Abstract
According to certain inventive techniques, a system includes a plurality of shelves in an interior chamber of a cold-storage apparatus, an RFID antenna assembly in the cold-storage apparatus, and a controller. Each of the shelves can support items that are connected a corresponding RFID tag. The RFID antenna assembly includes a plurality of RFID antenna elements that direct a transmission of radio frequenc(ies) towards the plurality of shelves. The controller is in communication with the RFID antenna assembly and can individually and separately control each of the RFID antenna elements.
