Money is anything that is widely accepted as a form of payment for goods and services or repayment of debts. In the limited economies of POW camps, cigarettes became money as soon as they became the accepted form of payment for rations that prisoners were exchanging. In developed economies, such as the United States, the use of commodities as money has been replaced with paper currency endorsed by the government, along with coins minted under
government direction and electronic deposits facilitated by banks. No matter the size of an economy, money facilitates transactions between buyers and sellers.
