This document summarizes an automated attendance monitoring system using biometric fingerprint scanning. The system aims to address drawbacks of current manual attendance systems like wasted time, paperwork, and the ability to fool teachers. It uses an Arduino board connected to a fingerprint scanner, LCD display, keypad, and WiFi shield to automate attendance tracking. Student and staff fingerprints are enrolled in the system and then scanned each day to mark attendance. Attendance data is sent wirelessly to a server via the WiFi shield. The system allows for automated internal mark calculations and notification of parents via SMS. It provides a more efficient, secure, and foolproof alternative to current manual attendance processes.

1. AUTOMATED ATTENDANCE
MONITORING SYSTEM

3. CURRENT ATTENDANCE RECORDING
SYSTEM
The current system of recording attendance has a huge drawbacks
• It wastes the valuable time
• It involves loads of paper work
• Can fool teachers when roll call taken
• Involving tiring works of updating attendance
• Eats your brain when calculating attendance percentage
NO MORE HEADACHES. SWITCH TO BIOMETRIC ATTENDANCE SYSTEM

4. WHY BIOMETRIC ATTENDANCE?
Radio Frequency Identification (RFID) based time and attendance
systems have a big drawback: buddy punching.
Buddy Punching?
A person delayed on his way to work can hand over his tag or ID
card to his colleague so that his presence is marked in the
database even though he is absent.
Biometric time systems eliminate buddy punching

6. ONE TIME ENROLMENT PROCESS
• The staff as well as the student requires one time enrolment process.
• For this one time a system is required.
• The individual must first enter their unique id.
• Press the desired finger on scanner 3 times as and when instructed.
• Dispatch module after the process.
• Insert 9V battery for its power supply.
• Now ready for daily authentication process.

7. COMPONENTS USED

8. 1. ARDUINO UNO
• The Arduino Uno acts as an interface to the devices such as Wi-Fi
shield, GSM shield, Raspberry Pi, Keypad, LCD Display, and the
server in which we maintain the database.
• An Arduino is
• A single board microcontroller
• Inexpensive
• Comes with simple IDE

10. 2. ADAFRUIT FINGERPRINT SCANNER
• Used for security purposes
• Can easily detect and verify fingerprints
• Uses high powered DSP chips that does
• Image rendering
• Calculation
• Feature Finding
• Searching

12. 2. ADAFRUIT FINGERPRINT SCANNER
• Can enrol new fingers directly to the on-board FLASH memory
• Provide two LEDs. A green and a red
• Set the red to HIGH in the code generated
• Green active when finger placed
• Rest of time Red will be active
• The enrolment program is uploaded in the Arduino

14. 3. RASPBERRY PI
• Raspberry Pi is a credit-card sized single board computer.
• Install a Raspberry Pi OS onto an SD card(minimum 4gb). The
New Out Of the Box Software (NOOBS) is the recommended one.
• Mount Arduino on Raspberry Pi.
• Thus the program is inserted into the OS and makes it run
automatically whenever power supplied.
• Hence device becomes automatic.

16. 4. ARDUINO WI-FI SHIELD
• Arduino Wi-Fi shield connects the Arduino to internet wirelessly.
• We need to program it to send the fingerprints taken to the
server via the shield.
• Initially the staff is required to enter the day, period (using
keypad) and his/her fingerprint as well.
• After checking with database, the module is passed to students
to enter their fingerprint.

18. 5. KEYPAD
• Used to enter the day and the period
• Information passed to database and checks to which staff the
attendance should be updated and the percentage to be
calculated
• Connected with Arduino
• Programming done with Arduino compiler

20. 6. GSM/GPRS SHIELD
• The Arduino GSM Shield allows an Arduino board to connect to
the internet, make/receive voice calls and send/receive SMS
messages.
• The shield uses a radio modem M10 by Quectel. It is possible
to communicate with the board using AT commands.
• Insert a SIM to send SMS to the parents automatically.
• We do programs and upload it to the Arduino board to send
SMS automatically

22. 7. LCD DISPLAY
• We use JHD204A display.
• Whenever the finger is pressed his/her id will be displayed for
confirmation.
• The inputs given are also shown in the display.

24. 8. WEB INTERFACE FOR STAFFS
• Can also be managed manually.
• Each staff is given a unique username and a password.
• They can view the student details, can manually send Mail or
SMS, and they can see the attendance percentage of each
students.
• They can also download the attendance details in excel sheet
form and take printouts if needed.
• Thus fully automated and is very easy to calculate the internal
marks of students.

27. CONCLUSION
• Internal calculation can be done with more ease
• No more paper works involved
• The system
• is fully automated
• is a time saver
• is fool proof from early punching, late punching and buddy punching
• ensures better security
• is cheap, affordable and flexible
