Maleene marcel Here's something you can do, but it's not completely foolproof: Take your bunq.me link and modify it before sending by adding some information:
https://bunq.me/<example_name>/<amount>/<description>/<method>
Let's say you want 12.50 Euro from a friend for some pizza who is not using bunq, but is from the Netherlands and is using another Dutch bank, then you send them:
https://bunq.me/example/12.50/Pizza/ideal
Or if you want 50 Euros from a German friend for taking all your home-made stroopwafels while you were asleep:
https://bunq.me/example/50/Reparations/sofort
etc. you get the gist. With this you can send everyone automatically to the right place. Of course, people could still manually change the link if they know how bunq.me works. And it's more effort. But maybe useful in certain situations.
