Fingerprint Attendance

System

Mohamed Basheer K PM100189EC

INTRODUCTION Automates attendance procedureHand-held device which can take attendance without intervention of teacherDevice can be passed during lecture timeStudents can place their finger and mark their attendancePC Application will help the teacher to manage device

MotivationNormal attendance procedure of educational institutions

Wastes some amount of time Can cheat using proxy method

Corporate  environments Use similar technologies

SURVEYAttendance procedure of educational institutionsAutomation of attendance procedure

Using RFID technology Need to carry tags

Using Biometric technologyImplementation methods

Computer based Not possible in academic environments

Portable Real-time verification

PROPOSED SYSTEMTwo sections

Portable DeviceGUI application

Hardware part consists of

MicrocontrollerFingerprint moduleGraphic LCDMemoryRTCButtons and LEDs

GUI application Uses USB interface Only for faculty Manages entire data in the device Students’ list can be downloaded into the device

from an excel file Attendance data can be read to the host

computer Attendance data can be exported as excel file

DETAILED DESIGNMicrocontroller

PIC18F4550 40 pin 2v to 5.5v operating voltage range 32KB flash, 2KB RAM Oscillator

48MHz external 8MHz external

USART, SPI and I2C ICSP via two pins USB V2.0 Ideal for battery powered

applications Power managed modes Dual clock operation mode

Fingerprint Registration

More than one batch is supported by the deviceStudents can register on different daysFaculty can add additional students

Changing fingerprint also possible

Only faculty can select the batch

Device can ask about new hour if it is in same day

Attendance marking Three conditions

Status indicator, Uses a double colour LED
