A mobile app for scanning documents provides a simple and efficient way to digitize physical documents using a smartphone or tablet. These apps utilize the device's camera to capture high-quality images of various paper-based materials, such as documents, receipts, and business cards. They often include features like auto-cropping, text recognition (OCR), and cloud integration, making it easy to organize, share, and store digital copies. Ideal for personal or professional use, they streamline the process of going paperless.
