Bas Hey Bas 👋 Thanks for reaching out!
While this information isn't included in your bank statement, if there are specific transactions for which you wish to know the card number, you can reach out to support and request the information. However, Thijs is correct that for iDeal payments, there's no card involved, only an IBAN. Rabo may be able to provide this info if their cards are only linked to one account, but, owning to the flexibility of our multiple IBANs and budgeting capabilities, this is not the case with bunq.
Furthermore, if you'd like to make an official suggestion that our bank statements include this information, feel free to create a new Together post about and don't forget to add the "Ideas" tag so that other bunqers can voice their support 🙌
