This text is unique in bringing together the many disparate aspects of what is variously called internet law, cyber law or electronic commerce ('e-commerce') law. Included is the law relating to online contracts and payment systems, electronic marketing and various forms of cybercrime as well as the regulation of electronic communications networks and services. Insights are also given into emerging areas such as internet libel, online gambling, virtual property, cloud computing, smart cards and electronic cash, as well as the growing use of mobile phones to perform tasks previously carried out by computers. The rapid, commercially driven evolution of the Internet has raised concomitant legal concerns which have required responses from both national and international law. However, the pace of development within the telecommunications sector has been such that, no sooner has the law begun to regulate the area of e-commerce, than it is being expected to address new issues associated with 'mobile commerce' ('m-commerce'). The four authors and their contributors have drawn on specialist knowledge to provide a complete analysis of e- and m-commerce law which will be invaluable to business, industry and the legal profession. The combination of international authors ensures that every aspect of this global subject is dealt with from a cross-jurisdictional perspective. In charting the full spectrum of technology-driven, commercially oriented and frequently consumer-related legal issues, they provide timely critical insight into this crucial and constantly evolving legal arena.
