  This study investigates smartphone users perceptions of adopting and
accepting Mobile Commerce (MC) based on users perceived adoption under the
extended Technology Acceptance Model (TAM2) and Innovation Diffusion Theory
(IDT) by providing research constructs for the domain of MC. Also, testing them
with reliability and validity and demonstrating their distinctiveness with
hypothesis testing. The results show that consumer intention to adopt MC on a
smartphone was primarily influenced by Uncertainty Avoidance (UA), User
Experience (UX), Perceived Ease Of Use (PEOU), Perceived Usefulness (PU) and
Compatibility (CMP) as well as other constructs that positively determine
attitude toward using a smartphone. For researchers, this study shows the
benefits of adapting TAM constructs into MC acceptance on a smartphone. The
perceptions of MC adoption on a smartphone in this study investigated based on
a survey of specific people. For more reliability, a comprehensive study is
needed to show the attitudes of people from different environments.
