2032 heralded a new era for our currency, as more than half of the world's countries converted to electronic money systems. Although the new systems were cheap and efficient, problems began to occur...people outside the systems began to suffer. Attempts were made to include the minorities, but unfortunately this led to the system being hacked. Hyperinflation swept the globe and money needed to be made tangible once again. Nanotechnology allowed the redox flow battery to dramatically reduce in size...allowing people to carry a few kilowatt hours of electricity with them; exchanging charged electrolyte for goods is now a widespread reality and because energy cannot be created or destroyed only converted...the risk from hackers is negligible.
