| == Usage ==
| |
| The setupcallbackhandler method will set a callback handler. Before calling this method, you should call the open method. After setting the callback handler, the default PINPAD UI will not pop up, the driver will send the inputing PIN count to the callback handler, then the third-app can process the inputing PIN count.
