Barter is a system of exchange where goods and services are traded directly for other goods and services without using money. This method allows individuals or groups to obtain what they need by offering something they have in return. For example, a farmer might trade a bushel of apples for a pair of shoes from a cobbler. Bartering has been used throughout history and is still practiced in some communities today. It can be beneficial in situations where currency is scarce or when people want to avoid using money. Modern technology has also led to the rise of online barter platforms, making it easier for people to connect and trade items.
