CCD (Charge Coupled Device) scanners are similar to digital cameras in that they have hundreds of tiny LED lights arranged in one long row that capture a digital image of the barcode. They generally have very fast scan rates but limited read ranges (less than 3 inches) compared to a laser or imagerscanners. CCD scanners are also lower cost than other scanner types making them a great choice for point-of-sale and lower volume scanning applications where distance reading is not a concern.
