RFID has had a history of more than 50 years since its birth in 1948,but it has flourished in recent years.Especially in the last two or three years,RFID technology has been rapidly developed.The so-called RFID technology is referred to an automatic identification technology that uses radio waves to communicate.The basic principle is that using the electromagnetic coupling between the reader and the tag which is pasted at the objects to communicate data.Compared to the traditional identification techniques,RFID has many advantages.It has a long-distance rapid identification,a large quantity of data storage,and the data can be updated.RFID technology is the advanced form of automatic identification.Its unique technical advantages will make outstanding contributions to human's life and production.With RFID as the research object,this paper expounds the definition of RFID,gives an outline of the components,operating principles and classification of RFID system,analyzes the advantages of RFID technology and introduces the main fields of application.
