fiat money:
Money which has no intrinsic value and cannot be redeemed for specie or any commodity, but is made legal tender through government decree. All modern paper currencies are fiat money, as are most modern coins. The value of fiat money depends on the strength of the issuing country's economy. Inflation results when a government issues too much fiat money.

Loss of backing
A fiat-money currency generally loses value once the issuing government or central bank refuses to further guarantee its value, but this need not necessarily occur. For example, the so-called Swiss dinar continued to retain value in Kurdish Iraq even after its legal tender status was withdrawn by its issuer, Iraq's central government.
Monetary economics
In monetary economics, fiat money is an intrinsically useless product, used as a means of payment. In some micro-founded models of money, fiat money is created internally in a community making feasible trades that would not otherwise be possible, either because producers and consumers may not anonymously write IOUs, or because of physical constraints
