ReturnCheckDigit # get and set (GS1DatabarStackedBarcodeReadOptions)
Value indicating whether the error check digit is returned as part of the barcode data. The default value is Default.
If you set the value of ReturnCheckDigit to Yes, then this digit is returned as part of barcode data (can be retrieved with BarcodeData.GetData or BarcodeData.Value). Then parse the data and extract the error check digit from the rest of the data based on the barcode symbology standard.
