Radio Frequency Identification (RFID) is a wireless system comprised of two components: tags and readers that uses electromagnetic fields to automatically identify and track tags attached to objects.
Reference Definition by Internetofthingsagenda.techtarget.com: Radio Frequency Identification (RFID) is a technology that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum to uniquely identify an object, animal, or person. RFID is coming into increasing use in industry as an alternative to the bar code. The advantage of RFID is that it does not require direct contact or line-of-sight scanning. An RFID system consists of three components: an antenna and transceiver (often combined into one reader) and a transponder (the tag).
