Token money, or token, is a form of money that has a lesser intrinsic value compared to its face value. Token money is anything that is accepted as money, not due to its intrinsic value but instead because of custom or legal enactment. Token money costs less to produce than its face value. A banknote, e.g. a five-pound note, is token money because despite its value being 5 pounds it only costs significantly less to produce. A gold coin is not considered token money. The Token money system has been adopted in many businesses around the world as an effective way to exchange value between companies and customers. Token money as a system is predominantly used in mobile games, but is also used in the realm of e-commerce. Token money is similar to fiat money which also has little intrinsic value, however they differ in that token money is a limited legal tender. The adoption of token money has improved transaction efficiency, as the practicalty of transacting with sums of gold poses a larger security risk. In a commodity economy, money is a measure of the value of goods and services (prices) within a sovereign country or the same economy, as well as a particular commodity to pay off debts. The token is also used as a medium of exchange, as a store of value, and as a unit of account. Digital currencies using decentralized blockchain technology are also a form of token money.
