Transceiver and transponder explained

Both the term Transceiver and Transponder has totally a different meaning and function.

Transceiver: The meaning is hidden inside the word itself. Transmitter + Receiver = Transceiver. Meaning, a transceiver is a device  which consists of both transmitter and receiver circuitry. BLE modules, nRF, Lora etc are good examples of transceivers

Transponder: A transponder on the other hand can only either transmit data or receive data and not both. Most commonly transponders are small devices with unique ID code and an antenna with minimum circuitry.  433MHz transmitter, RFID tags etc are examples of transponders.


Now you should be clear with the meaning of RFID transponder chip a.k.a RFID tags. These devices can only transmit data and cannot receive any
