2. Radio-frequency identification - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_identification

   An early work exploring RFID is the landmark 1948 paper by Harry Stockman, [10] who predicted that "Considerable research and development work has to be done before the remaining basic problems in reflected-power communication are solved, and before the field of useful applications is explored."

3. Smart label - Wikipedia

   en.wikipedia.org/wiki/Smart_label

   A smart label, also called a smart tag, is an extremely flat configured transponder under a conventional print-coded label, which includes chip, antenna and bonding wires as a so-called inlay. [ 1 ] [ 2 ] [ 3 ] The labels, made of paper, fabric or plastics, are prepared as a paper roll with the inlays laminated between the rolled carrier and ...

4. Clipped tag - Wikipedia

   en.wikipedia.org/wiki/Clipped_tag

   The clipped tag is a radio frequency identification (RFID) tag designed to enhance consumer privacy. RFID is an identification technology in which information stored in semiconductor chips contained in RFID tags is communicated by means of radio waves to RFID readers. The most simple passive RFID tags do not have batteries or transmitters. They ...

5. Chipless RFID - Wikipedia

   en.wikipedia.org/wiki/Chipless_RFID

   Chipless RFID tags, on the other hand, function without a communication protocol. They employ a grid of dipole antennas that are tuned to different frequencies. The interrogator generates a frequency sweep signal and scans for signal dips. Each dipole antenna can encode one bit. The frequency swept will be determined by the antenna length.

6. Real-time locating system - Wikipedia

   en.wikipedia.org/wiki/Real-time_locating_system

   Wireless RTLS tags are attached to objects or worn by people, and in most RTLS, fixed reference points receive wireless signals from tags to determine their location. [1] Examples of real-time locating systems include tracking automobiles through an assembly line , locating pallets of merchandise in a warehouse, or finding medical equipment in ...

7. Item-level tagging - Wikipedia

   en.wikipedia.org/wiki/Item-level_tagging

   Item-level tagging (or RFID item-level tagging, also known as ILT) is the tagging of individual products, as opposed to case-level and pallet-level tagging. [1] Item-level tagging is used to track individual items in order to better control inventory, by providing retailers with the ability to tag individual items on the retail floor. [2]
