Always kinda liked the design of the joint cards for Simple Bank (US) in that they’re split.
Just thought I’d try out what it would be like if Monzo did this, but even better, had complementary (reversed) colouring for each person:
But… I can only imagine the hassle this would cause customer service when someone loses a card (“so is your card the yellow/pink or pink/yellow?”) 
I think this looks really good! I like the “Monzo Joint” type in keeping with the Plus cards. Really like the idea of mirrored cards pink/blue blue/pink or whatever
Thanks! I do worry that Monzo are neglecting the Joint accounts a teeny little bit… I know they’ve got a lot of things to concentrate on as Monzo is growing at a fast rate (which is great!) but I think joint accounts should have as close feature parity to standard accounts as possible.
Agreed. But gimme features over fancy cards first 
It’s a good concept and a nice design but from another side, I don’t know if I want an extra card in my wallet.
I would prefer an option in the app that allow me to choose between my personal account and the joint one. Especially because most of the time I use Google Pay or I don’t have my wallet with me.
Great concept, love the designs - I think you’re on to something here. 
I think the idea of the reversed colours on each card works really well 
Love it! But never going to happen since Monzo simply don’t care about their joint account holders. They are just second class
This would be great!!
