iDEAL supports banks to implement payment in their online banking websites

So does Wero, as I cited in another comment:

The Wero app is available only for account holders from the German bank Postbank and the French bank La Banque Postale.

Are you a customer of another Wero-enabled bank? If so, you can easily use Wero within your banking app.

It's not the same system.

I said that it is based on the iDEAL system:

Wero is built on the foundation of iDEAL, backed by 16 major European banks – including the Dutch banks behind iDEAL.

The European Payments Initiative (EPI) acquired the Dutch payment system iDEAL with the aim of making it the standard payment solution across all European countries. [...] The first step is to make iDEAL the standard in France and Germany because the countries don’t yet have a standard payment system for e-commerce, according to AD. Customers in the Netherlands will notice little of this.
