The Impact of Wireless Application Protocol (WAP) on M-Commerce Security

Abstract

Mobile commerce (m-commerce) is providing commercial services that are accessible using mobile devices, typically a mobile phone. The main advantage of such services is their high availability, independent of physical location and time. Yet the move to create a wireless version of the Internet means a new set of problems. As with the existing fixed Internet, the biggest problem is security. Despite the fact that operators are announcing or rolling out Wireless Applications Protocol (WAP)-based information and transaction services, the platform has gaping security holes. Because security is the most important feature to the success of m-commerce, this paper studies the security concerns on wireless commercial Internet and presents the features and solutions of WAP to the security of electronic transactions. Most importantly, this paper intends to draw corporate executives' attention to the strong impact of WAP on m-commerce security and the associated benefits to their companies.

Can Mobile Money Help Firms Mitigate the Problem of Access to Finance in Eastern sub-Saharan Africa?

ABSTRACT

Mobile money is a mobile-phone-based financial tool that can transfer money safely and quickly across a wide geographical area. Mobile money has transformed the way businesses in Eastern sub-Saharan Africa operate. Nowadays, banks team up with mobile-money-service providers and pay interest on deposits and grant loans based on financial transactions in mobile-money accounts. In this paper, these recent developments are investigated in order to determine whether the adoption of mobile money by firms can actually help them mitigate the vexing problem of access to finance. To answer this question, the World Bank’s Enterprise Surveys Program data set for the year 2013 is used, thus making the study applicable to the present time. The results obtained, after controlling for a large number of firm-level characteristics and using a newly introduced measure to identify access-to-finance status of the firms, indicate that firms which use mobile money are more likely to obtain loans or lines of credit. Further analysis shows that the firms that use mobile money are more productive than other firms in the region.     

The effect of presentation,product availability and ease upon transaction reliability for online food delivery aggregator applications – moderated mediated model

ABSTRACT

With advancements in mobile technologies, online food-delivery aggregators (OFA) have become an important distribution channel for restaurants. This study examines how the OFA applications affect diner’s cognitive and affective states and subsequent behavior by empirically testing a research model that incorporates antecedents of transaction reliability for restaurant order booking using a mobile application. Data collected from a survey of 458 respondents are analyzed using SEM. Drawing from SOR, CVT, and cue theory, the research established that product presentation and ease of use predict transaction reliability and are important mobile application attributes while choosing a particular OFA. The moderated mediation model extends the stimulus-organism-response framework and the consumer value theory. The findings demonstrate the moderating influence of gender, where the relationship is stronger for females. The study has a positivist approach with causalities satisfying the fundamental law of SOR theory. Higher media richness shall lead to a positive feeling about the product. A good presentation of the products on the mobile screen shall enhance the perception of product availability. The presence of abundant products makes it easy to search, thereby ease of searching the mobile screen. Mobile applications should be updated regularly to keep pace with the ever-changing mobile technologies.

Mobile technologies for police tasks: An Australian study

Mobile technologies are increasingly adopted by information intensive organizations such as public police corporations to support the tasks of its employees, for information management and innovation. However, because police organizations are government organizations, technology decisions are largely made by managers and politicians with budget being a key factor. Therefore, whether the technologies adopted are suitable for police tasks, and if they enhance performance, is generally not assessed. The aim of this research is to establish if mobile technologies support police tasks, and if Tablet PCs especially are suitable for specialist police tasks of the Criminal Investigators and Sexual Offence and Child Abuse Units. Guided by an interpretive paradigm and the theory of task technology fit, this research explores the use of Tablet PCs by the two police units for improved performance. Because information is critical for police tasks, data collected via focus groups establishes the impact of these technologies on case investigations, information management, and the performance of these units with the use of Tablet PCs. The contribution this study makes to mobile information systems is that if technology dimensions are suitable for information based tasks, the outcome is virtualization of processes through which improved performance is achieved due to reduced costs, transparency, teamwork, and quick and informed decisions. The findings of this research can be used by police organizations, as well as by other organizations, for effective implementation of mobile technologies.
