Abstract
A method of adjusting operation of an RFID tag for an environment is described. The method includes sensing an aspect of the environment. The method also includes sending an instruction, based on the sensed aspect of the environment, to the RFID tag. The instruction encoded in a TUNE command. The instruction causes the RFID tag to perform a specific act. The specific act includes one of the following: turning a sub-circuit of the RFID tag's semiconductor chip on; turning a sub-circuit of the RFID tag's semiconductor chip off; altering a bias current within a sub-circuit of the RFID tag's semiconductor chip; altering a bias voltage within a sub-circuit of the RFID tag's semiconductor chip; and, adjusting a threshold within a sub-circuit of the RFID tag's semiconductor chip.
