```
public final class CheckScannerFrameHandler
extends FrameHandler
                    
```
Performs check data scanning on camera preview frames. Outputs results via CheckScannerFrameHandler.ResultHandler (.addResultHandler).
Preview frame considered intercepted if at least one CheckScannerFrameHandler.ResultHandler returns true from CheckScannerFrameHandler.ResultHandler.handle (FrameHandlerResult)}

    previewFrame - captured preview frame data
  - addResultHandler
```
 final Unit addResultHandler(CheckScannerFrameHandler.ResultHandler handler)
```
    Registers result handler which will be notified about check data detection results.

    Returns the frame in the scanning result on success.
    
    Parameters:
    
    returnFrameOnSuccess - if true camera frame will be returned in the scanning result, false - otherwise The default value is FALSE.
  - attach
```
 final static CheckScannerFrameHandler attach(IScanbotCameraView cameraView, CheckScanner checkScanner)
```
    Convenience method for creating new CheckScannerFrameHandler and adding it as FrameHandler to given camera view.
    
    Parameters:
    
    cameraView - camera view to which new check data detector will be attached
