The processing of personal data revealing anything sexual behaviour or sexual orientation is in principle prohibited. The preferences of an individual can be deduced from payments to advocates, in certain locations or to certain shops or persons. As soon as a consumer uses a PSD2 account information service provider, this can be revealed. The PSD2 does not provide an opportunity to prevent this. Do you know what a PSD2 provider or profiling company can do with this information?
