Defining currency, the latter is a kind of money launched and controlled by a particular state or a number of states in a certain geographical area. Currencies are usually official legal tender provided by a country’s government or the country’s central bank to promote the flow of economic activities and act as a medium of exchange, unit of measurement, and value storage within that country or area. Currencies include the dollar of the United States, the euro which is used by the European Union, the Yen of Japan, and the Rupees of India.
