Abstract

Due to the fast development of mobile technologies and wireless communications, more people are using mobile devices. Mobile devices like cellular phones are initially used for data communications, as in speech. Now, mobile devices are not only portable but also can be used to communicate and exchange information as well as gain access to remote services anywhere, anytime. But while mobile devices offer many opportunities for e-commerce applications, conducting e-commerce transactions over mobile devices has its limitations. Limitations include limited memory, limited processing power, different technologies and standards, small keyboards, and small screens. A usability study was carried out to determine the extent to which mobile devices can be used in mobile commerce. Most of the studies showed that while mobile devices are becoming increasingly popular with the younger generation, users still prefer to use desktops for e-commerce transactions. This is mainly due to the limitations of mobile devices and the stability and security of the wireless networks.
