RFID generally refers to Radio Frequency Identification technology (a communication technology term).
RFID, also known as Radio Frequency Identification, is a communications technology that allows the identification of a specific target and the reading and writing of related data via radio signals without the need to establish mechanical or optical contact between the identification system and the specific target.
Expanded informationRFID technology's basic working principle is not complicated:
Tag into the magnetic field, receive decoder issued by the radio frequency signals, by virtue of the inductive current of the energy gained by sending out the product information stored in the chip (passive tags or passive tags), or by the tags to actively send a certain frequency of signals decoder to read the information and decode the information, and then send it to a centralized Information system for relevant data processing.
