Abstract
RFID reader systems, readers, components, software and methods can inventory RFID tags in one or more early attempts. Then they can facilitate the inventoried RFID tags to refrain from participating in one or more subsequent inventorying attempts. In some embodiments, an inventoried indicator in the tag becomes updated upon backscattering. The updated value is used by the tag to recognize a subsequent attempt, and thus refrain from participating in it. This permits the subsequent attempt to be used more intensively for inventorying the more elusive, harder-to-read tags, especially in more demanding scenarios.
