212 Mobile Electronic Commerce
12.1 Introduction
Mobile device technology is in its growth phase, and there are a wide
variety of mobile devices, with new products being introduced at a rapid
pace. Competing vendors rush to introduce new and innovative fea-
tures, withmuch emphasis placed on user interaction richness. This con-
trastswith developments in mainframe and desktop systems, where most
of the development was focused on benetting from increasing processing
power and storage, with one major shift from the text-based, command
line, interface to the window, icon, mouse, pointer (WIMPy)–based graphic
user interface in the 1980s. The other major paradigm shift in business
computing was the move from in-house computing, with trained employ-
ees accessing systems, to customers directly accessing business systems, as
is the case in e-commerce. Systems developers, building systems for direct
customer access, had to build adequate safeguards to prevent data corrup-
tion and design the interface to meet customer expectations. A dominant
platform arose quickly for business developers with the MS Windows
environment dominating in the case of desktop computing and a combi-
nation of hypertext markup language (HTML) and JavaScript becoming
the dominant web e-commerce environment. This simplied development
and developers could focus on one dominant technology. However, in the
case of mobile computing, there are multiple vendors promoting their own
platforms; in some cases, a single hardware vendor may support multiple
operating systems. Mobile computing places a premium on high intercon-
nectivity, rich multimodal interaction, and user mobility. These features
are rare in conventional systems development, and developers need to
understand the benets and limitations of the technologies used in mobile
computing. In addition, mobile network providers favor some modes of
connectivity over others, making it necessary for developers to alter appli-
cations based on communications network providers. The highly fractured
marketplace makes it challenging to develop mobile electronic commerce
applications that can function effectively on different devices.
Developers may either choose to build and optimize for one plat-
form or build a multiplatform application that provides satisfactory
performance on multiple platforms. This impacts the choice of a suitable
