It would be nice if there was a option to simulate card payments (Maestro and Mastercard) in de bunq sandbox environment. Like there is already https://txbank.bunq.com/ideal.php to simulate iDEAL top-ups and sugardaddy@bunq.com for requests.
I would like that! And I also would like to be able to assign cards to an accounts and to setup second pin, just to show it off to people. Activation of cards isn't a problem, but I can't assign them to accounts for some reason.
