Scanners are devices used to convert physical documents, photos, or objects into digital formats. Scanners are available in several types, including flatbed scanners, sheet-fed scanners, and handheld scanners, each suited to different types of tasks. They are commonly used in offices, schools, and homes for archiving documents, creating digital copies of photos, or scanning receipts. Many modern scanners also come with additional features such as OCR (optical character recognition), allowing scanned text to be converted into editable files. Shopping online for scanners offers a variety of options, from high-resolution models to compact, portable devices for on-the-go scanning.
