RFID is a technology that uses radio waves to transfer data from an electronic tag, called an RFID tag or label, through a reader attached to an object for the purpose of identifying and tracking the object. Some RFID tags can be read from several meters away and beyond the line of sight of the reader.

What is a wireless technology used for tagging and tracking?
An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods.
