Development and application of check on work attendance based on RFID
Abstract: Many current when the teacher in class needs to be named or sign in, one is the teacher in class time delay, the second is low could make the enthusiasm of students, so the design decisions on the basis of what we have learned the university four years, do a check on work attendance system based on RFID, so convenient teacher's sign in name, also at the same time let the students consciously to class and sign in to the classroom. Contains the RFID classroom read card, data upload and receiving terminal and the host. This topic has three need to complete the task: 1, the configuration of RFID system of check on work attendance, testing and screening, choose the most reasonable and simple design, so that more human attendance system; 2, upload data, the data obtained will be intact transmitted to the host, which make the system users can more clearly observe attendance; 3, data display, record and management function design, is one of the most important link, it is also the difficult point in attendance system, involves the VS, databases, and VB.NET language.
