Unique Features of Mobile Commerce

While the market potentials and impacts of web-based e-commerce are still in the ascendant, the advances in wireless technologies and mobile networks have brought about a new business opportunity and research attention, what is termed mobile commerce. Commonly, mobile commerce is considered to be another new application of existing web-based e-commerce onto wireless networks, but as an independent business area, mobile commerce has its own advantages and challenges as opposed to traditional e-commerce applications. This paper focuses on exploring the unique features of mobile commerce as compared with traditional e-commerce. Also, there are still some limitations arisen in m-commerce in contrast to web-based e-commerce. Finally, current state of mobile commerce in Japan is presented in brief, with an introduction of several cases involving mobile commerce applications in today's marketplace.

The Development of an Instrument to Measure Mobile Game Quality

Electronic games are often considered one of the main consumer markets in the mobile commerce arena. This is an area that has thus far been neglected by literature. The research performed in this paper develops and validates the usefulness of an instrument that evaluates the quality of mobile games. Data collected by the instrument is grounded in subjective impressions, which can be applied in quantitative analysis for the production of mobile game metrics including the Mobile Game Quality Index. These objectives are carried out through a three-step methodology. First, an instrument to measure the construct of interest, mobile game quality is developed. Then the instrument’s validity is examined and demonstrated in two phases of testing on mobile games. A five dimension structure of mobile game quality is revealed along with a validated 23-item instrument. The resulting quality model is found to have strong theoretical support in the literature.

Supporting Mobile Commerce Applications Using Dependable Wireless Networks

Mobile commerce (m-commerce) is an emerging discipline involving applications, mobile devices, middleware, and wireless networks. While most of existing e-commerce applications can be modified to run in a wireless environment, m-commerce also involves many more new applications that become possible only due to the wireless infrastructure. These applications include mobile financial services, user and location specific mobile advertising, mobile inventory management, wireless business re-engineering, and mobile interactive games. In addition to device and wireless constraints, mobile commerce would also be impacted by the dependability of wireless infrastructure. Unlike e-commerce applications that usually run on fixed networking infrastructure of fairly high dependability (approaching to about 100%), m-commerce applications may not receive such high dependability from the existing and emerging wireless infrastructure. So far, most of the m-commerce research focuses on applications, devices, and security issues. We believe that some work is necessary in addressing the dependability challenges of the wireless infrastructure. In this paper, we present (a) the dependability issues of wireless infrastructure, (b) several architectures to improve the dependability of wireless networks, and (c) a simulation model and results on wireless dependability for m-commerce. The results show that a significant improvement is possible in wireless dependability for supporting m-commerce applications.

Understanding dynamics between initial trust and usage intentions of mobile banking

Mobile banking is an emerging application of mobile commerce that could become an additional revenue source to both banks and telecom service providers. It is a form of service convergence enabled by innovative technologies. Despite the alleged benefits of mobile banking, its acceptance has been short of industry expectations. One plausible explanation may be consumers' initial lack of trust in available services. The objective of our research is to reveal the mechanisms associated with the initial formation of people's trust in mobile banking and intention to use the service. For this, we attempt to understand the effect of four antecedent variables (structural assurances, relative benefits, personal propensity to trust and firm reputation) on shaping a person's initial trust in mobile banking and its usage intention. They represent four types of trust-inducing forces: institutional offering (structural assurances), cognition (perceived benefits), personality (personal propensity) and firm characteristics (firm reputation). We examine individual significance of the selected antecedents and also their comparative reliability in explaining the two exogenous variables. The technical basis of our empirical research is the innovative mobile banking solution that uses cellphones with a built-in smart chipset. The survey data are analyzed using structural equation modelling. The analysis showed that three variables (relative benefits, propensity to trust and structural assurances) had a significant effect on initial trust in mobile banking. Also, the perception of initial trust and relative benefits was vital in promoting personal intention to make use of related services. However, contrary to our expectation, the reputation as a firm characteristics variable failed to attract people to mobile banking.
