Jeroen ๐ณ๏ธโ๐ Absolutely, although the places you go to of course do have to support contactless payments. If they don't, you still need a card: and that's where it get's tricky. However, as mentioned in another topic it looks like come may this year: all terminals in NL (in stores) must support contactless payments. So that solves a lot of problems (in the Netherlands anyway, dont know how contactless acceptance is in other bunq countries). And the physical cards I guess you can then just share whoever needs it when they go abroad... Although that'll be tricky if you don't live near each other. :P
Incidentally, I think this would work even better if you activate a Tap&Pay card. You can actually add that to Apple Pay and Google Pay as well in supported countries, and if the card got a supported region when it was generated. That card is 100% virtual Maestro and does not count towards your total amount of cards. That's an ideal card to have for this Joint Subscription, and if I understand the OP correctly: everybody can create 5 online MasterCard's and has all advantages such as Google and Apple Pay - so I imagine that includes being able to generate a virtual Tap&Pay Maestro as well. Then you don't even have to use the same cards with Tap&Pay/Apple/Google Pay, everybody can just put their own T&P in there.
