A barcode is an optical machine-readable representation of data, which shows the relevant data about the material to which it is attached or fixed. With the help of bar code, the information can be assessed automatically, quickly and accurately. It is the fastest means of gathering data and can be generated easily and inexpensively by using state to art technologies. They can be printed dot-matrix, laser, and thermal transfer printers depending on the quality and demand. Thermal printing i.e. direct and ribbon-less, is comparably more consistent and generates clear image compatible with latest scanning technologies.
