I would very much like to see the world as in films where people have chips and can pay for them. But probably not in our reality.
Well maybe it can happen in the future, we may never know what's gonna happen that time. But for the coming years I think this is still impossible to have a cashless society.
To me it is possible because as I have notice a lot of people are happy to have this cashless system of payment, digital currency is helping people to save money, now street robbing has been reduced and almost finish as no one can robe your bitcoin, it is easy to carry a lot of bitcoin but you cannot carry a lot of money with you, so coming age is going be cashless age and era of digital currency it will be.
