What Is the Definition of RFID?
How does RFID Journal define that term?
Our definition is this: any technology that enables a user to identify unique items, individuals or locations using radio waves.
There are passive systems in which a transponder has no power source, as well as active systems that employ a battery to broadcast a unique ID number. There are also semi-passive systems that utilize a battery to run a sensor and a microchip, but the tag communicates like a passive tag in that case.
Incidentally, there are highlighted words in all of our online articles (assuming that you have "Definitions" turned on in the Article Tools box). If you click on any term highlighted, you will be able to read a definition in a popup window.
