Bar Code Scanner

A barcode scanner is a device that reads the information encoded in a barcode—a series of black and white lines or patterns—using a laser or camera. When you scan a barcode, the scanner converts the visual pattern into digital data that a computer can interpret. This process quickly retrieves product details, prices, or inventory information, making transactions efficient and reducing errors. Barcode scanners are commonly used in retail, warehouses, and logistics to streamline tracking and management of goods.
