Arduino Based Attendance System Using RFID Tag
The main objective of
this project is to record the attendance of students using RFID tags. Each
student is provided with his/her authorized tag to swipe over the reader to
record their attendance.
In classrooms, time is
wasted in roll calls as it is done manually. In this proposed system,
authorized student is given an RFID tag. This tag contains an integrated in built
circuit that is used for storing, processing information through modulating and
demodulating of the radio frequency signal that is being transmitted. Thus, the
data stored in this card is referred as the identification/attendance of the
person.
Once the student places
the card in front of the RFID card reader, it reads the data and verifies it
with the data stored in the microcontroller from AVR family. If the data
matches, then it displays a message on the LCD confirming the entry of that
student else displays a message denying the attendance. The status of a
student’s attendance can be retrieved from this system by pressing the status
button interfaced to the microcontroller. Hence, a lot of time is saved as all
the students attendance is directly stored in the data base.
The project can be
further enhanced by adding features like sending an SMS of the daily attendance
of students to their parents. It can also be enhanced by using a finger print
module in place of RFID module that has certain drawbacks of tags be misused.
