What is RFID and how does RFID tags, RFID readers work | iNetra
Let’s learn what is RFID and how does RFID works. Radiofrequency identification uses electromagnetic fields to automatically recognize tags connected to tags. The technology behind RFID is based on radio waves and computer chips to transmit information. When you think about RFID, it’s easy to understand its advantages. Like barcodes, RFID uses radio waves to identify items. An RFID system has three main components: an RFID reader, an RFID tag, and a transceiver. The reader, or transceiver, transmits radio waves to activate the tag. The tag also called a transponder, responds to the radio signals whenever this object is in the reader’s range and transmits information to the reader. If the reader is within range of an RFID tag, it will detect and read the information contained within.
