Abstract	The Internet of Things (IoT) has revolutionized attendance management by enabling automated, real-time tracking through devices like RFID tags, biometric scanners, and mobile applications. However, IoT-based attendance systems that do not leverage blockchain technology face critical challenges, including security vulnerabilities, data privacy risks, scalability constraints, interoperability limitations, and reliability issues. This paper provides an exhaustive analysis of these problems, supported by real-time data from industry reports and case studies (up to July 2025), visualized through tables and charts. We explore issues such as unauthorized access, data tampering, single points of failure, protocol incompatibilities, and system downtimes, detailing their technical, operational, and economic impacts. Mitigation strategies, including advanced encryption, hybrid architectures, standardization efforts, and privacy-enhancing technologies, are thoroughly evaluated, highlighting their limitations in non-blockchain frameworks. This study aims to inform researchers, practitioners, and policymakers about the challenges and guide the development of robust IoT-based attendance systems.
