[0002] Radio frequency identification (RFID) electronic tags are widely used in the fields of commodity anti-counterfeiting and traceability, such as drug packaging, anti-counterfeiting labels for high-value commodities, etc.

[0003] However, when using an electronic tag on the surface of a metal, the shielding effect of the metal on the radio frequency signal causes the communication distance of the electronic tag to be significantly reduced, and it may even not be recognized by the reader. The anti-metal electronic tag can significantly reduce the interference of the metal on the radio frequency signal and maintain the reading performance of the tag. The anti-metal electronic tag provides good reading performance through the characteristics of its anti-metal material, but at the same time, there is also the problem that it is easy to be completely removed, which may lead to the improper recycling and malicious reuse of the electronic tag.

[0004] When the anti-metal electronic tag is completely torn off from the surface of the commodity and reused, it is extremely easy to cause the problem of the circulation of counterfeit commodities. Therefore, how to provide an effective way to prevent the electronic tag from being reused after being transferred has become an urgent problem to be solved. Summary of the Utility Model

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0017] First, briefly describe the technical solution of the present utility model, as Figures 1 to 3As shown in the figure, an anti-metal radio frequency identification electronic tag with anti-transfer function provided by the present utility model includes: an anti-metal layer 100, an adhesive layer 200, an antenna layer 300, a substrate layer 400, a bridge layer 500, a bridge conduction point 600, and a chip 700. The antenna layer 300 includes an antenna body 301 and an anti-transfer part 302.

[0018] The bridge conduction point 600 is a metal connection element. As Figure 1 shown, it penetrates through the substrate layer 400 and the antenna layer 300 and is connected to the chip 700 disposed in the antenna layer 300. Each bridge conduction point 600 is connected through the bridge layer 500 to form an antenna path.

[0019] The antenna layer 300 includes an anti-transfer part 302 and an antenna body 301 that are connected. The substrate layer 400 is provided with a notch 800 at a position corresponding to the connection; when an external force sufficient to cause the anti-transfer part 302 to separate from the antenna body 301 acts on the anti-transfer part 302, the notch 800 on the substrate layer 400 is torn by the external force (horizontally as shown in the attachment Figure 3 ), further causing the antenna layer 300 that forms the antenna path in the antenna body 301 and the anti-transfer part 302 to be torn, so that the antenna path is disconnected and the electronic tag cannot be used.

[0020] Among them, two bridge conduction points 600 are provided on the antenna body 301, and the two bridge conduction points 600 form an antenna path with the chip in the antenna layer 300 through the bridge layer 500. Among them, the bridge layer 500 is a connecting line connecting the bridge conduction points 600.

[0021] As Figure 3 shown, one bridge conduction point 600 is disposed close to the notch 800, and the other bridge conduction point 600 is disposed at another arbitrary position on the antenna body 301. In actual use, the bridge conduction points 600 can be disposed at any two positions on the antenna body 301 as required.

[0022] In summary, the antenna path of the present application is composed of: two bridge conduction points 600, a bridge layer 500, an antenna layer 300, and a chip 700.

[0023] Furthermore, the adhesive layer 200 is coated on the outer surface of the antenna layer 300, and the anti-metal layer 100 is coated on the adhesive layer 200. Among them, the area of the anti-metal layer 100 is the same as the area of the antenna body 301, specifically as Figure 2 shown in the shaded part.

[0024] Now, the technical solution of the present utility model will be described in detail:

[0025] Regarding the antenna layer 300 and the chip 700 therein:

[0026] The chip 700 is placed at any position within the antenna body 301. At the same time, the bottoms of both of the two bridge conduction points 600 are provided within this antenna body 301. Further, as Figure 1 shown, a substrate layer 400 is covered on the antenna layer 300, and the bridge conduction points 600 pass through the substrate layer 400 and are exposed outside. The parts of the two bridge conduction points 600 exposed outside the substrate layer 400 are covered by the bridge layer 500.

[0027] The outer layer of the antenna body 301 in the antenna layer 300 is covered with an adhesive layer 200, and an anti-metal layer 100 is provided outside the adhesive layer 200, which is used to reduce the interference of metal on the radio frequency signal, so as to ensure that the communication distance and reading performance remain available when applied on the metal surface.

[0028] Based on the above structure, the chip 700 in the antenna layer 300 forms a loop by means of the bridge layer 500 and the bridge conduction points 600. The antenna layer 300 can be prepared by an aluminum etching or silver paste printing process. In particular, the bridge layer 500 and the antenna layer 300 can be symmetrically arranged on both sides of the substrate layer 400 ( Figure 1 ), or, the bridge layer 500 and the antenna layer 300 are on the same side of the substrate layer 400. When the bridge layer 500 and the antenna layer 300 are on the same side of the substrate layer 400, an isolation layer is added: the bridge layer 500, the isolation layer, the antenna 300, the substrate 400, the adhesive layer 200, and the anti-metal layer 100 are arranged in sequence. Among them, the isolation layer is an insulating layer for isolating the bridge layer 500 and the antenna layer 300 (the area of the insulating layer only covers the bridge layer 500 and the conduction points 600 connected to the bridge layer 500).

[0029] Select according to the actual preparation process: when using the silver paste printing process for preparation, the bridge layer 500 can be on the same side of the substrate as the antenna. The anti-metal layer 100 covers the main antenna part (antenna body 301) to form the radio frequency identification ability on the metal surface.

[0030] Regarding the anti-transfer part 302:

[0031] The antenna layer 300 of the antenna body 301 and the antenna layer 300 of the anti-transfer part 302 are integrated. The substrate part of the anti-transfer part 302 is an extension of the substrate layer 400. There are tear-away slits 800 at the positions corresponding to the connection between the substrate 400 and the anti-transfer part 302 and the antenna body 301. The antenna anti-transfer part 302 is outside the coverage of the anti-metal layer 100, and the number is preferably 1 to 5.

[0032] In actual use, an adhesive is further covered on the other side of the anti-metal layer 100 to attach this electronic tag to the commodity.

[0033] When the electronic tag is scanned, the bridge conduction point 600, the bridge layer 500, the antenna layer 300, and the chip 700 form a loop to achieve the purpose of the scanner obtaining information. The process is the same as the existing electronic tag scanning principle.

[0034] When the antenna is subjected to an external force, refer to Figure 2 and Figure 3 , the antenna body 301 and the anti-transfer part 302 are subjected to opposite acting forces, and the notch 800 is torn horizontally along the notch shown in Figure 3 (the dotted line direction in Figure 2 ), so that the antenna body 301 and the anti-transfer part 302 are separated, and the antenna path is disconnected, so that the electronic tag cannot be recognized by the reader, achieving the purpose of preventing the electronic tag from being reused.

[0035] In the technical solution of the present invention, the anti-metal layer 100 is a ferrite material, an iron-silicon-aluminum material or an alloy powder coating (at least one of iron-nickel alloy flake powder, iron-cobalt alloy flake powder, iron-silicon-aluminum alloy flake powder or iron hydroxide flake powder).

[0036] In summary, the anti-transfer structure provided by the present invention can ensure that it can be quickly damaged under the action of a specific external force while maintaining the normal use of the whole electronic tag, achieving the purpose of preventing the reused tampered electronic tag.

[0037] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
