Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip processing product having both an RFID shielding function and an RFID activation function,

The present invention relates to an idea of a product that operates to selectively activate RFID (Radio Frequency Identification) region frequency generation, and related products, and includes RFID (Radio Frequency Identification) technology, induction magnetic field generation and shielding technology .

This technology is designed to physically distinguish between RFID activation and deactivation in the current society in which various services and products using RFID are emerging, This course deals with the design and manufacture of application products. In addition, smart phones equipped with hardware and control software related to NFC (Near Field Communication) are becoming common, and the Internet of things is popularized and various services and products for social development are appearing. The present invention relates to a product having both a magnetic induction current suppressing region for shielding an RFID operating through a magnetic induction current and an active region capable of activating the RFID on the opposite side, .

NFC technology is related to the RFID patent (Charles A. Walton "Portable radio frequency emitting identifier" US Patent 4,384,288 issue date May 17, 1983.) designed by Charles Walton in 1983, It is based on the Near Field Communication (NFC) Forum.

When a smartphone or NFC reader with NFC function is approached, the magnetic field again induces the current in the NFC antenna of the smartphone / NFC reader and reads the induced current to enable communication. However, when the metal is near, the inductance of the coil is reduced and the eddy current is induced, so that the performance of the NFC is drastically reduced.

Also, materials with high resistivity and high magnetic permeability (typically soft magnetic ferrite materials) allow the magnetic field to avoid this performance degradation of the metal. That is, the magnetic field is transmitted only in the ferrite material, and the high resistance of the ferrite prevents the generation of the eddy current, so that the magnetic field in the opposite direction is not generated and the NFC communication is not interrupted.

Therefore, it is possible to inactivate the RFID function by inducing a decrease in the performance of the RFID antenna induced current by the direction of the metal surface, and by installing a magnetic sheet having a high magnetic permeability between the NFC antenna and the metal surface, The NFC chip can be operated normally. That is, the RFID / NFC shielding state can be maintained on one side and the RFID / NFC active state can be maintained on the other side, thereby selectively shielding and activating the plurality of RFID / NFCs.

Various kinds of services and products are becoming more and more common as the Internet of Things technology connects the Internet with a structure capable of acquiring sensors and data on objects. The 'Internet of Things' most commonly used in everyday life is the 'transportation card', which corresponds to NFC among RFID. With the availability of NFC capabilities in most smartphones, the types and sizes of services and products that leverage NFC are expanding. That is, it is becoming increasingly common to own more than one RFID product, and many cases of carrying multiple NFC products are becoming common.

When another RFID card such as a transportation card or a smart ID card is put in a wallet, it is difficult for the reader to recognize multiple RFID chips or malfunctions. However, it is possible to have selectivity for the use of multiple RFID / NFC products through a product that can maintain each state of 'RFID / NFC Shielding and Active' on each side.

In addition to designing and manufacturing chip processed products with RFID / NFC shielding and active features, we have devised methods and techniques for manufacturing NFC application products in the 'fashion and sundry' market, which can be produced using chip processed products .

The present invention provides solutions to solve the problems that conventional RFID / NFC products do not operate properly while mutually interfering with each other. In addition, the value of the idea of designing a new product by fusing related technology and conventional products is recognized.

According to the present invention, a desired product can be selectively used or shielded while having a plurality of RFID / NFC products by eliminating mutual interference between RFID / NFC products. Through this, there is an industrial effect that can reduce the problem of short distance communication and accommodate a wider range of services and products in the Internet of things.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional view of an RFID / NFC shielding containing an NFC chip and a chip product having an active function. The NFC tag is composed of a chip 100 including an integrated circuit such as a memory and a CPU, and an antenna 101 for generating an induced current to write to the chip or transmit information of the chip to the reader. Chips are sensitive to shocks and static electricity, and because antennas are usually deposited on thin plates by corrosion, they are susceptible to physical and electrical stimuli from the outside. In order to protect it, a shock-absorbing material is laminated with an insulating material (110), and a ferrite sheet or an insulating material (120) is laminated on the metal surface to maintain and protect the hardness and shape. A ferrite sheet 150 is embedded under the inner surface 101 of the outer surface protective material 110 so as to ensure induction current generation of the antenna 101.

It is usually used when a chip product is seated on metal, but it can be used for fashion accessories such as wallets. This is chosen according to the requirements of the manufacturer.

2 is a cross-sectional view of a chip product including an RFID / NFC shield and a metal material having an active function. 1 except that a metal material 130 is inserted between the ferrite sheet 150 and the protective outer material 120. In the case of inserting the metal material 130, the shielding effect is enhanced, and the metal material 130 to be selected is determined according to the physical characteristics of the product desired by the product manufacturer.

FIG. 3 is a plan view of a square chip product having RFID / NFC shielding and an active function, wherein the chip product 210 configured as shown in FIG. 1 or FIG. 2 has a rectangular shape.

FIG. 4 is a plan view of a circular shaped chip product having RFID / NFC shielding and an active function, wherein the chip product 210 having a shape as shown in FIG. 1 or FIG. 2 has a round shape.

FIG. 5 shows a configuration in which a chip product 210 is transplanted into a business card holder as an example to make an electronic business card.

The NFC tag has an operating mechanism for activating the chip 100 by generating an induced current in the antenna 101 by a magnetic field change occurring in the reader and writing the data to the memory inside the chip or to transmit the data written in the memory to the reader. Therefore, since the metal material 130 shields such a magnetic field change, the induction current can not be generated and the chip is not started. In order to be usable on the metal material 130, a ferrite material plate 150 is attached under the plate on which the antenna is deposited. Thus, a plurality of RFID / NFC functions can be selectively activated by attaching the shielded chip product (FIG. 1) to an outer surface of a metal material or by embedding the same in an application such as a shielding card or a wallet.

(FIG. 2) containing a shielding chip product (FIG. 2) including a metal material 130 to shield other RFID / NFC products and activate the RFID / NFC function of the chip processed product.

That is, there is a method of generating the chip product 210 in correspondence with various types and materials, and there is originality about the idea of manufacturing a new product called a smart business card holder by adding an electronic business card function to a general business card holder and a manufacturing method.
