The Future of Money

We can have spare cash, something that we don't really need. Many countries are gradually getting rid of some of the smaller kinds like half pennies or half a cent or 5 cents. And this brings into question whether society will actually use money at all. I visited a couple of years ago Sweden and I was in Stockholm and in many, many places they don't take cash at all. So, it's all about click and pay you know with your card,. You touch the machine and bingo it's deducted from your bank account even for small items like a coffee or a newspaper or something it's still click and pay and off you go.
