no no an no. any physical cards no matter the material is a bat ideal, plastic is bad for the environment, metal is even worse, the future of payment is in mobile devices and so called wearables through Google/Apple/Samsung/Fitbit/Garmin Pay or Android Tap & Pay, since bunq update 6 or 7 in the spring of last year I've been using Apple Pay almost exclusively and don't even touch those card anymore (or only when needed). They are a waste of earths resources, bunq in my opinion, should become the first bank to stop issuing physical cards altogether and go with digital, virtual-only provisioned cards in the mobile wallet solutions from the major manufacturers as mentioned above.
Otherwise, bunq might as well make their cards from bamboo for all i care π€£
