This study aims to explore and model the central consumer perceptions that affect the decision of
whether to use mobile payment systems. In particular, we study whether the Technology Acceptance
Model (TAM) describing user acceptance of technology offers comprehensive explanation for
consumer decisions related to adoption of mobile payments.

This study is based on two rounds of focus group interviews, the total number of subjects interviewed
being 61. Our analysis suggests that the Technology Acceptance Model (TAM) provides a good basis
to explain use of mobile payment solutions, yet, our data proposes that a new construct, trust, should
be included into the model to augment the present descriptors in explaining consumer adoption
decisions in the mobile payment context.
