A Comprehensive Guide to Barcode Scanners and How They are Transforming the Retail Industry Barcodes are essentially a series of parallel lines and spaces that represent information such as a product name, price and other identifying details. A barcode scanner uses a light source and photosensitive sensor to read the barcode's information.
