Mobile phones can be used for financial services in three different ways: for micro payments (m-commerce), as electronic money (e-money), and as a banking channel. The report examines who offers mobile phone banking services to poor customers? Why is there so much excitement about banking the poor with mobile phones? What are some reasons to be cautious? This reports that the Consultative Group to Assist the Poorest (CGAP), in partnership with the Vodafone Group Foundation and the United Nations (UN) Foundation, is now doing research in the Philippines and South Africa to find out what makes poor people use or reject these services and how remote mobile phone banking can go. This research can help banks, microfinance institutions, mobile phone companies, regulators, and donors steer mobile banking toward reaching large numbers of the poor.

A survey integrating different theoretical views of value creation was developed, then sent to Portuguese e-ommerce firms to assess the underlying dimensions and the most important characteristics of their e-Commerce strategies. The survey was sent to 188 firms in 2007 and repeated in 2010 to validate the results, obtaining a total sample of 62 e-Commerce firms. Through factorial analysis, three e-Commerce strategy dimensions were identified: one relates to differentiation via marketing based on reputation and brand identification, in which advertising and innovation in marketing techniques and methods are important; a second differentiation dimension focuses on product development and is supported by technical capabilities; and a cost leadership dimension which uses strategic networks to obtain economies of scale and scope, and exploits technological advancements to reduce transaction costs.
The current climate of business necessitates competitions that are often tough and unpredictable. All organizations, regardless their size and scope of operation, are facing severe competitive challenges. In order to cope with this phenomenon, managers are turning to e-commerce in their respective organizations. The present study hinges upon exploring and explaining the different dimensions of the adoption of e-commerce among Small and medium enterprises, based on the Five Factors of Diffusion of Innovation Model derived by Rogers. In this study, however, we employed the survey methods. A questionnaire was distributed to 1,200 managers and employees in the manufacturing, service and agricultural sectors by email; with a response rate of 10%. The results gleamed from this study posits that relative advantage is influential vis-à-vis e-commerce adoption. Trialability and Observability factors affect the level of confidence of management, which in turn, influences e-commerce adoption. Meanwhile, the existing culture of a company affects the resistance of employees, which in turn negatively effects the e-commerce adoption, while complexity does not significantly influence the e-commerce adoption.

Non-repudiation in e-commerce has recently gained a lot of interest but its successor brother, non-repudiation in m-commerce, is still at the start. In this paper, we propose an extension of existing mobile payment models to introduce an extended mobile payment service (EMPS) model, which is based on assumptions about the cooperation between mobile network operators and financial institutions to deal with different payment amounts ranging from micro to macro payment. The novel model focuses on enhancement of non-repudiation problem. Fair non-repudiation protocols are developed for not only payment phase but also other phases in a typical m-commerce transaction, including price negotiation and content delivery. Joint signatures method is used in protocols to overcome the limitations in mobile handheld device capability and to reduce the trust dependence totally on the payment service. As with the proposed non-repudiation protocols, EMPS plays the role of a semi-trusted third party and is an indispensable factor for creating the fairness property. Non-repudiation analyses of these protocols are also conducted besides some guidelines for ensuring non-repudiation in m-commerce.
