根據(jù)下面內(nèi)容，回答題：

　　In ancient times wealth was measured and exchanged in things that could be touched: food,tools, and precious metals and stones. Then the barter system was replaced by coins, which still hadreal value since they were pieces of rare metal..Coins were followed by fiat money, paper notes thathave value only because everyone agrees to accept them.

　　Today electronic monetary systems are gradually being introduced that will transform money intoeven less tangible forms, reducing it to a series of "bits and bytes", or units of computerized informa-tion, going between machines at the speed of light. Already, electronic fund transfer allows money tobe instantly sent and received by different banks, companies, and countries through computers andtelecommunications devices.
