The processing of special personal data is in principle prohibited. From payments to organisations, membership of a political party, trade union, someone's health, sexual behaviour or orientation or philosophy of life can be deduced. As soon as a consumer uses a PSD2 account information service provider, this can be disclosed. The PSD2 does not offer the possibility to prevent this. Do you know what a PSD2 provider or profiling company can do with this information?
