This research paper reports the results of a study of M-commerce services adoption in Germany. A quota sample of two hundred respondents was taken in Berlin using a face-to-face questionnaire. Data regarding the use or intention to use M-commerce services, factors that influenced or might influence their adoption of the services, as well as demographic characteristics were collected. The data is analyzed using the Technology Acceptance Model (TAM) and Structural Equation Modelling (SEM). Further theoretical development is conducted using the broad approach taken by Venkatesh et al. (2003) in the development of the Unified Theory of Acceptance and Use of Technology (UTAUT): a focus on constructs that can readily be measured. The result is the Simplified Theory of Technology Acceptance (STAT). This model is unique in that it is parsimonious and yet achieves a high degree of predictive power. The model also includes a new construct called Readiness to Use. This construct was suggested by the SEM analysis and is found to be a useful addition to conceptualization and modelling of the adoption of new information technologies in a consumer context.
