Description
Technical Field
The invention relates to the field of electronic tags, in particular to an ultrahigh frequency RFID (radio frequency identification) anti-tearing tag.
Background
With the falling of concepts such as smart cities and new retailing, unmanned retail schemes based on RFID technology are widely used. According to the scheme, the commodity and the label are bound, and the selling condition of the commodity is judged by reading the label information of the residual commodity in the retail cabinet, so that the retail intellectualization is realized.
The binding mode of the commodity and the label is that the label is generally attached to the surface of the commodity, if a customer tears the label and places the torn label in a commodity selling area, the RFID card reader can still read the label information, so that the commodity is likely to be free, and the loss of a merchant is likely to be caused; the label has the characteristic of tearing resistance, so that the damage of goods can be greatly reduced, the conventional tearing-resistant label is made into a fragile form, and the technical scheme of the fragile label is that conductive ink or metal particles are printed on fragile paper materials and PET (polyethylene terephthalate) base materials through silk screens to form a printed RFID antenna, or the transparent PET is firstly made into a transferable fragile antenna, then chip binding is carried out, then the transferable fragile antenna is compounded with self-adhesive, and then adhesive backing is carried out; the frangible labels of any technical scheme have a cost which is greatly higher than that of the common labels, so that the cost of merchants is greatly increased, and whether the frangible labels can be read again after being shredded depends on broken lines, so that the frangible labels have great randomness and the tearing-proof effect cannot be ensured.
In addition, due to various goods, the performance of the labels is required to be guaranteed to be good enough when the labels are attached to all the goods, the existing labels are too large in size, the labels are not easy to attach to some goods, or are good in performance when attached to metal packages, and poor in performance when attached to nonmetal packages, and general electronic labels do not have good compatibility.
