One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations , whether or not the local branch bank is open. For many of us the "cashless society" is not on the horizon—it's already here. While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customers for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer-analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future, and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself. Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.

【T1】Over the last few years the Internet has evolved from being a scientific network only, to a platform that is enabling a new generation of businesses.The first wave of electronic bussiness was fundamentally the exchange of information. But, with time, more and more types of businesses have become available electronically.【T2】Nowadays we can buy goods online, book holidays or have texts translated over the Internet in an instant.Home banking, for example, is one application that is already provided by most banks around the world. Looking up your balance, transferring money and other transactions are done every day by millions of people. Public administration has discovered the Internet as means to talk to the general public at election times. And it will not be a long time before we see general elections decided on the Internet. The reason why I have called this book "The E-business Revolution" is that the approach is twofold. Technology has revolutionized the way we can do business. But business itself is only slowly adapting to the new possibilities. The New Economy needs a new paradigm, but the process of conversion will take some time to complete. The necessary technology is ready and waiting.【T3】The e-business in the title is not the same as IBM is seeing, it is much more, as you will discover by reading this book, therefore the "B" in e-business is not written in capital letters as in IBM's case.The Internet is changing the concept of programming applications. We are moving towards pervasive computing and towards electronic services. The Jini technology is one of the first implementations of what one could call "one world, one computer". Jini allows every device to talk to every other device in a common language.【T4】A device in this case can be anything with a silicon chip inside and an Internet connection.Other companies have started to develop similar paradigms, technologies and visions, such as IBM's T-Spaces technology and Hewlett-Packard's E-Services strategy. 【T5】Most probably you already know the example of the empty refrigerator that sends an e-mail to the grocery with a request for fresh milk that will be delivered to the doorstep before breakfast in the morning.Prototypes have already been built. A bar-code reader is able to detect which products are put into the fridge and taken out afterwards. For many people this won't been necessity in the future. The grocery is more than just a piece where people can buy food. It is a social place where people meet, which cannot be simply replaced by two chips. But for those who do not have the time to do shopping or are not able to walk to the grocery, this may become an option.
