The study sought to find out the effect of Technological Readiness Index (TRI) on the adoption of the inDubai application by potential tourists to Dubai. The finding showed a distinct relationship between TRI dimensions and the intention to make use of the inDubai mobile application. The findings of the study further proved that the TRI model as developed by Parasuraman can indeed prove the intention of individuals to adopt a new technology. The study showed that if the first two dimensions (Optimism and Innovation) are present, then a traveler will most likely see the perceived benefits of using the product or technology which in turn will lead to a positive intention to adopt such a technology. The findings also showed that if the last two dimensions (Insecurity and Discomfort) are present then such individuals exhibiting these behaviors are less likely to want to adopt this new technology. This implies that applications like the inDubai application and other similar applications need to address issues that lead to insecurity and discomfort among users if they are to attract a lot of adopters.
