[0034] The base layer 1 is made of one of polylactic acid, polyhydroxyalkanoate or polyethylene terephthalate, and the label can be effectively recycled after its service life ends, thereby reducing the environmental burden.

[0035] The protective layer 2 is made of polycarbonate, which protects the internal circuit from the external environment and increases the durability of the label.

[0036] The sensing layer 5 is an RFID chip or an NFC chip, which ensures stable signal transmission and reception capabilities in complex environments and achieves high-precision positioning and identification.

[0037] The information storage layer 4 is an EEPROM memory or a Flash memory, which is used to store detailed information of the item, such as a unique identification code, production date, batch number, usage status, etc. It supports multiple erasing and writing of data to ensure that the information is updated in a timely and accurate manner.

[0038] The adhesive layer uses an environmentally friendly adhesive to ensure firm adhesion while being easy to peel off without damaging the surface of the object being adhered, making it easy for the label to be recycled and reused.

The entire label is packaged to ensure that the electrical connection between the chip and the antenna and the information storage layer 4 is good, and there is no bubble or peeling between the protective layer and the substrate layer;

[0049] S6: Inspection and calibration: Conduct comprehensive inspection and calibration of finished labels, including signal strength, reading distance, information storage and reading accuracy, and durability testing. Defective products will be repaired or eliminated to ensure the quality of products leaving the factory.

Through the RFID reader, the information on the tag can be quickly read to achieve rapid inventory, search and tracking of items.

[0051] Embodiment 2

[0052] On the basis of the basic structure, NFC chip and temperature sensor are added.
