Dd is fourteen and pretty mature and responsible. She has to start taking a (public) bus to school this month and rather than relying on her remembering to take cash/ debit card or buying her ticket online (and inevitably forgetting to do that) I thought about adding a debit card to her Apple account so she could pay for bus pass with her phone. I guess it would also be useful for emergencies too.
Has anyone done this? Am I missing anything obvious?!
