The advancement of technology recently urges city branding practitioners to implement smart tourism. In short, smart tourism refers to the usage of the latest information technology to support the tourism sector's development. Enhancing the capability of utilizing the "Internet of Things" is deemed pivotal in tourism development. It makes things easier for tourists, but it can also widen potential markets for the tourism sector. This study aims to explore the extent of smart tourism development in Indonesia. It is done through content analysis of available literature, mainly focused upon a single city case study. By summarizing these kinds of literature using a comparative technique, this study finds that most Indonesian cities still use mobile applications. Other than this, there are many indicators in smart tourism yet to be achieved, such as smart vehicle scheduling, crowd handling, Intelligent-Guide System, travel safety protection. This study uses three dimensions in evaluating smart tourism: technology, people, and institutional dimensions. This study found some challenges, such as human resources' capabilities in using technology and funding limitations. Suggestions to overcome these challenges and improve smart tourism implementation are proposed, such as collaboration between the private sector and the government to enhance technology's service quality and target specific potential customers using social media.
