What is Barcode?
A barcode is a method of representing data in a visual format that can be read quickly and accurately by a barcode scanner. It consists of a series of vertical bars of varying widths and spacings, which encode information such as product identification numbers, quantities, and prices. The most common type of barcode used today is the UPC (Universal Product Code), which is widely used in retail to identify products. Barcodes are used in a variety of applications, including retail, inventory management, and shipping, to improve efficiency and accuracy. The information encoded in a barcode is read by shining a light on the bars and measuring the amount of light reflected back. This information is then translated into a digital format, allowing computers and other devices to process and store the data.
