What is Bar Code?
A bar code (or barcode) is a method of representing data in a visual, machine-readable form. Initially, bar codes represented data by varying the widths and spacings of parallel lines. These are called linear or one-dimensional (1D) bar codes. Later, two-dimensional (2D) codes were developed, using rectangles, dots, hexagons and other geometric patterns in two dimensions. Bar codes are commonly used to track inventory, identify products, and scan items at points of sale.
