Duet scanner retailers can now scan anything at the point-of-sale; small items, large bulky items, even items that are not individually bar coded. Now retailers can provide quicker checkouts and enjoy the benefits of increased accuracy of the scan data. Most items are simply presented or swept in front of the scanner. With the Duet scanner unique single line capability the need to manually key items without bar codes, such as unpacked or specialty products, is eliminated. Simply direct the pointer beam that exits out the back of the scanner at a bar coded PLU list, target the correct item, press the trigger and the single line captures the data.
