In contrast, if a determination is made that the RFID tag is traveling through a facility [1232:YES], then 1236 is optionally performed where a WOT is determined during which the RFID tag's receiver is to be operational. 1236 is optional since the RFID tag can be pre-programed with a WOT value. In other scenarios, a value for the WOT is determined by the RFID tag and/or a remote device. The WOT value is determined based on environmental conditions and/or system conditions. Notably, the WOT value is variable. This feature of the present solution allows minimization of the RFID tag's system power, minimizes tag read collisions, and identification of moving RFID tags without reading all static/stationary RFID tags.

Once the RFID tag has knowledge of the WOT value, then 1238 is performed where its operational mode is transitioned from the power recharging mode to the communications mode in which its receiver is enabled. In the communications mode, the RFID tag uses an internal clock/timer (e.g., clock/timer 214 of FIG. 1) to determine if the WOT has expired. If not [1240:NO], then the RFID tag performs operations in 1242 to receive and respond to at least one interrogation signal. In so [1240:YES], then 1226-1242 are repeated until motion is no longer detected, a stationary state signal has been communicated from the tag to a tag reader, a power source (e.g., power source 236 of FIG. 2) has a certain level of charge, and/or a control signal is received from an external device to disable the receiver. Subsequently, 1246 is performed where method 1200 ends or other processing is performed (e.g., return to 1214 of FIG. 12A).
