Warner You don't add money to a card, but to your bank account. Your bank account at bunq works much like a bank account at any other bank. If you have a balance on PayPal, then there's a button to withdraw to a bank account. Here fill in your IBAN from bunq. Then PayPal will transfer the money via bank transfer to your bunq account. Afterwards, you can use your bunq Mastercard to spend the money (or do something else with it, your call!)
