Abstract There are a number of theories and models that
have been employed over the years in understanding and
studying users’ technology adoption behaviors. These
theories and models focus on people’s intention to engage in
a certain behavior such as the adoption and use of new
technologies. The Theory of Reasoned Action (TRA) is one
of such theories that have been widely used in technology
adoption as well as used in a number of other research fields
as a foundation to such studies. Most of the Information
Systems scholars, who have used this theory, have used only
to set a foundation or help build other theories and models.
TRA has therefore been compared with other theories and
models for technological innovation, and found to be a
strong theory for innovation adoption upon a few additions
of other variables such as facilitating conditions, awareness
of innovation by users, social pressure and user readiness.

1. Introduction
Theory of Reasoned Action (TRA) was formulated by
Ajzen and Fishbein [1]. This resulted from attitude research
using the Expectancy Value Models [2]. The formulation
came forth after trying to estimate the discrepancy that
existed between attitude and behavior. The fundamentals of
the TRA come from the field of social psychology. Social
psychologists attempt, among other things, to explain how
and why attitude affects behavior, which is equally very
important in mirroring this study. That is, how and why
people’s beliefs change the way they act. Behavior can
either be verbal or non-verbal such as body language,
signals, signs, or vocally expressed. Psychologists argued
about what should make up the term attitude. Social
psychologists suggest that attitude includes behavior and
cognition, and that attitude and behaviors are positively
correlated. This is the reason why Theory of Reasoned
Action is well placed in conducting studies on technological
innovation.
2. Literature Review
TRA was formulated by Ajzen and Fishbein [1]. It
resulted from attitude research using the Expectancy Value
Models [2]. The formulation of TRA was after trying to
estimate the discrepancy that existed between attitude and
behavior. The fundamentals of the TRA come from the field
of social psychology. Social psychologists attempt, among
other things, to explain how and why attitude affects
behavior, which is equally very important in mirroring this
study. That is, how and why people’s beliefs change the
way they act. The study will look at how attitude and beliefs
affect the utilization of mobile phone money. Behavior can
either be verbal or non-verbal such as body language,
signals, signs, or vocally expressed. TRA put forth three
general constructs namely: (1) behavioral intention, (2)
attitude, and (3) subjective norm.
TRA has been tested in numerous studies across many
disciplines and cases including dieting, using condoms,
consuming genetically engineered foods and limiting sun
exposure [3]. The theory can be extended to conceptualize
the human behavioral pattern in the decision-making
strategy on the utilization of a new innovation or
technology. It is capable of explaining whether individual
behavior such as utilization of new innovation is driven by
behavioral intentions, where behavioral intentions is a
function of an individual’s attitude toward the behavior, the
subjective norms surrounding the performance of the
behavior, and the individual’s perceptions of the ease with
which the behavior can be performed. The theory has not
extensively been utilized in evaluating studies such as
technology adoption and diffusion. In the Information
Systems literature, this theory has only been used in
identifying users’ behaviors and attitudes in issues relating
to Internet use, online purchase, household computer use,
and online privacy, security, and trust [4]. Social
