As part of the new Payment Services Directive PSD2, ING has revised its online banking. The account data retrieve will no longer be done via HBCI but by Screenscraping.
Therefore, payments via HBCI are no longer available.
On its website, ING explains that they “misjudged the importance of accessing the HBCI interface for our customers and the effort involved in integrating the 2-factor login. Therefore, for the foreseeable future, we will not be able to make the HBCI interface fully PSD2 compliant.” (full explanation of ING in German: https://www.ing.de/kundenservice/sicherheit/psd2/#8762904)
