I'm looking for a European alternative to Visa/Mastercard that works across countries, not just in one country. I know there's this https://en.wikipedia.org/wiki/European_Payments_Initiative but I believe it's not operational atm.
I hope the new attempt you linked will make a difference. This time, international support seems to be at the basis of the system. Widespread integration of a unified form of iDeal/Bancontact/Payconiq could easily replace the need for American style credit card forms across Europe.
