In trade, barter is a system of exchange in which participants in a transaction directly exchange goods or services for other goods or services without using a medium of exchange, such as money. Economists usually distinguish barter from gift economies in many ways; barter, for example, features immediate reciprocal exchange, not one delayed in time. Barter usually takes place on a bilateral basis, but may be multilateral. In most developed countries, barter usually exists parallel to monetary systems only to a very limited extent. Market actors use barter as a replacement for money as the method of exchange in times of monetary crisis, such as when currency becomes unstable or simply unavailable for conducting commerce.
A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.

A local exchange trading system is a locally initiated, democratically organised, not-for-profit community enterprise that provides a community information service and records transactions of members exchanging goods and services by using locally created currency.

A virtual economy is an emergent economy existing in a virtual world, usually exchanging virtual goods in the context of an online game, particularly in massively multiplayer online games (MMOs). People enter these virtual economies for recreation and entertainment rather than necessity, which means that virtual economies lack the aspects of a real economy that are not considered to be "fun". However, some people do interact with virtual economies for "real" economic benefit.
A complementary currency is a currency or medium of exchange that is not necessarily a national currency, but that is thought of as supplementing or complementing national currencies. Complementary currencies are usually not legal tender and their use is based on agreement between the parties exchanging the currency. According to Jérôme Blanc of Laboratoire d'Économie de la Firme et des Institutions, complementary currencies aim to protect, stimulate or orientate the economy. They may also be used to advance particular social, environmental, or political goals.

The Chiemgauer operates with a fixed exchange rate, tied to the value of the euro: 1 Chiemgauer = €1.
A private currency is a currency issued by a private entity, be it an individual, a commercial business, a nonprofit or decentralized common enterprise. It is often contrasted with fiat currency issued by governments or central banks. In many countries, the issuance of private paper currencies and/or the minting of metal coins intended to be used as currency may even be a criminal act such as in the United States. Digital cryptocurrency is sometimes treated as an asset instead of a currency. Cryptocurrency is illegal as a currency in a few countries.
Demurrage is the cost associated with owning or holding currency over a given period. It is sometimes referred to as a carrying cost of money. For commodity money such as gold, demurrage is the cost of storing and securing the gold. For paper currency, it can take the form of a periodic tax, such as a stamp tax, on currency holdings. Demurrage is sometimes cited as economically advantageous, usually in the context of complementary currency systems.
The WIR Bank, formerly the Swiss Economic Circle, or WIR, is an independent complementary currency system in Switzerland that serves businesses in hospitality, construction, manufacturing, retail and professional services.

Virtual currency, or virtual money, is a digital currency that is largely unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community. In 2014, the European Banking Authority defined virtual currency as "a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically." A digital currency issued by a central bank is referred to as a central bank digital currency.

The Future of Money: Beyond Greed and Scarcity is a book written by Bernard Lietaer, published by Random House in 2001, and currently out of print. It was written as an overview of how money and the financial system works, the effects of modern money paradigms, especially relating to debt and interest, and how it can work to everyone's benefit to solve a wide range of problems, especially with the use of complementary currencies. The book is meant to be written for the layperson, while bringing light to subjects that only relatively few are aware of at all levels of society.

The Community Exchange System (CES) is an internet-based global trading network which allows participants to buy and sell goods and services without using a national currency. It may be described as a type of local exchange trading system (LETS) network based on free software. While it can be used as an alternative to traditional currencies such as the Australian dollar or euro or South African rand, the Community Exchange System is a complementary currency in the sense that it functions alongside established currencies.
