Can only send money to other ppl who have it, waiting to be able to pay in online shopping with it

My bank (Rabobank, Netherlands) hasn't rolled it out yet, but it is planned for early 2026.

In theory, if I'm understanding correctly, it will be an in place replacement of the already existing iDeal payment system. So I wonder how much I will even notice of the change.

Can someone quickly introduce me to this tech? (Yes I am aware of the wikipedia article)

I had the chance to use it to send money to some friends, and it was very easy to use for that use case! (BTW the link to the wikipedia article is broken)

I have used Wero (my bank is ING) and it worked pretty well. Money was transferred really fast and uncomplicated.
