[0020] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0021] Please see Figure 1 This utility model provides an RFID self-adhesive label, including a label base layer 1, an antenna 2, a chip 3, and a multi-layer support structure 4. The antenna 2 is arranged around the bottom edge of the label base layer 1, and the chip 3 is attached to the middle of the bottom surface of the label base layer 1. The first end of the antenna 2 is connected to the chip 3, and the multi-layer support structure 4 is provided at the bottom of the label base layer 1.

[0022] Specifically, when the reader approaches the tag base layer 1, the antenna 2 generates a current under the electromagnetic induction of the reader to activate the chip 3 to send a signal. The reader then decodes the signal and transmits the data to the background system to complete the identification.

[0023] Please see Figure 2-5 This utility model provides an RFID self-adhesive label. The multi-layer support structure 4 includes a first adhesive coating 41, a cardboard layer 42, a covering film 43, a second adhesive coating 44, and a release paper 45. The bottom surface of the label base layer 1 is coated with the first adhesive coating 41. The label base layer 1 is attached to the top surface of the cardboard layer 42 through the first adhesive coating 41. The covering film 43 is provided at the four corners of the top surface of the cardboard layer 42. The edges of the label base layer 1 are nested inside the covering film 43 at the four corners. The bottom surface of the cardboard layer 42 is coated with the second adhesive coating 44. The release paper 45 is attached to the surface of the second adhesive coating 44.

[0024] To further explain, the cardboard layer 42 is made of cardboard, which has excellent hardness and resistance to deformation. This allows the cardboard layer 42 to provide good back support for the label base layer 1, making it less prone to bending and deformation. The cardboard layer 42 matches the size and specifications of the label base layer 1, and it can provide full support for the label base layer 1 without causing local collapse.

[0025] To further explain, a release layer 421 is coated on the top surface of the cardboard layer 42. The cardboard layer 42 is bonded and covered to the first adhesive coating layer 41 through the release layer 421. The release layer 421 acts as an isolation layer to maintain the adhesiveness of the first adhesive coating layer 41, allowing the label base layer 1 to be peeled off and used separately.

[0026] The transparency of the coating film 43 is not less than 90%, ensuring that the coating film 43 will not obscure the pattern on the label base layer 1.

[0027] Specifically, by setting a multi-layer support structure 4 at the bottom of the label base layer 1, when in use, the cardboard layer 42 can be glued and fixed to the working surface by peeling off the release paper 45 and applying the second adhesive coating 44. The cardboard layer 42 has excellent hardness and anti-deformation ability, which enables the cardboard layer 42 to provide good back support for the label base layer 1, making it less prone to bending and deformation, and more sturdy and durable.

[0028] A release layer 421 is applied to the top surface of the cardboard layer 42. The release layer 421 acts as an isolation layer, which can maintain the adhesiveness of the first adhesive coating layer 41. When in use, the covering film 43 can be torn off, and then the label base layer 1 can be peeled off from the surface of the cardboard layer 42. The label base layer 1 can be removed and used separately for pasting and fixing to flexible items such as clothing. Users can choose different installation methods according to their needs, making it more adaptable.
