I am very new to PowerApps, attached is the AI Builder Business Card Scanner, wherein once i click Save to Sharepoint, it should save the data to Sharepoint and then reset the form to blank, so that there will not be any confusion.
You can reset the business card reader by adding to the OnSelect action from your "Save to Sharepoint" button the following command: Reset("YourBusinessCardReaderComponent"). This will clean up the placeholder image and the properties of "YourBusinessCardReaderComponent".
There is currently a bug with the reset of the business card reader (the properties are no cleared up), but this will be fixed soon. In the meanwhile, you can set the form field values to an empty string also in the OnSelect action of the button as well.
