Principle Of RFID Reader

The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the radio frequency signal sent by 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 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.
The rapid rise of wireless radio frequency identification technology (RFID) is both the result of technological development and the embodiment of application needs. Since the 1990s, various applications around RFID have sprung up like mushrooms after rain. Today, we will briefly introduce RFID technology and its most important product-card reader.
