Abstract
A reader generates a scanning beam for reading a bar code symbol on a selected item. The reader includes a motion sensor or software program for discriminating between the selected item and other items also having bar code symbols thereon. The motion sensor or software program for discriminating between the items may discriminate between an item swept past the reader and stationary items, or an item moved into the field of view of the reader, held stationary and moved out of the field of view and stationary or moving items or between an item placed within a predetermined distance range and other items.
