A carrier structure has a plurality of cells. A corresponding plurality of objects having data carriers, such as radio frequency identification (RFID) tags, is placed in each cell. Each cell has an indicator associated therewith and is defined by walls that substantially prevent waves (such as RF waves) from propagating between cells. A control module is coupled to the carrier structure and is operative to selectively activate individual ones of the indicators. An automatic data collection device (such as an RFID reader) interrogates the data carriers of the objects placed in the cells, and the data carriers can provide response signals to the data collection device. The control module also monitors the response signals using an antenna present in each cell. If the data collection device selects a particular one of the responsive data carriers, the data collection device provides a notification signal to the control module to notify the control module of the selection. The control module then identifies and selects the cell of an object of interest having the selected data carrier affixed thereon, and initiates activation of the indicator associated with the selected cell, thereby identifying the location of the object of interest.
