The barcode has a long and interesting history from its initial development nearly 70 years ago through today. However, today barcodes come in many shapes and sizes and a wide range of designs and many can even be read by mobile phones and other devices. This vastly reduced the time it took to record such information and eliminated the potential for human data entry error.īarcodes started out with simple 1-dimensional designs, consisting of basic black lines that could only be read by specially designed barcode scanners. 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.

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. What is a barcode ? A barcode is “A machine-readable code in the form of numbers and a pattern of parallel lines of varying widths, printed on and identifying a product.” But in truth a barcode is so much more. Yet barcodes play a crucial role in the effective and efficient operation of our economy, from small businesses to large multinational conglomerates. Every time we purchase something we interact with a barcode, but rarely do we give them much notice.
