A bar code reader scanner captures the pattern in a barcode and sends it to the computer, where special software translates the pattern into meaningful data.
Explanation:
A barcode reader is a handheld device that captures and reads information that is contained in a bar code. It consists of a scanner, a decoder and a cable that connects the barcode reader into a computer. This scanner works by directing a beam or red light across the black and white elements of a barcode. This amount of light energy that is reflected back is measured and converted into electrical energy which is then converted into readable data by the decoder and forwarded to a computer.
