RFID is the abbreviation of radio frequency identification, which means radio frequency identification. It is a non-contact automatic identification technology. It is widely used in logistics management. Its working principle is to conduct non-contact two-way communication through radio frequency, and use wireless transceiver (commonly known as "passive RFID tag") to obtain information and transmit it to computer or automatic control system, so as to achieve the purpose of automatic identification and management of articles.

At present, there are two types of common reader / writer devices in the market: fixed reader/writer and handheld  RFID reader. Handheld RFID reader devices usually use batteries as the power supply. The external dimensions of the reader / writer are generally less than 10cmx10cmx1cm. Currently, RFID handheld devices sold in the domestic market mainly have the following types:
