Abstract
Systems and methods are disclosed for identifying one or more RF transponders from a group of RF transponders in an environment based on motions and associated change in radio signal strength. An example method includes causing a target object to move, in accordance with a target path, relative to remaining objects, and obtaining signal strength information of signals emitted from the transponders for a period of time during which the target object is moved and identifying the transponder associated with the target object based, at least in part, on analyzing the signal strength information in accordance with one or more criteria predetermined for the target path.
