Explanation
The TransferMode property sets whether native, file, or memory transfer is used. The default value is 0 (ikScanNative). It is necessary to set this property prior to executing the Execute method. The possible transfer methods supported by a scan device can be retrieved using the GetCapEnumToFloat method. Scanning events are generated for the memory transfer mode only.
