A rapidly developing application of extranet and Internet technology is providing for online commercial transactions known as Electronic Commerce. An organization becomes virtual when it presents itself largely electronically (rather than, for example, a physically existing building) as a web page to be accessed through Internet access. Commerce takes place via online catalogues, email, and credit cards and electronic payment systems. Only physical delivery of purchased goods takes place outside the electronic system. Online Publishing, Internet Banking, Business-to-Business transactions also introduce a virtual aspect to organizations. Issues of trading legislation, security and ethics are important issues for providers and consumers. There are also important social implications as these technologies bring about lifestyle changes, render many employee positions redundant, and lead to bank branch, and traditional commercial outlet closures.
