The principle of electronic tags

   RFID tags : Composed of coupling elements and chips, each tag has an electronic code, is attached to an object to identify the target object, and has the function of storing the information to be identified and transmitted. In specific applications, the composition of an RFID system will vary depending on the application purpose and environment, but from the perspective of the working principle of an RFID system, the system generally consists of RFID...It consists of three parts : electronic tag , reader, and transmitting/receiving antenna.

   RFID electronic tags are generally low-power integrated circuits with coils, antennas, memory, and control systems.

   There are many ways to classify RFID systems. In common applications, they are classified according to frequency. Based on different operating frequencies, they can be divided into the following four types:

   (1) Microwave (2.45-5.8 GHz). This frequency band can achieve long-distance identification, with an identification distance of up to 100 m, but it is also the most expensive and is mainly used in intelligent transportation systems.

   (2) Low frequency (120～135 kHz). This frequency band has strong field penetration, is unrestricted in use, its performance is not affected by the environment, and it is inexpensive. The maximum recognition distance is generally less than 60 cm. It is mainly used in access control, "one-card" consumption management, vehicle management and other systems.

   (3) High frequency (10-15 MHz). Compared with low frequency, this frequency band has the advantages of anti-collision and simultaneous identification of multiple tags, but its performance is affected by the environment and the identification distance is generally less than 100 cm. It is mainly used in systems such as library management and logistics.

   (4) Ultra-high frequency (850-960 MHz). Compared with high frequency, this frequency band has the advantage of enabling long-distance identification, with a maximum identification distance of up to 10 m. However, its performance is greatly affected by the environment and the price is also higher. It is mainly used in railway vehicle identification, container identification and other systems.
