What is another common name for an RFID Reader?

An RFID reader is commonly referred to as an interrogator because its primary function involves transmitting signals to RFID tags and then receiving the responses from them. This process of interaction mimics an interrogation, where the reader asks the tags questions by emitting radio waves and the tags reply with their stored information.

The use of the term "interrogator" highlights the active role of the reader in querying the tags for data rather than simply receiving or reading passive information. This terminology is widely accepted in the RFID industry and emphasizes the dynamic exchange of information occurring in RFID systems.
