alt Hacker NewsSweden has a similar "initiative" set up by a consortium of banks (Swish), as do many other European countries.
Usually these systems raise their fees after being established, sometimes even higher than Visa/Mastercard.
Brazil's Pix is something else. It wasn't created by private entities to make money.
Wero's Dutch predecessor, iDEAL, has been an established part of online payments for 20 years now.
As barely anyone has a credit card and very people want to deal with the faff of manually entering billing codes or account numbers, iDEAL usage is near universal for online payments. I don't recall fees ever going up as an end customer.
