Barcode Reader using reusable libraries

by Deepu

A barcode reader is an optical scanner that can read printed barcodes, decode the data contained in the barcode and send the data to a computer. It consists of a light source, a lens, and a light sensor translating for optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry that can analyze the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
