Abstract
A read chamber device is disclosed for use within a radio frequency identification (RFID) scanning enclosure which provides a means of reading a plurality of cartons moving through the enclosure via a conveyor belt. The enclosure is positioned over a section of the conveyor belt, such that the plurality of cartons on the conveyor belt pass directly through the enclosure. The read chamber device is positioned centrally to the enclosure and projects a read zone via an antenna positioned in-line with the flow of the conveyor which allows the read chamber to read a large variety of inlays without changing the configuration settings of the device. The RFID scanning enclosure also utilizes dynamic power indexing (DPI) to combine parameter inputs to create a smarter reader that can anticipate changes. The reader is then manipulated in real-time to adapt to the needs of each carton and the tunnel scanning environment.
