A barcode scanner is a handheld or stationary device used to read and decode barcodes printed on products, packaging, or labels. It uses laser or imaging technology to capture barcode data and convert it into digital information for processing by computers or inventory management systems. Barcode scanners are essential tools in retail, warehousing, and logistics for tracking inventory, speeding up checkout processes, and reducing human error. They come in various forms, including wireless, wired, and mobile versions, each designed to meet specific operational needs. Durable and user-friendly, barcode scanners improve accuracy and efficiency in data collection and inventory control.
