Not sure how complex it is to set this up, but I really like the behaviour of Curve in terms of being able to carry one card and moving transactions between different cards.
Could Monzo adopt similar behaviour for those of us that have a current account and a joint account? And perhaps eventually for spending from pots as well? It would be great to have one Monzo card to rule them all and be able to spend from my different accounts with that.
Sorry if this has already been suggested!
