What technology is rfid?
rfid is radio frequency identification, which is a kind of automatic identification technology. It is a kind of automatic identification technology and is used by a special scanning instrument. The system has only two basic components, and there are controls to check and track objects. Non-contact two-way data communication is carried out by radio frequency, and the recording medium is read and written by radio frequency, so as to achieve the purpose of identifying targets and data exchange. It is considered to be one of the most potential information technologies in the 21st century.
working principle
The reader can be a read or read/write device according to the structure and technology used, and is the information control and processing center of the RFID system. The reader usually consists of a coupling module, a transceiver module, a control module and an interface unit. Half-duplex communication is generally used to exchange information between the reader and the tag, and the reader provides energy and timing to passive tags through coupling. In practical applications, management functions such as collection, processing and remote transmission of object identification information can be further realized through Ethernet or WLAN.
