A handheld scanner is a portable device used to digitize physical documents, images, or barcodes. It allows users to quickly capture information by scanning items directly, making it convenient for tasks like archiving, inventory management, or data entry. Handheld scanners often connect to computers or mobile devices via USB or Bluetooth for easy file transfer. These scanners come in various types, including barcode scanners for retail and document scanners for office use. Many handheld scanners feature built-in memory, allowing users to store scans temporarily before transferring them. Their compact size makes them ideal for on-the-go scanning needs.
