What it means to you, as an individual?
The PSD2 makes it possible to do more with payment data. For the PSD2, consumers were dependent on what a bank offered in terms of services. New possibilities, unfortunately with risks for your privacy.
When you purchase a service from an 'account information service provider', they will receive, after your consent, all of your payment details. The PSD2 does not offer the possibility to filter payment details. Even if a provider does not need all the data. You are then dependent on how that provider handles your data. It concerns as much data as you can access at your own bank, sometimes up to ten years ago. Some payment details you would rather not share. That must be your choice.
The Don't-PSD2-me-register should give you control over your payment details. At this stage we are working on a register containing account numbers that must always be filtered. These are the account numbers that, according to the privacy law, can be considered as 'special personal data'. Our goal is that you will eventually be in complete control of your data.
