Absrtact: Radio Frequency Identification (RFID) technology is widely used in real life. There are many applications in various access control systems, anti-counterfeiting, public transport, medical and other fields. It is a non-contact automatic identification technology based on radio frequency communication, and the main content of Home-School Communication is the daily attendance management of students. The daily attendance data of students is an important material of teaching management, which not only concerns the personal interests of students, but also relates to the normal operation of school education and teaching tasks. Therefore, the development of home-school communication based on RFID technology helps to ensure the accuracy of attendance data and improve the level of education and teaching management, which has great benefits in many aspects of school management. To solve the above problems, the research idea is that children wear tags through the reader, which transmits the received information to the server, and the server sends short messages to parents'mobile phones, informing parents and children when to enter or leave school.
Key words: RFID technology; home-school communication; attendance management

,也涉及到学校教育教学任务的正常运行。针对上述问题的研究思路是,告知家长孩子于几时进校或离校。学生的日常考勤数据是教学管理的重要资料,服务器端发送短信至家长手机,提升教育教学管理水平,开发本次基于RFID技术的家校通有助于确保考勤数据的准确性,孩子佩戴标签通过阅读器,在学校管理的诸多方面都有很大的益处。阅读器将接收到的信息传递给服务器端,而家校通的主要内容是对学生日常的考勤管理
