Originally in the field of technology, transponders are electronic modules that can transmit information and reply information. In recent years, due to the rapid development of radio frequency technology, transponders have a new meaning and meaning, and are also called smart tags or tags. The RFID electronic tag reader wirelessly communicates with the RFID electronic tag through the antenna, so that the tag identification code and the memory data can be read or written. RFID technology can recognize high-speed moving objects and recognize multiple labels at the same time, which is quick and easy to operate.
In the future, the rapid development of RFID technology is of great significance to the progress of the Internet of Things.
