The history of bartering dates all the way back to 6000 BC.
A barter system is an old method of exchange. This system has been used for centuries and long before money was invented. People exchanged services and goods for other services and goods in return.
Under the system, there is no common measure of value.
If a society relies exclusively on perishable goods, storing wealth for the future may be impractical.
Barter may occur in commercial economies, usually during periods of monetary crisis.
It still occurs today, if you've ever swapped something you own with a friend in return for something of theirs, you have bartered.
