[0002] With the continuous evolution of Radio Frequency Identification (RFID) technology, electronic tags have been deployed on a large scale in logistics, retail, industrial manufacturing, and intelligent transportation to achieve contactless, high-speed data collection at the item level. However, as the application scope of electronic tags continues to expand, they also face many challenges in practical use, among which waterproof performance and anti-counterfeiting applications are two particularly critical aspects.
[0003] Traditional labels lack effective anti-transfer structural designs, making them easily detached and re-attached to other items, leading to distorted product traceability and ineffective anti-counterfeiting measures, causing economic losses to businesses and consumers. To address waterproofing, some solutions employ simple sealing, but often neglect anti-transfer functionality; while labels focused on anti-transfer tend to rely on complex adhesive structures, making it difficult to balance waterproofing performance with ease of production. Although traditional plastic labels offer some improvement in waterproofing, their anti-transfer design is flawed, allowing them to retain full functionality even after being removed, failing to achieve "disinfection upon removal."

[0026] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0027] The inventors, through analysis of existing technologies, discovered that traditional labels lack effective anti-transfer structural designs, making them easily detachable and re-attached to other items. This leads to distorted product traceability and ineffective anti-counterfeiting measures, causing economic losses to businesses and consumers. To address the waterproofing issue, some solutions employ simple sealing methods, often neglecting anti-transfer functionality. Labels focused on anti-transfer tend to rely on complex adhesive structures, making it difficult to balance waterproofing performance with ease of production. While traditional plastic labels offer some improvement in waterproofing, their anti-transfer design is flawed; they retain full functionality even after being removed, failing to achieve "disinfection upon removal."
[0028] In the embodiments of this application, addressing the problems of existing RFID electronic tags lacking effective anti-transfer design, being easily maliciously recycled and reused, and having high light transmittance making them easy to imitate, this application proposes a waterproof and anti-transfer RFID electronic tag, including a bridging connection point 6, a chip 5, a front antenna layer 3, a substrate layer 1, a back antenna layer 2, and a first easily tearable component 9; the substrate layer 1 is disposed between the front antenna layer 3 and the back antenna layer 2, and the chip 5 is disposed on the front antenna layer 3 or the back antenna layer 2; the bridging connection point 6 connects the front antenna layer 3 and the back antenna layer 2; the first easily tearable component 9 is connected to the substrate layer 1, and part of the chip 5 is disposed in the first easily tearable component 9; when the first easily tearable component 9 is torn off, part of the chip 5 breaks off along with the first easily tearable component 9. By partially integrating the first easily tamper-evident component 9 with the chip 5, the "tear-off" function is achieved, completely solving the problem of the tag being maliciously transferred and reused. The front antenna layer 3 and the back antenna layer 2 form a complete circuit through the bridge connection point 6. The structure is compact, taking into account both communication performance and anti-transfer function. At the same time, it does not require a complex sealing structure, and the production process is simple, making it suitable for industrial mass production needs.
[0029] Reference Figure 1-5 The present invention illustrates a waterproof and transfer-resistant radio frequency identification electronic tag, including a bridge connection point 6, a chip 5, a front antenna layer 3, a substrate layer 1, a back antenna layer 2, and a first easily tearable component 9;
[0030] The substrate layer 1 is disposed between the front antenna layer 3 and the back antenna layer 2, and the chip 5 is disposed on the front antenna layer 3 or the back antenna layer 2; the bridging connection point 6 connects the front antenna layer 3 and the back antenna layer 2; the first tear-resistant component 9 is connected to the substrate layer 1, and part of the chip 5 is disposed on the first tear-resistant component 9.
[0031] When the first tearable component 9 is torn off, part of the chip 5 breaks off along with the first tearable component 9.
[0032] It should be noted that, referring to Figure 3-4By integrating the chip and employing an easy-tear design, an anti-transfer core is constructed. Combined with a dual-sided antenna and a waterproof substrate, this addresses the pain points of traditional tags' anti-transfer failure and unstable communication in humid environments. The partial bonding design between the first easy-tear component 9 and the chip 5 achieves "disconnection upon removal," while the bridging conduction point 6 ensures the integrity of the dual-sided antenna circuit, balancing communication performance and anti-transfer reliability. The overall structure is compact and suitable for industrial production.
[0033] As an example, the chip 5 is disposed in the first easily tearable component 9, accounting for 30%-50% of the total area of the chip 5. This 30%-50% area ratio is precisely optimized: too low a ratio would cause the chip 5 to continue functioning normally after breakage, failing to prevent transfer; too high a ratio might affect the initial communication performance of the chip 5. This range ensures that the core function of the chip 5 is damaged beyond repair after breakage, while also guaranteeing the stability of signal transmission during normal use of the tag.
[0034] The following will further describe a waterproof and transfer-resistant radio frequency identification electronic tag in this exemplary embodiment.
[0035] Reference Figure 5 In one embodiment of this application, a plurality of second tear-resistant components 10 connected to the substrate layer 1 are further included, and each of the plurality of second tear-resistant components 10 has an antenna coil 8 distributed on the front antenna layer 3.
