Is There a Cashless Society in Europe?

I'm a modern digital person. I don't carry cash. I pay on my smartwatch is the way that I tend to pay most of the time. And I also believe it is important that we protect cash because there are many people who struggle with plastic, can't remember pin numbers and have other issues. So I am signed up to the campaign for protecting cash, even though I don't use it myself. But I do think society does and has to adapt.
