A Document Scanner is a device that converts physical documents into digital format. It captures the text and images on paper and creates a digital file, such as a PDF or JPEG. This process allows for easier storage, sharing, and editing of documents, making it a valuable tool for both personal and professional use. Many modern document scanners come with features like automatic document feeding, duplex scanning, and optical character recognition (OCR). These features enhance efficiency and accuracy, allowing users to quickly digitize large volumes of paperwork. Popular brands include Canon, Epson, and Fujitsu.
