E-commerce is the use of electronic communications and digital information processing technology in business transactions to create, transform, and redefine relationships for value creation between or among organizations, and between organizations and individuals. In e-commerce, information and communications technology (ICT) is used in inter-business or interorganizational transactions and in business-toconsumer transactions In e-business, on the other hand, ICT is used to enhance one’s business. It includes any process that a business organization (either a for-profit, governmental or non-profit entity) conducts over a computer-mediated network. A more comprehensive definition of e-business is: “The transformation of an organization’s processes to deliver additional customer value through the application of technologies, philosophies and computing paradigm of the new economy. Three primary processes are enhanced in e-business: 1. Production processes 2. Customer-focused processes. 3. Internal management processes M-commerce (mobile commerce) is the buying and selling of goods and services through wireless technology-i.e., handheld devices such as cellular telephones and personal digital assistants (PDAs) The Internet allows people from all over the world to get connected inexpensively and reliably. the Internet is an enabler for e-commerce as it allows businesses to showcase and sell their products and services online and gives potential customers, prospects, and business partners access to information about these businesses and their products and services that would lead to purchase. E-commerce transforms old economy relationships (vertical/linear relationships) to new economy relationships characterized by end-to-end relationship management solutions (integrated or extended relationships). An electronic payment system (EPS) is a system of financial exchange between buyers and sellers in the online environment that is facilitated by a digital financial instrument (such as encrypted credit card numbers, electronic checks, or digital cash) backed by a bank, an intermediary, or by legal tender. The government plays an instrumental role in encouraging e-commerce growth through concrete practicable measures such as: 1. Creating a favorable policy environment for e-commerce. 2. Becoming a leading-edge user of e-commerce and its applications in its operations, and a provider to citizens of e-government services, to encourage its mass use. Government can use e-commerce in the following ways: ● E-procurement. Using open standards-through ‘agency enablement’ programs, ‘supplier enablement’ programs. ● Customs clearance. With the computerization of customs processes and operations one can expect more predictable and more precise information on clearing time and delivery shipments. ● Tax administration. This includes a system for electronic processing and transmission of tax return information, permits, and licenses, and an electronic process registration of businesses.
