Morsal Hi 👋,
Bunq Credit Cards are linked to any of your sub accounts. The same happens for Debit Cards.
At bunq you do not charge any card. What you can spend needs to be on the linked sub account.
So the same for virtual Credi Card.
The difference between Credit and Debit is only from the vendor side so that you can for example make the security deposit for a car rental or hotel.
Here more info on official bunq doc:

Might good to remember that anything you want to charge to any bunq Card needs to be available on the sub account.
Bunq does not offer credit limits or loans.
I hope this helps 🙏
Cheers
GG
