Barcode technology is a method of encoding information in a visual format that can be easily scanned and read by machines. It typically consists of a series of parallel lines and spaces of varying widths, which represent data such as product numbers or prices. This technology is widely used in retail, inventory management, and logistics to streamline processes and improve accuracy. When a barcode scanner reads a barcode, it converts the visual information into digital data that can be processed by a computer system. This allows businesses to track products, manage stock levels, and speed up checkout processes, enhancing overall efficiency and customer experience.
