Paper money is good but its old and not as much as helpful like electronic money . You can access and use your electronic money in anywhere you want to use with simply taking  help of Internet. In this Morden world everyone wants to go cashless while they go for shopping, no one wants to carry an bundle of paper note with them and in this case electronic money help them. Even in many countries their government encourage people to use more and more electronic money. So in my opinion paper money has a future but not for long time.
