Abstract
The invention provides a non-contact type electronic tag with anti-false and anti-transfer function and a preparation method thereof, wherein the electronic tag consists of a support layer, a functional high polymer material coating, an antenna and a chip; the functional high polymer material coating is compounded on one side of the support layer; the antenna is fixed on the other side of the functional high polymer material coating; the chip is bonded on the antenna; and the functional high polymer material coating comprises the following compounds in percentages by weight: 5-90% of light solidified type resin, 1-5% of light trigger and 9-94% of connection resin. The electronic tag is attached on goods or the surface of the outer package of goods; when the label of RFID (Radio Frequency Identification Devices) needs to be peeled, the material on the surface of the support layer is capable of being peeled easily, while the parts of the RFID chip and the antenna are still glued on the surface of the package of goods and have the performance of frangibility so as to be incapable of being peeled completely; and the antenna of the RFID is damaged when peeling to lose reading and writing functions so that the effect of safe guard against falsification is achieved.
Description
Technical field
The present invention relates to a kind of Lontactless electronic tag with anti-transfer function and preparation method thereof.
Background technology
Radio frequency identification (being called for short RFID) technology is identified destination object automatically and is obtained related data by radiofrequency signal, and identification work need not artificial interference, can work in various environment, can identify a plurality of labels simultaneously, and is swift and convenient to operate.After 2004, the RFID technology obtains vigorous growth, and potentiality have a wide range of applications in fields such as warehouse logistics, product false proof, products in circulation and product maintenance trackings.In the application of product false proof, RFID with its safety, efficient, quick, storage volume is big, store information change waits characteristics to be called as " the electronics patron saint " of a new generation freely.
Simultaneously, radio RF recognition technology is because the UID sign indicating number whole world of its chip is unique, information stability, counterfeit cost is high, can store bulk information, and can simply read and write, special-purpose recognition device that the consumer provides by the businessman identity of recognition value easily can be made, and the all-the-way tracking in the circulation of commodities can be used for realizing.
It is that base material is produced that RFID label in the market adopts paper or mylar more, especially at present the aluminium etch pattern RFID label that is widely used, restriction in view of its aluminium etch process and chip binding technology, prepared RFID label and base material tight bond, the stability of good processing and use is provided, but it has also limited it at commodity circulation, especially the application in commodity counterfeit prevention field.The lawless person can not destroy its physical arrangement with complete the peeling off of RFID label on the genuine piece commodity by the certain physics chemical means, label still can be read, it is affixed on the counterfeit goods again, just is difficult to distinguish with genuine piece, just lost its meaning as false proof and logistics management.
