Make the virtual cards as an image of a card (with name, number, expiry date) inside the app, so that when we have to add the card details somewhere (inside a payment app), that we are able to scan (photograph) them easily just like a 'normal' card would be scanned (so we do not need to input all those details manually every time and for each app).
I know, I am lazy... that is one of the perks of someone with a bunq of ideas :D
