A portable scanner is a compact device designed to digitize physical documents, photos, and other materials. It allows users to quickly convert paper into digital files, making it easier to store, share, and organize important information. Many portable scanners are lightweight and battery-operated, enabling users to scan on the go without needing a power outlet. These scanners often connect to computers or mobile devices via USB or Bluetooth, allowing for seamless file transfer. Some models come with built-in memory, while others require an external storage solution. Portable scanners are popular among professionals, students, and anyone needing to manage paperwork efficiently.
