Smart cards have been widely used in the fields of transportation, telecommunications, and retail for monetary storage and identity verification. In educational field, smart student ID cards are also utilized in the construction of smart campuses. This study focuses on student injury and illness management, exploring the effectiveness of the smart student ID card (referred to as the "Chia-E-Card") promoted by the Chiayi City Government in Taiwan for managing student injuries and illnesses. It delves into its actual impacts on students, teachers, school nurses, and parents. Through questionnaire surveys and comprehensive quantitative data analysis, the results indicate that the Chia-E-Card significantly enhances the efficiency and quality of injury and illness management. Users generally provide positive evaluations of their experience and satisfaction with the card. The application of the Chia-E-Card not only accelerates the response time for student injuries and illnesses but also increases information transparency, enabling teachers and parents to obtain timely information regarding student health issues. This study finds that factors such as system quality, information quality, service quality, perceived ease of use, and perceived usefulness are significantly positively correlated with user satisfaction and behavioral intentions. Based on the findings, several improvement suggestions are proposed, including enhancing system quality, improving information quality, optimizing service quality, enhancing perceived ease of use, and strengthening perceived usefulness. Future research recommendations include technological advancements and application expansion, interdisciplinary collaboration, long-term benefit assessments, and the development of policy and practical guidelines. This study aims to provide valuable information for the field of school health and injury management to ensure that students enjoy a safer and healthier environment during their learning process.
