As some one who comes from a country where tax evasion is common(India), I can tell you Greece's problems have just begun. And its not like introducing plastic money or online transactions will fix anything here. By now most of the Greeks would be so mentally conditioned to not paying taxes, any attempt from the government to make them pay will come across as a being handed out a very unfair deal. Most will feel cheated and being asked to make sacrifices out of their way. In fact this is the reason why its so difficult to turn around things in such countries. The issue is not technology or government policy. When you have a whole generation of people grow up in such a ecosystem, these practices seep into your culture and everyday life. You can only undo them gradually overtime, and sometimes it takes 2-3 generations to get out of it. Another defining characteristic of a society where cash transactions are common - Every day corruption is omnipresent.
