This is the screen where you can enter the password to transfer your game to another device, if you haven't notice, the last line is especially important information:
It basically means that the game is stuck to the device that you have played on. It can't be deleted. I think you can still try your luck and email Square Enix with an explanation that you are selling or trading your device but they may or may not entertain such requests as they have already stated so.
I understand that they want to prevent people from creating their own referrals or transfer cards around, but I think there has to be a better way other than locking the game into your device. Even the One Piece AR Carddass Formation game has a delete save data option although I have not tried it yet. To all those who spent a bomb in the game, take note!
