Dual-frequency transponder

A dual-frequency transponder is a transponder that combines two different RFID frequency ranges in a single component, typically HF or NFC and UHF. This allows an object to be captured either selectively at close range or automatically over longer distances, depending on the process. The design combines different requirements from manual handling and stationary identification in one shared data carrier. Such concepts are used with dual-frequency transponders    when an object needs to be captured in different reading scenarios using a single carrier. The use of an RFID reader across both frequency worlds simplifies continuous identification of an object from an individual operating point through to automated capture in the material flow.
