What is the difference between transponder,smart tag and RFID tag?

- Dec 04, 2018 -

Originally in the technical field, transponders are electronic modules capable of transmitting information and replying 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. Smart Labels are, to be precise, an innovation in RF tags that consist of sticky labels and ultra-thin RF tags. Smart tags combine RF technology with the convenience of flexible label printing. Smart tags with read and write capabilities can be programmed multiple times, following the coding rules at the time the tag was originally created. 


Electronic tags can be classified into low frequency electronic tags, high frequency electronic tags, ultra high frequency electronic tags, and microwave electronic tags depending on the frequency. Depending on the package type, it can be divided into credit card labels, linear labels, paper labels, glass tube labels, round labels, and special-purpose shaped labels.

 The RFID reader (reader/writer) 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. A typical reader includes a high frequency module (transmitter and receiver), a control unit, and a reader antenna.
