What is a Bar Code?

Everyday you see bar codes in the world around you. You see them in supermarkets, on labels, greeting cards and consumable goods. By now you also realize that bar codes have replaced the traditional pricing of products.

Bar codes can be used in every business around the world. For example:

• To track assets in any building including every desk, computer, telephone, copier and desk accessory.

• To track mail from the time it arrives in the mail room to the time it is delivered to each desk or location within an office.

• To help security guards identify every employee, every door they enter and every room they work in.

• To secure, lock or unlock entrances or exits throughout the plant.

• To manage and track your vehicle fleet and each driver

A bar code can best be described as an "optical Morse code." Series of black bars and white spaces of varying widths are printed on labels to uniquely identify items. The bar code labels are read with a scanner, which measures reflected light and interprets the code into numbers and letters that are passed on to a computer.

With the expansion of global trade and computerization, plain language descriptions of products and services need to be replaced by identification systems that are usable in all trade and industry sectors world-wide.

Bar code system has been developed to meet this need by providing solutions that guarantees unique and unambiguous identification. Manufacturers, exporters, importers, hospitals, wholesalers, retailers, etc. can use the system to communicate information regarding the goods or services they trade.

These unique identification numbers can be represented by bar code symbols. This enables inexpensive and accurate data capture thus providing the required information at all points of the supply chain.

One of the main concepts of this system is that any item (product or service) upon which there is a need to retrieve pre-defined information and that may be priced or ordered or invoiced at any point in any supply chain can be allocated a unique identification number - the Global Trade Item Number, or GTIN for short.
