Electronic tags (Tag): composed of coupling elements and chips, each RFID tag has a unique electronic code, attached to the object to identify the target object, commonly known as electronic tag or smart tag rfid electronic tag: active tag, passive tag, semi Active semi-passive tags.

RFID working principle: After the tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip (Passive Tag, passive tag or passive tag), or actively send a certain Frequency signal (Active Tag, active tag or active tag); after the reader reads and decodes the information, it is sent to the central information system for relevant data processing.

At present, the tire traceability marks on the market generally use the form of "bar code + sidewall information" to store various types of tire information, but the bar code and sidewall position information are located on the surface of the carcass, and the tire will soon be worn away after use . Once these information cannot be seen visually, it means that the tire information is lost, so that information such as tire model, pattern, and diameter cannot be identified. If tires are illegal and unsafe to use (unqualified tires, overloaded use, expired use, etc.), it will directly cause difficulties for the user's use, maintenance, and settlement of claims, leading to disputes and even frequent safety accidents. Waste of energy resources and damage to the environment.

    The application of RFID technology can standardize the orderly production and sales of the tire industry (prevent counterfeiting, OEM, and cross-country goods), realize tire lifecycle management; standardize the transportation industry, ensure personal and property safety; promote and standardize the tire retreading industry, and realize tires Circular Economy

   Demonstration of the application of RFID in tires: In the tire building process, the electronic tag is implanted inside the tire, which can withstand the deformation, high temperature and high pressure in the tire building and vulcanization process. The finished tire has undergone X-ray inspection, bubble inspection, dynamic balance and uniformity inspection, durability test inspection, etc., showing its reliable performance

    It can be seen that the combination of RFID technology and tire manufacturing technology can not only solve the problems encountered in the current tire identification and traceability processes, but also that the tires use RFID electronic tags embedded in the tires, which can write tire production data, sales data, and use Data, retreading data, etc., and the corresponding data can be collected and read through the terminal at any time, and combined with the corresponding management software, the recording and traceability of the tire's full life cycle data can be realized.
