Design and implementation of RFID based attendance system

Abstract

Attendance is taken at various places like schools, colleges for students and login logout time for employees in industries and offices. The existing system is done on paper and it consumes lots of papers and it is of manual work. It has less accuracy. In order to reduce the usage of paper RFID based attendance system is used. It is an automated attendance system where Rfid tags are used. This is the easy way to take the attendance without any physical contact. In this project we use RFID Reader, RFID Tags, LCD display, which are interfaced withATMEGA8 Microcontroller. The Rfid tags are given to the students, with their roll numbers as their tags. When the tag is placed near the reader, the data is transferred to reader due to the radio frequencies. Reader then transfers data to the microcontroller. Microcontroller checks for the data continuously, if any data is received, microcontroller compares the data in data base. It eliminates the duplicate entry of data and reduces errors in time and entries.
