If EPI / Wero reach a critical mass then hopefully this will change, as non-Eurozone countries will have a direct interest in making the local mobile payment solution accept the one used by an area of 350+ million people.

Then the EPI protocol could become the least common denominator and you might be able to use Vipps, Twint, Blik... in Sweden? I believe similar scenarios are happening in Asia around Alipay and UPI, for instance I think I can use the Korean Kakao Pay on a payment terminal in Japan, because both sides are compatible with Alipay+.
