A system and method of determining unprocessed items which is used to verify an item count based upon the number of radio frequency identification labels that have responded with their label information. The system includes an imaging system for producing image information about items in a container, and a computer for receiving label information from a radio frequency identification label reader following interrogation of a number of radio frequency identification labels on the items in the container, for producing a first count of the items from label information obtained from the number of radio frequency identification labels, for producing a second count of the items in the container from the image information, and for comparing the first count to the second count to produce a third count of the items not processed by the radio frequency identification label reader.
