An input power on a tag is monitored. An input impedance of the tag is adjusted based on the monitored input power to increase a backscatter level of the tag. In one embodiment, an output voltage of a rectifier device is monitored. An input power to the tag is determined based on the output voltage. An input impedance of the tag is adjusted based on the input power to increase the backscatter level of the tag.
