A document scanner is a device that converts physical documents into digital format. It captures the text and images on paper and saves them as files on a computer or cloud storage. This process makes it easier to organize, share, and store important information without taking up physical space. There are various types of document scanners, including flatbed scanners and sheet-fed scanners. Flatbed scanners allow users to place a document on a glass surface, while sheet-fed scanners automatically feed multiple pages through the device. Both types help streamline workflows in offices and homes by digitizing paperwork efficiently.
