Hans While I have no information on whether or not bunq is working on more PSP features, judging from their current product portfolio, to me it doesn't seem like this is an area where they want to expand to soon. However, there is no need to switch banks just to accept SDDs from your customers. Companies like Mollie and many more offer cheap and reliable payment solutions exactly for this case, and the money will end up in your bunq account. Maybe that's something you want to look into!
