求翻译英文文章 In ancient times wealth was measured and exchanged in things that could be touched:
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 had real value since they were pieces of rare metal. Coins were followed by fiat money, paper notes that have value only because everyone agrees to accept them.
Today electronic monetary systems are gradually being introduced that will transform money into even less tangible forms, reducing it to a series of “bits and bytes”, or units of computerized information, going between machines at the speed of light. Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries through computers and telecommunications devices.

现如今,电子交易系统逐渐被推广并把钱变形为有形资产,减少了一系列位与字节或计算机单元信息化的问题,以光速在机器间发展.电子科技的基础早已让钱能够通过电脑和通讯瞬间在不同的银行、公司、国家发送并接收
