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 is programmed to associate information included in a first signal corresponding to a response from a radio frequency identification tag with a first item if the processor receives the first signal 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 first antenna radiates radio frequency signals. If the processor receives a predetermined number of first signals while at least a portion of the first item is within the first area, wherein the predetermined number of first signals includes information identifying the same radio frequency identification tag, the processor thereafter prohibits association of the information with a second item that is upstream from the first item.
