What to do if 3DS authentication fails?

If the 3Ds authentication fails then PSP must update the authorization attempt with "suceeded: false" to indicate that the authentication failed. 

As soon as PSP update the authorization attempt with “false” and a reasonCode that is not 1008 or 1009, then the web view will close. The user will then see the accept screen again and can try with a different card. This means that PSP do not need to redirect the user to the done3ds page as usual after a succesfull authentication. 

The user can then try with a new card which will result in a new callback to PSP, either a token og pan callback depending on the card.
