Description

Destruction metal attached RFID tag {Destruction metal attached RFID tag}

The present invention relates to a destructive metal RFID tag, and more particularly, when an arbitrary detachment or detachment of a tag used to be attached to a metal flat plate or a metal rod-shaped mounting means is attempted, a primary radiator tag of wet-inlay type is attempted. Designated manager by permanently losing the function of RFID tag by damaging antenna pattern or RFID chip due to tearing of primary or secondary base sheet due to damage of damaged member installed up and down through middle and secondary radiator parasitic element. The present invention relates to a destructive metal RFID tag having a structure in which a person other than this is arbitrarily separated to prevent illegal use.

Recently, the use of the contactless card utilizing the radio frequency recognition technology is gradually increasing. Here, the radio frequency identification technology (RFID) refers to a radio frequency identification tag composed of a transponder chip and an antenna made of a semiconductor chip near a reader that emits radio waves of a specific frequency. It uses the generated current to operate the transponder chip to transmit the information stored inside the chip to the reader for communication.

The use of such radio frequency recognition technology is convenient because it does not need to be in direct contact or scanning in the visible band like a bar code, it is convenient to use, and also has a semi-permanent life advantage, the use is increasing gradually in recent years.

However, although RFID systems are used in various industries such as logistics / distribution, transportation, asset management, health care, identification, security, personal identification, defense ammunition management, waste management, anti-counterfeiting and traffic safety, However, the conventional Wet-Inlay RFID tag has a disadvantage in that the product performance is deteriorated due to the reduction of the recognition distance and the recognition rate due to the change in the reflection coefficient characteristic and the radiation pattern characteristic due to the shift of the resonance frequency according to the attachment material. -Inlay tag attached to metal cancels interference at radiating element interface by path distance of radio wave received from adjacent metal surface corresponding to ground plane, scattering phenomenon of electromagnetic wave flowing through adjacent metal surface, and electromagnetic induction to adjacent metal surface. There is a problem that the radiation efficiency drops sharply due to the transition and absorption of radio waves to the ground plane.

That is, the pattern of the Wet-Inlay tag antenna of the label type is a dipole antenna shape without a ground plane, and the radiation pattern of the dipole antenna is an omnidirectional radiation pattern radiating in both directions in free space. Therefore, if there is a medium that affects the tag radiation pattern such as metal within λ / 4 of the operating frequency on one side of the wet-inlay dipole antenna of the label type, it is necessary to Performance deterioration occurs due to offset interference, scattering of electromagnetic waves flowing through the adjacent metal surface, and transition and absorption of radio waves to the metal surface by electromagnetic induction to the adjacent metal surface.

In addition, in the case of an RFID reader antenna and a repeater antenna constituting a directional radiation pattern separately from the tag antenna, the antenna has a ground plane as a way to increase the directivity and gain of the antenna. In the case of a directional antenna having such a ground plane, the radiating element is spaced apart from the ground plane by λ / 4. The reason for this is that the energy radiated to the ground plane around the radiating element is propagated and radiated to the ground plane and is reciprocated. The reason for this is that it uses a method of radio wave synthesis of constructive interference which causes the formation of a phase such as propagation in a direction, and prevents the destructive interference of energy.

However, the tag antenna is not applicable to a structure in which the radiating element is spaced apart from the ground plane by λ / 4 as in the case of a general directional antenna. The reason for this is that RFID tags applied in field practice should be small and low cost structures.

For this reason, many metal-attached types in the form of Planar Inverted F Antenna (PIFA) of PCB structure have been used. However, PIFA-type metal tags have a disadvantage in that they are larger in size and more expensive than general label tags.

Therefore, the development of a label type wet-inlay tag that is small in volume, inexpensive, easy to mass-produce, and has no deterioration of electrical characteristics even in the vicinity of a metal is necessary for attaching to a free space or a simple dielectric.

On the other hand, the government has recently introduced a bicycle registration system as a green U-city project. This is to promote the bicycle life culture to protect the citizens' health, save energy, and enjoy a pleasant environment by activating the use of bicycles.For bicycle users, transfer to public transportation in billing through linkage with the 13.56MHz smart card applied to subways and buses It is a policy to induce more people to use bicycles through the construction of RFID system where a certain amount is discounted when the tag ID of the bicycle is recognized in the bicycle storage like a discount.

The tag required here is a metal tag, and the ID value of the metal tag is used as the registration number of the individual bike. In this case, the user who wants to see the benefits of charging with only the metal tag without using the bike. In order to prevent this, there is a need for a technique for preventing an arbitrary detachment / attachment of a tag installed on a bicycle.
