Cash is no longer king. In many countries digital payment is taking over in all money transactions, a development that is proceeding rapidly. A Cash Free Society describes this process and highlights the advantages and disadvantages of a cashless society.

Information Technology (IT) is conquering the world. It affects our jobs, our lives as private citizens, and society. Its impact is greater than other technologies, such as railways, personal cars, and the telephone. However, while most can understand the potential and constraints of these technologies, IT is often experienced as a ';black box,' producing its effects without giving a clue as to how they are achieved. The aim of How Information Technology Is Conquering the World is to open this box and to offer a basic knowledge of the technology and how it works. We will then understand why IT can put toll both operators, metro train engineers, and stockbrokers out of a job, but at the same time have limited impact on bus drivers, nurses, and teachers.How Information Technology Is Conquering the World focuses on the interface between the technologies and the real world in order to explore not only where these technologies have their advantages but also where their limitations become apparent. The difficulty of introducing a new technology is emphasized with the practical goal of enabling readers to use technology to full advantage. This book is useful for those involved in, affected by, or interested in the technology; for students taking an introductory course in computing; and for managers and others who are interested in seeing how this rapidly evolving technology will affect their lives, jobs, and businesses now and in the future.

A few years ago, many new Internet businesses failed as a result of an unrealistic view of the potential of the Internet, the Web, and computer technology in general. Today Internet and Web technologies are gaining a strong foothold by offering new and different ways of doing business in many areas. This book offers a clear and concise overview of the fundamental principles of computing by building a framework for understanding computer applications. In Parts 1 and 2 author Kai Olsen defines formalized and unformalized processes, with a focus on the formalization of Internet and Web technologies. Parts 3 and 4 explore these concepts further in a discussion of eBusiness applications within B2C (Business-to-Consumer) and B2B (Business-to-Business) models. Presenting numerous examples, tables, and graphics throughout, the ideas introduced in the first half of the book are expanded upon in an easy-to-understand manner. Part 5 prophesizes about the effects that these technologies will have on everyday life, jobs, and society in the future. This book is essential for those involved in, affected by, or interested in Internet and Web applications relating to eBusiness. It will be useful as an introductory textbook in courses about human-computer interaction, eBusiness, mass communications, and of general interest to library and information studies students.
