Those skilled in the art should understand that the present application can also be implemented without some specific details. In some examples, methods, means, elements and circuits well known to those skilled in the art are not described in detail, in order to highlight the main ideas of the present application.
[0028] As shown in Figure 1 , Figure 2 and Figure 3 The radio frequency identification electronic tag of the embodiment of the present application comprises a substrate 200, two antennas 100, two adhesives 400, a chip 600 and a bridge point 500. The substrate 200 is a paper material. The two antennas 100 are respectively arranged on the front and back surfaces of the substrate 200. One side of the adhesive 400 is pasted to the bottom side of one of the antennas 100, and the other side is pasted with a release paper 300. The two adhesives 400 are respectively located at the two ends of the bottom side of the antenna 100, and are separated by a predetermined distance. The chip 600 is connected to one of the antennas 100, and the bridge point 500 connects the two antennas 100.
[0029] In this embodiment, by using paper material as the substrate 200, the front and back surfaces are coated with glue, and the back surface is covered with adhesive 400 to provide the adhesive force of the glue after coating and the article, which is convenient for sticking to other objects. The center position of the radio frequency identification electronic tag front and back surface is bonded to the article, and when maliciously removed, the center position of the bridge point 500 is easy to damage. Specifically, two adhesives 400 are respectively arranged on one side of an antenna 100, and the two adhesives 400 are spaced apart by a predetermined space, and liquid glue with strong bonding ability can be coated between the two adhesives 400. If you want to maliciously remove it, the antenna 100 will be damaged due to the strong bonding ability of the liquid glue, preventing the electronic tag from being maliciously reused.
[0030] In a specific embodiment, the adhesive 400 has a predetermined thickness, which facilitates the coating of liquid glue between the two adhesives 400. When coating the liquid glue, the adhesive 400 has a thickness, so a certain amount of liquid glue can be coated between the two adhesives 400 to make the adhesion between the release paper 300 and the antenna 100 more secure. When maliciously removed, the antenna 100 will be damaged to prevent the electronic tag from being maliciously reused.
[0031] In a specific embodiment, the bridge point 500 is two, one bridge point 500 is located at the center position of the substrate 200 and connected with one antenna 100, and the other bridge point 500 is located at the edge position of the substrate 200 and connected with the other antenna 100, connecting the two antennas 100. The bridge point 500 is used to connect the two antennas 100 located on the front and back of the substrate 200, ensuring that the electrical signal between the antennas 100 can be smoothly transmitted, so that the tag can normally receive and transmit radio frequency signals, completing information reading and transmission. One bridge point 500 is located at the center position of the substrate 200, and the other edge bridge point 500 is located at the edge position of the substrate 200.
[0032] Further, in this specific embodiment, at least one bridge point 500 is located between the two adhesives 400. After coating liquid glue between the two adhesives 400, the bridge point 500 and the antenna 100 can be fixed. Once damaged, the bridge point 500 and the antenna 100 will be damaged, avoiding malicious use.
[0033] In a specific embodiment, the antenna 100 is arranged in a ring structure, and the antenna 100 extends towards the middle position with an anti-shift part to prevent the antenna 100 from loosening during use.
[0034] Further, in this specific embodiment, the cross section of the anti-shift part is square, which has good fixation after being pasted with the substrate 200, and the anti-shift part is multiple and is arranged along the circumference of the antenna 100, further improving the fixation stability of the antenna 100 and the substrate 200.
[0035] In a specific embodiment, the end of the antenna 100 passes between two adhesives 400, and the end of the antenna 100 and the bridge point 500 are fixed by the liquid adhesive, and can be damaged when the device is removed.
[0036] Embodiments of the application have been described above, with the understanding that these embodiments are exemplary only and are not exhaustive of all embodiments of the application. Many modifications and variations of the described embodiments are possible in light of the above teachings. It is therefore to be understood that within the scope of the claims and their equivalents, many variations of this application can be constructed. The selection of words used in this document is intended to best explain the principles of the embodiments, the practical application, or the improvement over the technology in the art, or to enable other ordinary skilled in the art to understand the embodiments disclosed herein.
