Abstract
The utility model discloses a wireless radio frequency identification e-tag becoming invalid once removed. The structure comprises a surface layer, a printed antenna, a wireless radio frequency chip, a bonding layer and a release layer, wherein the printed antenna and the wireless radio frequency chip are electrically connected and are positioned between the surface layer and the bonding layer; and the release layer is positioned on the bonding layer. When the wireless radio frequency identification e-tag is used, the release layer is peeled off at first, and then the bonding layer is bonded on an object, so as to lead the surface layer, the printed antenna and the wireless radio frequency chip to be fixed on the object. When the e-tag is removed by external force, the bonding layer is bonded on the whole or part of the printed antenna and the chip and is still bonded on the object, so that the wireless radio frequency identification function is prevented from being peeled off from the object spitefully and moved to another object for further use due to incomplete printed antenna and wireless radio frequency chip because the surface layer is removed from the surface of the wireless radio frequency identification device.
Description
Technical field
The utility model relates to a kind of radio frequency identification Electronic Tag Structure, relates in particular to a kind ofly to prevent that the function of radio frequency identification electronic tag from being shifted, and especially tool removes the structure that the radio frequency identification electronic tag was lost efficacy.
Background technology
In recent years, exploitation along with semiconductor industry progress and phase electronic technology, make and utilize radio frequency identification (Radio Frequency Identification, RFID) technology of formation radio frequency identification electronic tag (RFID Tag) is quite ripe in conjunction with electronic tag (Label/Tag), but mat is swept and is read the data that device (Reader) long distance reads electronic tag, such as password, commodity code or commodity price.The radio frequency chip (RFIC) that utilizes the sophisticated semiconductor processing procedure to be produced, the wireless radio frequency identification function and the volume that not only have the height conformability are very little.Electronic tag generally comprises the transmitter and the receiver of transceiving function, has the information storage function simultaneously, such as stored password, commodity code or commodity price.
Compare with bar code (Barcode), the radio frequency identification electronic tag has that volume provides information for a short time, active, permanance is good, the data memory capacity is big, speed is fast and safe advantage, can reaching thickness such as volume, 0.1mm, area are only arranged is 0.4mmX0.4mm, with wireless mode Auto-Sensing and reading of data, be applicable to rugged surroundings rainy, moist, carrying, reusable more than hundreds thousand of even millions of times, identification reading speed per second can reach 250 more than the label, and is not easy to be forged.Therefore be widely used in many fields, had the trend that progressively replaces bar code,, used and improve the efficiency of management, save manpower and avoid artificial error towards the trend of robotization more.
At present, the radio frequency identification electronic tag according to the different radio frequency range successful be applied to many fields, such as at low frequency (Low Frequency, LF) aspect, pet is arranged, gate inhibition's control and anti-theft tracking, at medium-high frequency (High Frequency, HF) aspect, the production control card is arranged, member card, permit identification, the aircraft air ticket, the buildings room entry/exit management, smart card and library management system, at ultrahigh frequency (Ultra High Frequency, UHF) aspect, supply chain management is arranged, aspect microwave (Mircowave), E-payment system (Electronic TollCollection is arranged, ETC) with timely positioning system (Real-Time Locating System, RTLS).
Yet, the shortcoming of above-mentioned prior art is, the radio frequency identification electronic tag is easy to be subjected to external force to peel away former article and is pasted continuation use discriminating function on another article, permit identification such as tool radio frequency identification electronic tag can be attached on another permit identification the radio frequency identification electronic tag to usurp original person's identity turnover control place by other people because of loss, or the radio frequency identification electronic tag with original producton location identification code is torn the back and changes and to be attached on the counterfeit merchandise, uses the certificate of origin of falsely using original product.
Therefore; need a kind of structure of defencive function that have to prevent that the radio frequency identification electronic tag from being falsely used; the function of the RFID devices of radio frequency identification electronic tag can't be shifted; especially has the structure that the radio frequency identification electronic tag was lost efficacy, to solve above-mentioned prior art problems.
