This is something that have always intrigued me. Everyone that knows would agree that none of the countries that constitute the Eurozone is the same. Especially if one were to consider the different payment solutions and customer orientation towards these, one observe massive differences. Some countries are still heavily dependent on cash payments, while others have installed sophisticated PIN-based payment systems. In some it is acceptable to do Internet payments and in others cheques are still in circulation.Especially, if one were to consider mobile payments, differences are even more distinct. Initiatives in Nordic areas are not at all comparable to what is happening in Austria nor some of the great work happening in the Iberia peninsula. The challenges regarding money supply and cost of doing business are all different from one country to another.
So here is my question: "How can you regulate all these different countries with the same banking regulation?"
