The rapid growth of Malaysia�s e-commerce industry has caused the logistics industry to serve a rapidly increasing number of customers, mainly in the last-mile delivery sector. Thus, there is a need to use advanced technology, such as IoT to handle this challenge. MIMOS has carried out an IoT roadmap, but the development is still slow. Therefore, the purpose of this paper is to investigate the perceptions and attitudes of courier companies towards the adoption of IoT. For this research study, in-depth interviews with four courier companies in Malaysia were used to gather their perceptions and attitudes towards adopting IoT using the Technology Readiness (TR) construct as a guideline. Content analysis was then utilized to determine participants� attitudes. This paper proposes a model to help decision-makers predict the IoT's intended use. The results show the majority appear to have a positive outlook on IoT. The respondents reacted more to positive views, optimism, innovativeness, and convenience than negative views, which are risk-taking propensity. The findings of this study provide some guidelines for courier companies to evaluate IoT adoption in their firms. Moreover, the government can also benefit from this study by encouraging the acceleration of the IoT roadmap. The technology readiness in this study has been accessed qualitatively differently from earlier studies on technology readiness that used survey methods and scale. For future research, it is encouraged to acquire research data from different sectors in courier services, which are local and international. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
