LvH A metal card that can last for 20 years would be very nice. And that they aren’t issued like that now doesn’t mean it cannot change
Physically maybe, depending on the choice of metal. But in terms of functionality, EMV bank cards contain cryptographic chips with very limited processing power. Their cryptographic properties and thus security will simply be outdated in 20 years.
I love metal products more than anyone else I know. I don't really feel the need for it in a bank card (which I'd rather prefer lightweight), but depending on price, I might even be tempted to get one.
As for the purported ecological and environmental advantages over regular "plastic" cards however, I think they are make-believe.
