The common way to implement the technology is in the form of passive RFID systems, in which an RFID reader transmits a modulated RF signal to RFID tags each consisting of an antenna and an IC. The chip receives power from the antenna and responds by varying its input impedance, and thus modulating the backscattered signal. The ability to backscatter is strongly dependent on the surface on which the tag is mounted.
