RFID tags, simply put, are intelligent barcodes that allow the tracking and management of an item. RFID tags have existed since the 1970s, but because of their relatively high cost, have only recently become a popular and viable replacement for the more “traditional” barcode.

RFID tags were originally used to track high-value or large items like livestock, railroad cars, or airline luggage when transported over a long distance. RFID tags, at that time, were a complex system of metal coils, antennas and glass called an “inductively coupled RFID tag.”
