Currency refers to a medium of exchange for the supply of goods and services. In a nutshell, it is money in paper or coins that are usually issued by a government and mostly accepted as a payment mode at its face value.
Currency in any form is as old as at least 3,000 years. Money, generally in the form of coins, proved to be critical for trade facilitation across the globe.
In the 21st century, the virtual currency is a new form of currency which has entered the vocabulary. Virtual currencies, traded and stored in an electronic form, such as the bitcoins or the litcoins, do not have physical existence or government support.
A key feature of modern money is that it is uniformly insignificant in itself. That is, bills are bits of paper instead of coins made of gold, silver, or bronze. The idea of using paper as a currency was developed in China around 1000 BC, but it took a long time to receive a paper in return for something of real value, before coming into prominence. Modern currencies are published on paper in various denominations, with fractional copies in the form of coins.
