I believe this will happen. The world is moving from paper reliance to paperless systems. Usually, utility bills and other periodical bills give the customers option to get their bills via email or other electronic copies. This is the case also in online purchases. They usually just give the customers a copy of the receipts and other documents via email.
But it will happen in so many years, Because we are in the high technology are already used by almost people and maybe for the purposes of their online transactions only. But i think its not easy for them to create their own cryptocurrency, because they maintain their fiat.
