In this paper, a smart attendance system for students attending school is proposed. The proposed attendance system is based on radio frequency identification (RFID) technology to facilitate automation and convenience. The proposed RFID attendance system (RFID-AS) should be used by school administration to ensure safety for students, as well as for grading and evaluation purposes. After careful study, passive RFID technology is selected to be used by the proposed system because of its reasonable cost. The main components of the system are an RFID tag, an RFID reader, Visual Studio [eXpressApp Framework (XAF) tool], and SQL Server to compare the data from the RFID tag with the students’ database to record attendance automatically. A graphical user interface (GUI) is developed using Visual Studio (XAF tool) to allow parents and school faculty to log in and browse the students’ records. Students will pass the classroom door, which will have an integrated RFID reader device to read their RFID. The paper discusses the design of the solution as well as the testing scenarios.
