The RFID tags includes either fixed or programmable logic for processing the transmission and sensor data, respectively. [citation needed] RFID tags can be either passive, active or battery-assisted passive. An active tag has an on-board battery and periodically transmits its ID signal. [17]
The microcontroller can perform a variety of computing tasks, including sampling sensors, and reporting that sensor data back to the RFID reader. WISPs have been built with light sensors, temperature sensors, and strain gauges. Some contain accelerometers. [2] WISPs can write to flash and perform cryptographic computations.
These sensors, along with the required RFID electronics, can be fabricated on paper or e-textiles for wireless powered disposable sensing devices. [68] Applications have been established for point-of-care medical diagnostics , where portability and low system-complexity is essential.
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.

Chipless rfid operating principle. A. Vena, E. Perret, and S. Tedjini, 2013. Like various existing RFID technologies, chipless RFID tags are associated with a specific RF reader, which questions the tag and recovers the information contained in it. The operating principle of the reader is based on the emission of a specific electromagnetic (EM ...
RFID tech allows NFL officials staring at monitors in New York to read data on the flight of a football. The virtually weightless microchips inside the balls weren’t initially designed to ...
Transponder timing (also called chip timing or RFID timing) is a technique for measuring performance in sport events. A transponder working on a radio-frequency identification (RFID) basis is attached to the athlete and emits a unique code that is detected by radio receivers located at the strategic points in an event.
