I just switched to Premium and enabled Tap & Pay. Can't wait to try it out!
Since I've got two "cards" now (three when my MasterCard arrives), and they're both linked to the same account, it says "bunq card (08/21), bunq card (05/21)". I know it's technically correct, but I've got to say this won't help me determine what card is linked to which account, especially at first glance :P
Also, my MasterCard will have the same expiration date as Tap & Pay, so it will be impossible to tell them apart.
Would it be an idea to introduce in-app nicknames for your different cards? That way you can easily tell them apart. Or at least showing which card is which, like "Maestro (05/21)". That should help clear things up :)
