What technology emits radio waves through tags?

Radio frequency identification technology emits radio waves through tags, and the reader receives the radio waves to read the data.

Radio frequency identification (RFID) is the abbreviation of Radio Frequency Identification.

The principle is contactless data communication between the reader and the tag to achieve the purpose of identifying the target. RFID is widely used. Typical applications include animal chips, car chip alarms, access control, parking lot control, production line automation, and material management.

Overview

Radio Frequency Identification (Radio Frequency Identification, RFID) is a type of automatic identification technology that uses wireless radio frequency for non-contact two-way data communication. It reads and writes recording media (electronic tags or radio frequency cards) to achieve the purpose of target identification 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 fast information exchange and storage technology, combines data access technology through wireless communication, and then connects to the database system to achieve non-contact two-way communication, thereby achieving the purpose of identification. , used for data exchange, connecting an extremely complex system in series. In the identification system, the reading, 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. Therefore, the data exchange method between the read/write device and the electronic tag is also correspondingly divided into load modulation and backscatter modulation.
