A barcode scanner works by directing a beam of light across the barcode and measuring the amount of light that is reflected back. The dark bars on the barcode will reflect less light than the white spaces between them. The scanner then converts the light energy into electrical energy, which is then converted into data by the decoder and forwarded to a computer.
