Barcode Scanner
A **barcode scanner** is a device that reads and decodes barcodes, which are graphical representations of data. It uses light to scan the barcode and converts the pattern into readable information, such as numbers or text. Barcode scanners are commonly used in retail, warehouses, and healthcare to quickly and accurately capture product information, streamline transactions, and manage inventory. They can be handheld or fixed, and come in various types, including laser and image-based models.
