This chapter provides an overview of the existing e-commerce infrastructure in Developing Countries. A comprehensive survey of all the technologies used in e-commerce is introduced at the beginning of the chapter followed by a description of e-commerce infrastructure components. This chapter groups e-commerce infrastructure into three difference categories, namely: technological infrastructure, financial infrastructure, and the legislative infrastructure. An overview of the current technological, financial, as well as legislative e-commerce infrastructure in Developing Countries is provided which shows that many developing countries do not have the infrastructure required to provide e-commerce services. The author acknowledges the importance of e-commerce and its impact on the economy of any country and hopes that a clear understanding of the entire underlying infrastructure can help the Developing Countries to accelerate the growth of its e-commerce services.
