Bastiaan I have my business account with Bunq . When the finance company saw that, it was indicated that I have to specify another account (different bank). According to the employee, I could change back to the bunq account after acceptance. I don't know if that falls under iDin or has anything to do with it. It was indicated that it has to do with the lack of personal identification. At other banks you must identify yourself personally when opening an account.
