A barcode assists in automatic data collection and identification. A barcode scanner can easily read the information available on the barcode. Barcode scanners are stationary and hand-held devices used for reading the information, which is contained in the barcode. These scanners are joined to the computer by means of any kind of port. Scanners can’t perform calculations but can only capture barcode into numbers or letters. Barcode scanners comprise of a decoder and code reader.

The code reader throws the light on the barcode and then measures the wavelength of light, which is returned back by a barcode. The scanner then converts the generated light energy into the electrical energy and then this electrical energy is transformed consequently into the data in a computer.
