Buying things today is so simple. Just enter a shop, say a book store, choose the desired book and pay for it. Long ago, before the invention of money, how did people trade?

The most primitive way of exchange should be the barter trade. In this form of transaction, people used goods to exchange for the things that they had in mind. For instance, if person A wanted a book and he had a spare goat, he must look for someone who had the exact opposite, that is, that someone, say person B, must have a spare book of person A's choice and is also in need of a goat. Having found such a person, the problem does not end here. A big goat may worth not only one book, hence person B may have to offer person A something else, say five chickens. However, he runs the risk of person A rejecting the offer as he may not need the chickens. The above example clearly illustrates the inefficiency of barter trading.

Many years later, the cumbersome barter trade finally gave way to the monetary form of exchange when the idea of money was invented. In the early days, almost anything could qualify as money: beads, shells and even fishing hooks. Then in a region near Turkey, gold coins were used as money. In the beginning, each coin had a different denomination. It was only later, in about 700 BC, that Gyges, the king of Lydia, standardized the value of each coin and even printed his name on the coins.

Monetary means of transaction at first beat the traditional barter trade. However, as time went by, the thought of carrying a ponderous pouch of coins for shopping appeared not only troublesome but thieves attracting. Hence, the Greek and Roman traders who bought goods from people faraway cities, invented checks to solve the problem. Not only are paper checks easy to carry around, they discouraged robbery as these checks can only be used by the person whose name is printed on the notes. Following this idea, banks later issued notes in exchange for gold deposited with them. These bank notes can then be used as cash. Finally, governments of today adopted the idea and began to print paper money, backed by gold for the country's use.

Today, besides enjoying the convenience of using paper notes as the mode of exchange, technology has led man to invent other means of transaction too like the credit and cash cards.  

Summary: Long ago, people bought things through barter trade. However, the difficulty of having to look for the right partner and dividing the goods led people to switch over to monetary transaction. at first, beads, shells and fishing hooks were used as money. Near Turkey, gold coins with irregular denominations were used for trade. Later, King Gyges standardized the individual coin value. People soon found carrying coins around for shopping troublesome and thieves courting. Hence, merchants started to issue checks with names of the users on them to discourage robbery. Following that, banks started to issue cash notes in return for gold deposited with them. Finally, adopting the idea, today, governments printed paper money backed by gold for the country's usage.
