What is a system in exchange in which products are traded directly for other products?

A system in which products are traded directly for other products is known as barter. In a barter system, goods and services are exchanged without the use of money, relying instead on mutual agreement regarding the value of the items exchanged. This method of trade can foster direct relationships between parties and is often used in situations where currency is unstable or unavailable. Bartering can be both informal and organized through barter exchanges or networks.
