Our project consists of a RFID based attendance system that allows for
automatic attendance marking by using RFID tags. Every student is
provided with a unique authorization tag/card that is used to record
A lot of time is wasted in schools and colleges for manual attendance
procedures, in such cases our system provides an instant and automated
attendance marking system. Every authorized student is provided with a
unique RFID tag/card with his/her details fed in it. The tag consists of
a built in integrated circuit that stores this data through modulating
and demodulating transmitted radio frequency signals.
The data thus stored in this card is the unique identification of that
person. As soon as the card is placed in front of the RFID reader, the
data in it is read and attendance for that student is registered. This
is done with the help of an 8051 microcontroller interfaced with the
If it is a registered student, then a confirmation is displayed on an
LCD screen, else a rejection message is shown that denies the
attendance. All student attendance status can be later obtained from the system when
the status button interfaced with the microcontroller is pressed. This
saves a lot of time and effort in student attendance registration.
This system can later be further improved by adding attendance sms to parents or using bio-metric attendance systems.
