There is a drastic change in inventory management, which was brought by the introduction of the barcode scanners. Barcodes are used by both small and large organizations and small stores to record items and facts which are necessary to maintain the stocks in business.

Barcode has the information about the product or item. That information can be read by the barcode scanner and it can decode it into a version, which humans can recognize.

There are vertical lines and spaces among them which form a unique id, it is also called as barcode. Thickness, along with the spaces between the lines and bars, determine the recognition. Later barcode data can be identified by barcode reader and it is shifted to the computer device. So it is necessary to computer to have the barcode scanning application to convert them into the letters and numbers to understand such data.
