It seems to me that in country blik is using a joint company wherein the banks have stake, as well as Mastercard has a stake. Outside of Poland Mastercard is the "transport layer" so to say.
If then Wero wants to be an implementation of this lower-lever transaction network,thais is good news, as it can be probably integrated in parallel/addition to Mastercard when we have a falling out. But it's not the impression that I hot from the website- to me it appeared as a consumer application.
But what instead? Spanish? German? Esperanto?
