RFID is excellent and reliable indoors or in situations where close proximity to tag readers is feasible, but has limited range and still requires costly readers. RFID stands for Radio Frequency Identification. This technology uses electromagnetic waves to receive the signal from the targeting object to then save the location on a reader that ...
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.
RFID is synonymous with track-and-trace solutions, and has a critical role to play in supply chains. RFID is a code-carrying technology, and can be used in place of a barcode to enable non-line of sight-reading. Deployment of RFID was earlier inhibited by cost limitations but the usage is now increasing.
A communications satellite’s channels are called transponders because each is a separate transceiver or repeater.With digital video data compression and multiplexing, several video and audio channels may travel through a single transponder on a single wideband carrier.
RFID Journal is an independent media company devoted solely to radio frequency identification and its business applications.A bi-monthly print publication and online news and information source, the journal offers news, features that address key adoption issues, case studies, and white papers written by academics and industry insiders on different aspects of RFID technology.
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.
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.
