When a radio-frequency identification (RFID) tag reader transmits a query, each RFID tag within range responds by transmitting a reply and switching the state of its inventoried flag for a persistence time depending on the session of query. Addressing a query to tags with inventoried flags in a particular state provokes replies from only tags with inventoried flags in that state. These inventoried flags can be used to silence tags, potentially accelerating queries of large groups tags. If a reader transmits a low-power query, that low-power query switches the state of the inventoried flags of the tags within range. If the reader transmits a higher-power query in the same session while the inventoried flags of those tags are still in the switched state, then those tags won't respond to the higher-power query. This enables tailoring the modulation rate and duration of higher-power query to tags that are farther from the sensor.
