Not sure Wero will succeed, but European country-specific mobile payment systems like Swish (Sweden), Vipps (rest of Scandinavia), Bizum (Spain), iDeal (Netherlands), Bluecode (Germany and Austria), Twint (Switzerland), BLIK (Poland) etc. are also working on interconnectivity under the EMPSA association. Combined they already have 110+ million users.
Wero is like a monolith, while EMPSA is more like mobile phone roaming. If I would bet, I would bet on EMPSA.

We wouldn't even need these services if instant payments were the norm. I guess we have to thank the Visa and MasterCard lobbies for this to happen at least 10 years too late.
Wero is iDeal.
In Austria EPS is also very commonly used.
Like sepa, this initiative can be forced by law and made open rather than tanken hostage by large cooperates, which may then exclude parts of the market.
