CCD (Charge Coupled Device) CCD barcode scanners use an imaging charge coupled device to photograph barcodes. The photos are then decoded to a sequence of characters. Boasting a very fast scan speed, CCD barcode scanners often have a low scan range. These scanners do not contain moving parts, are extremely durable, and easy to use. Priced on the lower end, CCD barcode scanners from Barcode Discount are well suited for budget-conscious retailers.
