Chapter Electronic Payment systems 10.1 Traditional Electronic Payment Systems for Electronic Commerce In electronic commerce, the challenges of payment transactions were initially underestimated Business via the internet and mobile telephony has so far been dominated by the methods of payment customary in traditional business. However, in light of technological progress

Describing the fundamental physical properties of materials used in electronics, the thorough coverage of this book will facilitate an understanding of the technological processes used in the fabrication of electronic and photonic devices. The book opens with an introduction to the basic applied physics of simple electronic states and energy levels. Silicon and copper, the building blocks for many electronic devices, are used as examples. Next, more advanced theories are developed to better account for the electronic and optical behavior of ordered materials, such as diamond, and disordered materials, such as amorphous silicon. Finally, the principal quasi-particles (phonons, polarons, excitons, plasmons, and polaritons) that are fundamental to explaining phenomena such as component aging (phonons) and optical performance in terms of yield (excitons) or communication speed (polarons) are discussed

Electrons are the “glue” that holds the nuclei together in the chemical bonds of molecules and ions. Of course, it is the nuclei’s positive charges that bind the electrons to the nuclei. The competitions among Coulomb repulsions and attractions as well as the existence of non-zero electronic and nuclear kinetic energies make the treatment of the full electronic-nuclear Schrödinger equation an extremely difficult problem. Electronic

Chapter 1 Introduction of Electronic commerce 1. 1 Development of Electronic Commerce(e-commerce 1.1.1 Histor Throughout history, attempts to promote new means of communication were simply means with which to increase opportunities for ease, efficiency and security. The foundations on which electronic commerce is based started 125 years ago with the use of telegraph

Chapter 5 Electronic commerce information's search and selection In physical markets, consumer search activities include reading advertisements, calling endors, and visiting stores. In a virtual marketplace, all these activities seem to converge into Web searches and Web browsing. Not surprisingly, search services are the first market infrastructure to be built in the electronic marketplace
