Hey Jan Willem 👋
The possibility to transfer the address book from you previous bank to bunq sounds indeed like a handy feature for new bunq user! 🌈
I'll mark this topic as an idea 💡, although I'm not sure how technically feasible this is. Because all bunq probably have a own way of managing and storing your address book, I don't think there is a universal standard. And the address book is a part of the closed system of the other banks, but maybe PSD2 will open this up. Although I'm not sure on that one.
For now, have a nice day! 😄
