Wireless Internet via mobile devices (WIMD) is leading the world into another spectrum of communications and means of conducting day-to-day business and life activities. Full bloom of wireless Internet services depends on user acceptance, as well as technology improvement. This paper develops a technology acceptance model for wireless Internet via mobile devices (TAM for wireless Internet), a conceptual framework to explain the factors influencing user acceptance of WIMD. By revising the technology acceptance model (TAM) to represent some unique features of the wireless system under study, TAM for wireless Internet proposes that constructs such as individual differences, technology complexity, facilitating conditions, social influences, and wireless trust environment determine user-perceived short and long-term usefulness, and ease of using WIMD. These, in turn, determine user intention and willingness to adopt WIMD. Twelve propositions are developed to promote and facilitate future empirical research relating to WIMD.

Despite the recent economic downturn in the Internet and telecommunication sectors, electronic commerce (EC) will continue to grow and corporate Web sites will remain an important communication channel. However, legitimate concerns regarding privacy and trust remain potential obstacles to growth and important issues to both individuals and organizations. This study proposed and tested a theoretical model that considers an individual's perceptions of privacy and how it relates to his or her behavioral intention to make an online transaction. An experiment that included over 200 subjects was conducted using two EC sites that differed only by the privacy dimensions of their notice, access, choice, and security. The results of this study suggested strong support for the model. #