[0036] It should be noted that the second easily tamper-evident component 10 forms a "multi-node anti-transfer" layout through the distributed antenna coil 8. Not only will the chip 5 break and fail, but tearing off any of the second easily tamper-evident components 10 will also damage the integrity of the antenna circuit, further improving the reliability of anti-malicious transfer and preventing tag reuse by circumventing the first easily tamper-evident component 9.
[0037] In one embodiment of this application, the connection between the second tear-resistant component 10 and the substrate layer 1 is treated with a 40° chamfer.
[0038] It should be noted that the 40° chamfer design precisely controls the structural strength of the connection, ensuring the structural stability of the label during normal use and allowing the connection to break precisely when torn, avoiding irregular damage during tearing that could cause the antenna coil 8 to not be completely disconnected, thus ensuring the effectiveness and consistency of the anti-transfer function.
[0039] In one embodiment of this application, a release paper layer 4 is also included, which is connected to the back antenna layer 2 by an adhesive 7.
[0040] It should be noted that the release paper layer 4 provides protection for the self-adhesive 7, preventing the label from losing its adhesiveness before use; the self-adhesive 7 not only achieves a firm bond between the label and the object being applied, but also seals the outer surface of the antenna layer 2 on the back, preventing moisture from seeping into the label from the bonding surface, forming a double waterproof protection with the waterproof substrate, and improving adaptability to humid environments.
[0041] In one embodiment of this application, the substrate layer 1 is made of PET, TPU, EVA or PP.
[0042] It should be noted that this type of polymer material has excellent waterproof, weather-resistant and flexible properties, avoiding the problems of short circuits and corrosion of electronic components caused by water absorption in traditional paper substrates; at the same time, the material itself is not easily torn or deformed, and can provide stable support for the antenna layer and chip 5, ensuring the structural integrity and communication stability of the tag in complex environments.
[0043] In one embodiment of this application, the connection between the first tearable component 9 and the substrate layer 1 is treated with a 40° chamfer.
[0044] It should be noted that the chamfering creates a stress concentration point at the connection, concentrating the force on this area during tearing, ensuring that the first easily torn component 9 breaks precisely and the fracture surface is flat, thus preventing the chip 5 from not being completely separated; at the same time, the 40° angle design balances the fracture sensitivity and structural strength, preventing accidental breakage due to slight contact.
[0045] In one embodiment of this application, an opaque coating layer is further included, the opaque coating layer being disposed on the side of the front antenna layer 3 away from the substrate layer 1.
[0046] It should be noted that the opaque coating layer can cover the structural layout of the front antenna layer 3 and chip 5, preventing malicious observation and imitation, and improving anti-counterfeiting security; at the same time, the coating layer has a certain degree of waterproof and scratch-resistant properties, which can prevent water from seeping in from the front and protect the antenna layer and chip 5 from external wear, extending the label's service life.
[0047] In one embodiment of this application, the antenna coils 8 of both the front antenna layer 3 and the back antenna layer 2 are prepared by aluminum etching or silver paste printing. The linewidth of the antenna coil 8 is 0.1-0.3 mm and the line spacing is 0.15-0.4 mm.
[0048] It should be noted that the aluminum etching process ensures high precision and good conductivity of the antenna coil 8, while the silver paste printing process is suitable for mass production and has controllable costs. The line width of 0.1-0.3mm and the line spacing of 0.15-0.4mm balance communication performance and structural compactness, achieving stable signal transmission within a limited tag area, while ensuring that the antenna coil 8 cannot be easily repaired after breakage, and the easy-tear components enhance the anti-transfer effect.
[0049] In one embodiment of this application, the thickness of the first tearable component 9 is 0.08-0.15 mm, and the material of the first tearable component 9 is the same as that of the substrate layer 1.
[0050] It should be noted that the same material as the substrate layer 1 ensures the compatibility and structural stability of the connection between the component and the substrate, avoiding poor adhesion or easy cracking due to material differences; the thickness of 0.08-0.15mm ensures that the component has sufficient structural strength to support the chip 5, and can be easily broken when torn, taking into account both reliability and anti-transfer sensitivity.
[0051] In one embodiment of this application, the edge of the first tearable component 9 is provided with a protrusion that facilitates tearing, and the width of the protrusion is 3-5mm.
[0052] It should be noted that the width of the raised part is designed to be 3-5mm, which is suitable for the pressing and tearing operation of an adult's fingertip, providing a clear point of force application and avoiding slippage and difficulty in applying force when tearing; at the same time, the raised part will not increase the overall size of the label or take up extra space due to excessive width, ensuring the label's thinness and ease of use. At the same time, the raised part and the first easy-tear component 9 are integrally molded and made of the same material, which can ensure that the force is evenly transmitted to the 40° cut corner area at the connection point when tearing, ensuring precise breakage of the component and further enhancing the "disappears upon tearing" anti-transfer effect.
[0053] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
