You can use the TWAIN and OCR Engine provided through the LEADTOOLS SDK to scan a paper through a scanner, and then display the information in your application. After scanning your document, you can get access to the scanned image of your document through the TwainAcquirePageEventArgs Image property, and then pass the image you will receive into the IOcrPageCollection AddPage method which will allow you to read the information. You can try building on the following code for this:
private   void  Form1_Load(object sender, EventArgs e)    {        _viewer =  new  ImageViewer();        _viewer.Dock = DockStyle.Fill;        _viewer.BackColor = Color.DarkGray;        Controls.Add(_viewer);        _viewer.BringToFront();    }         // This will start the TWAIN session     private   void  acquireImageToolStripMenuItem_Click(object sender, EventArgs e)   {   _session =  new  TwainSession();    _session.Startup( this .Handle,  "manufacturer" ,  "productFamily" ,  "version" ,  "application" , TwainStartupFlags.None);    _session.SelectSource(string.Empty);   _session.AcquirePage +=  new  EventHandler (_session_AcquirePage);    _session.Acquire(TwainUserInterfaceFlags.Show);   }   private   void  _session_AcquirePage(object sender, TwainAcquirePageEventArgs e)    {         // Set the scanned image in the ImageViewer         _viewer.Image = e.Image;  // Get and Set the scanned image to the viewer       using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))       {           // Start the engine using default parameters           ocrEngine.Startup( null ,  null ,  null , OcrRuntimeDir);               // Create an OCR document           using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument())          {              // Add this image to the document              IOcrPage ocrPage = ocrDocument.Pages.AddPage(e.Image,  null );  // Pass the Image for OCR to grab data             ocrPage.AutoZone( null );  // Auto Recognize          }       }    }     https://www.leadtools.com/help/sdk/v21/tutorials/dotnet-core-minimum-code-required-to-ocr-files.html https://www.leadtools.com/help/sdk/v21/tutorials/dotnet-winforms-acquire-an-image-from-a-twain-source.html
