Radio frequency identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals, without the need to establish mechanical or optical contact between the identification system and specific targets.
Many people may think that the application of RFID is complicated, but in fact the basic working principle of RFID technology is not complicated: 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 stored in the chip. Information (Passive Tag, passive tag or passive tag), or the tag actively sends a signal of a certain frequency (Active Tag, active tag or active tag), the reader reads and decodes the information, and then sends it to the central information system for processing Related data processing.
A complete RFID system is composed of a reader and an electronic tag, which is a so-called transponder, and an application software system. Its working principle is that the reader emits radio wave energy of a specific frequency to drive the circuit When the internal data is sent out, the Reader will receive and interpret the data in order and send it to the application for corresponding processing.
