How RFID Works

After the tag enters the magnetic field, it receives the RF signal emitted by the reader, and transmits product information stored in the chip (Passive Tag, Passive Tag or Passive Tag) using the energy obtained by the induced current, or actively transmits a signal of a certain frequency (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.
