The technical definition for a barcode is a machine readable form of information on a scannable, visual surface. The barcode is read by using a special scanner that reads the information directly off of it. The information is then transmitted into a database where it can be logged and tracked. Each number on a barcode has a special meaning, and often these numbers are added, multiplied, and divided in some formula that gives them each their own special individuality. Barcodes are very useful for maintaining accurate information about inventory, pricing, and other important business-related data. But in truth a barcode is so much more. Barcode systems help businesses and organizations track products, prices, and stock levels for centralized management in a computer software system allowing for incredible increases in productivity and efficiency. The lines and patterns on a barcode are actually representations of numbers and data and their development allowed basic information about a product to be easily read by an optical scanning device, a barcode scanner, and automatically entered into a computer system. This vastly reduced the time it took to record such information and eliminated the potential for human data entry error.
Over two million companies globally, including all major manufacturers, retailers, and online marketplaces use barcodes making it the defacto standards for the retail industry today. This is because they know that barcodes can help them improve their business. Some of the benefits of using barcodes are:
Provides unambiguous & universal identification of products so no two products in the world would have the same barcode number.
Helps with faster listing of products on e-commerce platforms.
Meets prerequisite to doing business with modern trade retailers.
