A code consisting of a group of printed and variously patterned bars and spaces and sometimes numerals that is designed to be scanned and read into computer memory as identification for the object it labels. Each of the digits zero through nine are represented by a different pattern of bars that can be read by a laser scanner. The bars are commonly found on consumer products and are used especially for inventory control. A barcode is a machine-readable symbol used to encode information in order to automate a business process. Examples of business processes are retail sales, shipping and tracking, inventory management, warehouse management, asset tracking, and automated data entry.
Use of Barcode
In recent years, nearly all the products one finds in the shops are managed
through the use of barcodes.
These barcodes are a form of coded information: all the
data pertinent to the products are compressed within them. In other words, this
coded information called barcodes have an equal value to the products
themselves. we usualy get barcode in book as ISSN
number.
