What Are The Disadvantages Of Bar Coding?

A bar code is a set of parallel printed lines with different thickness which is used to store coded information about a particular product. Bar codes are usually read with the help of hand held or stationary laser scanners over which a bar code is run. This form of data entry is used in places like large shops, supermarkets and in libraries. It is a very quick method of data entry and it eliminates human error. The disadvantage of bar codes is that scratched and crumpled ones cause way too much problem.

A barcode is a machine-readable illustration of information which is available in visual format on a surface. Initially barcodes use to keep data in the spacing of printed similar lines, but now days they come in the formation of dots, concentrating circles and hidden images.
