In modern time, for the double-income families, parents are usually busy in work, and children stay at schools. After children are sent to the school, parents are anxiously concerned with the children’s situation and performance at schools. Therefore, this study focuses on how to integrate RFID (Radio Frequency Identification) technology with Microsoft SQL Server 2008 database to implement an information system used to monitor student attendance, school entrance, and transaction records. By use of RFID technology, the students’ attendance, students’ in-out the school gate, class attendance, and class location can be monitored by teachers through the classroom computers linked to the information system so that teachers can immediately know the status of student attendance. Therefore, teachers or administrators can grasp students’ status by querying through the information system so that the broadcast time is reduced to find students.
