This paper proposes an intelligent attendance design scheme based on a distributed three-tier architecture. This scheme uses the TCP/IP network to build the communication link of the attendance terminal, the control host and the server, and realizes the induction and identification of the attendance identity by running the intelligent attendance software. The technical scheme proposes the top-level design of the educational administration system of vocational colleges in the context of the digital campus. Based on the J2EE platform, the main code is developed using the Java programming language and server-side Java technologies (such as EJBs, Servlet, JSP, JNDI, JDBC, and RMI, etc.).
