Design of Student Attendance System based on 2.4Ghz RFID Technology

Abstract

In order to improve school management of student attendance, based on the 2.4Ghz card, using RFID technology and server back-end technology, A set of student entry and exit attendance system has been designed. The current positioning method generally used distance fitting model based on RSSI. This method has very high accuracy, but the accuracy of calculation results is highly affected by the environment and the amount of data required for calculation is very large. Usually, the data need to be transmitted from the terminal to the server for processing witch increases calculation complexity. The paper proposes an algorithm based on least squares semaphore, this algorithm greatly simplifies the calculation complexity and improves the calculation efficiency.
