I totally agree with the op, cashless society can only work if the entire world is well developed in a way that both the young and old have access to the internet and can also operate computers and smart phones easily, taking my country for example, there are several of our fathers and mother here who don't even know what a mobile phone is before we being talking of know how to communicate using mobile phone, if the society decides to go cashless now, how this this set of forks be able to buy and sell,?? This is one of the reasons why I think that cashless society is still very far away.
