What is a barcode?
A barcode is a graphic depiction of an item's unique identifier. It's made up of bars, which are parallel black lines.
Optical scanners can read the width of each bar and the space between them. If you have a barcode system in place, you can scan things to instantly add their information.
A barcode is a picture of parallel black and white bars that a barcode scanner can read. Products are labeled with barcodes so that they may be identified immediately. Barcodes are commonly used in retail businesses as part of the purchasing process, in warehouses to track and manage inventory, and on invoices to assist with accounting, among other things.
