric field, which does not generate heat at all, and can be installed in contact with any object such as glass surface, acrylic, etc. Is unnecessary, and the operational power consumption is very small.

In addition, since it is light and ultra-thin, it is easy to select subsidiary materials and is strong against impact and pressure, so it can be installed on the inside of car, stage floor, and high place. It can express beautiful light with abundant color without eye fatigue than FLEX which relies on, and there is no environmental pollutant such as mercury such as neon and fluorescent lamp inside Panaplex, which is environmentally friendly.

According to the present invention configured as described above, first, when the user approaches the RF ID card of the present invention to the terminal, the resonance frequency of the high frequency band transmitted from the terminal is received by the loop antenna 12, and at this time, the operating power is induced and the RF is lost. As the driving power is supplied to the ID chip 13, various kinds of information are transmitted to the terminal through the loop antenna 12 to process the information by the stored program.

At the same time, when the user approaches the RF ID card of the present invention to the terminal, the resonance frequency of the high frequency band transmitted from the terminal is screen-printed as a conductive ink on the sub substrate 24 of the EL sheet power supply layer 26. In this case, about DC power is induced, and the DC power is converted into AC as supplied to the inverter 25 and then applied to the EL sheet 22 installed in the light emitting layer 21 to emit light.

The inverter 25 is a device for providing a current to the EL sheet 22, and converts DC (direct current) to AC (AC), so that the light emitting device of the EL sheet 22 can stably emit light. In particular, by adjusting the voltage and frequency within the operating range of the inverter 25, it is possible to change a variety of brightness, flashing method, speed, etc.

As such, when the EL sheet 22 emits light, the advertisement surface 16 on the protective layer 14 is illuminated from the rear to maximize the effect of the advertisement, and in particular, by each of the loop antennas 12 and 23. Independent power supply to the RF ID chip 13 and the EL sheet 22 does not affect each other's operation at all, thus making stable operation, and utilizing the entire surface of the protective layer 14 as an advertising surface and emitting layer If all 21 is composed of EL sheet, the effect of advertisement can be increased even more.

In addition, the loop antennas 12 and 23 formed on the main substrate 11 and the sub substrate 24 made of environmentally friendly materials are deposited by a printing method, so that no residue remains during incineration, thereby being environmentally friendly.

As described above, the present invention manufactures a loop antenna for transmitting and receiving data between an RFID chip and a terminal by a printing method, thereby reducing manufacturing costs and making an incineration process so that environmentally friendly materials do not remain. The EL sheet is operated separately from the main board, and the sub-board for supplying power to the EL sheet is added.
