Abstract: Features are disclosed for a wearable scanning device that can passively initiate scanning for wireless identifiers such as RFID tags. The wearable scanning device may include a force sensor, an accelerometer, or a motion activated switch that can initiate the scanning when detecting an action performed by an associate (e.g., lifting) without an express intent from the associate to scan.

Abstract: Features are disclosed for collecting wireless identifier signals such as from RFID tags to accurately determine the location of items associated with the wireless identifier. Carefully coordinating when to begin and end collection of the signals and analysis of the signals and signal characteristics (e.g., received signal strength) allow a carried item to be identified and its location determined. Additional features are described to further validate the location of the item.
