And while all the above payment methods are underpinned by accounts held in traditional currencies, let's not forget the rise of alternatives such as Litecoin. Such virtual currencies can rise in value very quickly, but are also susceptible to crashes and threats from hackers. Who knows, perhaps something totally new will take off that changes money as we know it? One such possibility is explored in the movie In Time. It imagines a futuristic society in which the currency is time itself, where people trade the amount of time they have left to live.
Or perhaps we'd do better to wind back the clock to the simpler financial world of the barter economy. While the term conjures images of sacks of grain and herds of sheep being exchanged in ancient times, there are signs that bartering is making a comeback in today's world of modern technology. Startup Let's Barter India has developed an app which facilitates the exchange of goods, and already has around 100,000 members.
Maybe the only thing we know for certain is that money will keep evolving.
