EU forced MC/Visa to slash their intercharge fees to max 0.20%... that's why there is no "reward" program over here because we are not being ripped off constantly :)

What's more, said Bizum is the driving force behind ENP to integrate all those payment systems: https://epicompany.eu/media-insights/european-network-for-pa....
