If you have scanned images that have barcodes and you need to read these barcodes using application software, you can use LEADTOOLS to read almost all common Barcode types with few lines of code: Leadtools.Barcode.BarcodeEngine engine = new BarcodeEngine(); BarcodeData[] barcodes = engine.Reader.ReadBarcodes(bitmapImage, LeadRect.Empty, 0, null ); //Display all barcode values found, if any for ( int i = 0; i { MessageBox.Show(barcodes[i].Value); } Once you get the barcode value, you can store that value in a text or other file format. For more information about barcode types see this link: https://www.leadtools.com/sdk/barcode If you mean that you want to read Barcode image using Barcode scanners handle device, see this topic https://www.codeproject.com/Articles/34473/Controlling-a-Barcode-Reader-with-POS-for-NET
