Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver , and a transmitter .
RFID has found its importance in a wide range of markets, including livestock identification and Automated Vehicle Identification (AVI) systems because of its capability to track moving objects. These automated wireless AIDC systems are effective in manufacturing environments where barcode labels could not survive.

At that point, he viewed radio-frequency identification (RFID) as essential to the Internet of things, [31] which would allow computers to manage all individual things. [ 32 ] [ 33 ] [ 34 ] The main theme of the Internet of things is to embed short-range mobile transceivers in various gadgets and daily necessities to enable new forms of ...
A wireless identification and sensing platform (WISP) is an RFID (radio-frequency identification) device that supports sensing and computing: a microcontroller powered by radio-frequency energy. [1] That is, like a passive RFID tag, WISP is powered and read by a standard off-the-shelf RFID reader, harvesting the power it uses from the reader's ...
Singulation is a method by which an RFID reader identifies a tag with a specific serial number from a number of tags in its field. This is necessary because if multiple tags respond simultaneously to a query, they will jam each other. In a typical commercial application, such as scanning a bag of groceries, potentially hundreds of tags might be ...
An EPC RFID tag used by Wal-Mart. The Electronic Product Code (EPC) is designed as a universal identifier (using an idiosyncratic numerical code for each different commodity [1]) that provides a unique identity for every physical object anywhere in the world, for all time.
