The author first developed the database based on the data from Jabatan Kemajuan Islam Malaysia JAKIM, which is Malaysian Halal logo identification authority then the mobile application which uses the Near Field Communication to detect the Halal food using the Radio Frequency Identification. In this study, the authors have developed the mobile application which is based on Radio frequency identification near field communication RFID/NFC. Malaysia is a modern Muslim country where the research on Halal product identification is at the peak. The study's findings provides deeper insight into the current state of IoT research in the halal food literature, its development, challenges and future research avenues for scholars, policy makers and the HFSC community. Several challenges were identified, such as the technical limitations of IoT devices, technological immaturity, lack of user acceptance, cost and regulatory barriers. The results reveal that IoT offers five major benefits for the HFSC namely, traceability of products, enhancement of supply chain efficiencies, facilitation of livestock management, authentication of foods’ halal status, and monitoring of halal certifications. To begin, over seventy-three (73) papers were analyzed using both bibliometric techniques and in-depth content analysis. Therefore, the goal of this paper is to address the knowledge gap concerning IoT in the HFSC and review IoT research within the context of HFSCs. Despite its growing popularity in supply chain management and logistics, the potentials and challenges of IoT in the HFSC remains - unexplored and requires further research.

The emergence and proliferation of the Internet of Things (IoT) - the use of interconnected devices, sensors, and technologies to orchestrate, monitor, and optimize supply chain processes- holds innovative potentials for the halal food supply chain (HFSC). To address consumers’ concerns regarding the integrity of food, halal food businesses need to rethink their conventional supply chains and leverage new technologies.
