The key technologies of every link of the Internet of things chain were RFID radio frequency identification technology, sensors, smart chips and telecommunications network carriers' wireless transmission.

As a vanguard of Internet of Things, RFID radio frequency identification technology is to achieve a non-contact transmission of information and achieve the purpose of identification technology, its basic principle is the use of radio frequency signal and the spatial coupling (inductive or electromagnetic coupling), or the transmission characteristics of radar reflectivity and realize automatic identification of objects to be identified, the simplest RFID system consists of three parts, electronic tags, readers and antennas.
