Abstract
A conveyor system for processing items on which radio frequency identification tags are disposed includes a frame, a conveyor disposed movably on the frame and that conveys items through a path of travel, each item having at least one respective radio frequency identification tag disposed thereon, at least one first antenna, at least one second antenna, a radio frequency receiver, and a processor. The processor associates a first signal with a first item if the processor receives the first signal from the receiver while at least a portion of the first item is within a first area that includes at least part of a second area into which the antenna radiates radio frequency signals. The first antenna radiates radio frequency signals if at least one item is in the path of travel within a third area that includes, and is larger than, the first area.
