Mobile devices are increasingly getting popular, especially with the younger generation who wants fast and convenient services. These services include messaging, gaming, making financial transactions, shopping, and downloading music and movies. But while mobile devices have great potential in e-commerce, limitations, such as screen size, small keyboards, little memory, and lower processing powers, hindered the use of such devices for serious e-commerce transactions. From the usability study carried out in Singapore, we found that more than half of the e-commerce users (54%) are aware of the WAP and wireless technology and are also familiar with mobile devices. The study also shows that most users utilize the Internet for accessing e-mail, online news, and sometimes online shopping. Not all e-commerce users use WAP for e-commerce transactions despite the fact that most of their mobile devices are WAP enabled. The study showed that most users prefer to use desktop for Internet access, citing that size of the screen, speed, stability, and security are some of the reasons. E-commerce users in Singapore view security to be an issue in both fixed-network and wireless technology. They have not completely adopted and embraced the wireless technology, as the immediate benefits may not be that apparent yet. There is still a lot of development work to be done to improve the limitations of mobile devices and network bandwidth.
Despite all of these limitations, wireless technology and mobile devices are still attractive and have great potential in m-commerce. Fast and easy access to information is becoming important for people on the move. Convenience of access is also one of the many attributes of mobile devices that consumers are looking for.
