Barter

Barter is a type of trade that doesn't use any medium of exchange, in which goods or services are exchanged for other goods and/or services. It can be bilateral or multilateral as trade.

Barter and money are different means of balancing an economic exchange. Barter is recognized as trade in societies without monetary systems. Although it can be argued that barter exists in most societies parallel to monetary systems. Barter crosses over to the spheres of trade with money when economies are suffering from a very unstable currency (as when hyperinflation hits). Barter is also used as a concept in regard of intercultural exchange between craftsmen or artists of different countries, especially when the exchange is passing the gap between "the rich world" and "the poor world".
