Abstract: Mobile-Commerce, also called M-Commerce, is a new trend and is expected to be the next big wave of our society. A number of M-Commerce devices, services and applications have been developed and are already in use, covering a wide range of individual functions, from voice message transmission to access to the Internet. In this regard, it is very important to understand factors that affect individuals` use and the adoption of M-Commerce as users of M-Commerce are projected to be increased in the future. Therefore, in this paper, the Technology Acceptance Model (TAM) proposed by Davis (1989) and Davis, Bagozzi and Warshaw (1989) has been applied to investigate the effects of new variables on individuals` behavioral intention to use and adopt M-Commerce. Besides two beliefs in the original TAM-perceived ease of use and perceived usefulness, other relevant variables, such as (1) Socio-Economic Status (SES), (2) Perceived Mobility (PM), (3) Job Relevance and (4) Social Influence (SI) are included in the proposed M-Commerce adoption model.
