I’d really love to be able to create child ‘pocket money’ accounts linked to my main account. Each Pocket money account would have its own card controlled by the parent account and could be transformed into stand alone account when child hits 16/18. Parent can see all child activity, easily transfer funds and lock account.
In the cashless world we live no one offers this functionality today. Would probably also work with only virtual card that kids could add to their phone wallet. Kids have limited functionality app too.
