Hi @Martijn 👋,
In addition to @W. Janson, I remember a similar topic were Ali responded that bunq did looked into a metal card 💳.
I quote @Ali "We looked at the metal passes a long time ago and decided not to do so. This is because the passes are so incredibly environmentally unfriendly that they do not suit us well. Moreover, there is still some hindrance in daily use (breakage, scratching, etc)." (original post was in Dutch).
But, there is a workaround... I pay 99% of the time with my phone 📱... so, I am paying already with a metal card if you think 🤔 about it 😜.
Nevertheless, I would love to have a card the famous bunq colors but with a more Premium feel. And you did a great job on the mockup 👍
