RFID tags are affixed to items in order to track them using an RFID reader and antenna. RFID tags transmit data about an item through radio waves to the antenna/reader combination. ... When the tag receives the transmission from the reader/antenna, the energy runs through the internal antenna to the tag's chip.Feb 28, 2019
