A barter system is an ancient method of exchange where people trade goods and services directly without using money. For example, if a farmer has apples and needs bread, they can offer apples to a baker in exchange for bread. This system relies on mutual agreement about the value of the items being exchanged. Bartering can occur on a small scale, like between individuals, or on a larger scale, such as between businesses. It is often used in communities where currency is scarce or in times of economic crisis. Barter systems can also be facilitated through online platforms, connecting people who want to trade their goods and services.
