Abstract: Storage units including platforms that are outfitted with RFID antennas and auxiliary sensors detect changes in loading on the platforms based on changes in loading determined by the auxiliary sensors or changes in signals received by the RFID antennas. The platforms include surfaces for receiving items tagged with RFID transmitters thereon, such as items of common types and variable weights. An interaction involving the placement of an item on the platform, or the removal of the item from the platform, is detected by the auxiliary sensors. The energization of an RFID field is triggered in response to the detected interaction, and an item is identified where an RFID signal transmitted by the item is present at one time and absent at another time.
