Background

Radio Frequency Identification (RFID) is one of automatic Identification technologies, and performs contactless bidirectional data communication in a Radio Frequency manner, and reads and writes a recording medium (an electronic tag or a Radio Frequency card) in a Radio Frequency manner, thereby achieving the purposes of identifying a target and exchanging data.

In order to realize real-time tracking and identification of goods, the conventional common method is to adopt a radio frequency identification technology, attach an electronic tag to goods, receive an ultrahigh frequency signal sent by a reader antenna after the electronic tag enters a magnetic field, send product information stored in the electronic tag by virtue of energy obtained by induced current, or actively send a signal of a certain frequency, read and decode the information by the reader, and send the information to an information system for data processing, so as to obtain the information of the goods.
