Description
Technical field
The utility model belongs to RFID (radio frequency identification) label technique field, in particular to a kind of anti-fake radio frequency identification of tamper-evident
Label.
Background technique
With the development of technology of Internet of things, the application as the important component part RFID label tag in one, the field is increasingly
It is universal, especially a kind of trend is increasingly becoming using the anti-fake RFID label tag of tamper-evident in terms of commodity counterfeit prevention, new retail.
Currently used RFID label tag tamper-evident method for anti-counterfeit usually has 2 kinds:
The first: the Inlay of the RFID antenna production after etching being transferred in artificial synthesized fragile paper and realizes tamper-evident
Effect, disadvantage are as follows:
1, the production technology of fragile paper is complicated, at high cost；
2, it needs for label antenna to be transferred in fragile paper, not only process is more, but also is easy breakage, the yield rate of label
It is low；
3, fragile paper in cross cutting can not waste discharge, be unable to rewinding, can only cut, machine automatic labeling cannot be used, influence to paste
Target efficiency；
4, frangible paper size is influenced by humidity, poor dimensional stability, easily causes the electrical property of material breaks or antenna
It can change；
5, the weatherability of fragile paper is poor, in freezing and refrigeration, moist environment has limitation, in addition in the transport week of commodity
It is easily damaged during turning；
6, when the gum of label is thicker, tensile strength is relatively high, when doing gum such as double-sided adhesive, even fragile paper mark
Label still have the possibility completely taken off again.
(2) substrate that material does label antenna is opened using special being layered, the label of this method production is from affixed object
On when opening upper layer substrate be stripped, lower layer's substrate, antenna and chip can stay on affixed object, and such tamper-evident antifalsification label is not
Foot is as follows:
1, it can be divided into and open the at high cost of material；
2, it needs to shift label antenna and chip into past, technique from PET (polyethylene terephthalate) substrate
It is more；
3, this part stayed on affixed object cannot be avoided completely to be taken off the possibility of reuse completely.
In short, above two label is all using continuous gluing as gum, especially gum is thicker, glue film is tough
Or use double-sided adhesive as gum in the case where, the glue film of gum plays apparent reinforcing effect to label antenna, improves quilt
Probability again is completely stripped, in addition, cost is higher.
