Radio Frequency Identification (RFID) is the abbreviation for Radio Frequency Identification.
The principle is to carry out non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID has a wide range of applications. Typical applications include animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, and material management.
Radio Frequency Identification (Radio Frequency Identification, RFID) is a type of automatic identification technology that uses wireless radio frequency to carry out non-contact two-way data communication, and uses radio frequency to read recording media ( electronic tags or radio frequency cards). Write, so as to achieve the purpose of identifying goals and data exchange, it is considered to be one of the most promising information technologies in the 21st century.
Radio frequency identification technology uses radio wave non-contact rapid information exchange and storage technology, combines wireless communication with data access technology, and then connects to the database system to achieve non-contact two-way communication, thereby achieving the purpose of identification and used for data exchange. Connect an extremely complex system in series. In the identification system, the reading and writing and communication of electronic tags are realized through electromagnetic waves. According to the communication distance, it can be divided into near-field and far-field. For this reason, the data exchange mode between the read/write device and the electronic tag is also divided into load modulation and backscatter modulation.
