INTRODUCTION
Biometric system is an automated method of recognizing a person based on his physiological and behavioral characteristic. It is a system that verifies human identities through characteristics such as fingerprints, faces, retinal pattern, palm, etc. This technology is being used in several applications such as access control for high security, credit card usage verification, and employee identification.
Problem StatementTraditional staff’s attendance in AIT is taken manually, done by using attendance sheets given to an officer, in charge of monitoring the staffs’ work place attendance and the time they spent on their particular assignments. Unfortunately this practice is revealed to be ineffective as personnel often find their way around it. Resulting in an inaccurately and efficient attendance record keeping from the AIT administration, lectures and other staffs are often paid for time they did not spend on duty. Resulting in bad professional behavior and financial lost.
Background of the study
Biometric system is a technique that has been used for many years; The use of this system to monitor the attendance of staffs has revealed itself very successful as it increases the staff accountability and boosts the workers toward good professional conduct.
It is being now in numerous field including financial, medical, commerce and customer application as a secure and effective authentication method. Fingerprint authentication has been used for long time and bears more advantages than other biometrics. It has been verified through various applications in 1924. three basic patterns of finger

DESIGN CONCEPT
The experimental design of the biometric fingerprint system is developed using PROTEUS software before proceeding to the construction and analysis ,the design and the component selection are validated by simulating the different sections of the design
• Fingerprint module
A fingerprint module is an electronic device used to capture a digital image of the fingerprint pattern. The captured image is called a live scan. This live scan is digitally processed to create a biometric template (a collection of extracted features) which is stored and used for matching.
Fingerprint Scanner
DESCRIPTION OF COMPONENTS
Liquid crystal display is used for displaying the messages. It is in 4bit mode and it is connected to the microcontroller.
LCD 16*2

microcontrollerIt has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator and USB connection. It contains everything needed to support the microcontroller.
BUZZERThe Piezo Audio Transducer that generate a range of audible tones and frequencies when energised with 5 Volts is used to generate a sound after the finger print scanning as taking place.
Piezo Audio Buzzer
LEDS are semiconductor light that are used to identify whether the print has been pressed. Two types of LEDS are used in this project. The green LED is used to indicate that the print has been saved while the red LED is used to indicate that the print has not been saved.
VOLTAGE REGULATOR
In order to regulate the supply voltage and avoid excessive voltage theLM7805 voltage regulator from the LM78XX series is used to limit the supply voltage at 5V for the microcontroller and the rest of the system.

Summary of study
The study presents the design and simulation of biometric fingerprint system of the Accra Institute of Technology. The study presents a description of the components and equipment required to construct an effective biometric system for the AIT attendance. The design system was modeled and simulated using PROTEUS 8 PROFESSIONAL. After testing the complete project, the system reveals itself to be working correctly.
When a person presses the finger on finger on fingerprint scanner, it gives high and low logic digital signal to the microcontroller after pressing switch 2. This controller is programmed in such a way that it stores the digital data.When the switch 1 is pressed again, it ask for fingerprint scanning if this data matches with the previously stored fingerprint data, it generates an output signal that displays the information on the LCD display.
It is also possible to delete the scanned finger by pressing the switch3 and also, if any unauthorized person tries to access the
device, this system gives an alarm.
CONCLUSION
This project work dealt with the design and simulation of a biometric fingerprint system that can be used to eliminate absenteeism and impersonation. The developed system allows the user to have his/her authentication password in order to eliminates time-related disputes and maintain good attendance records as a result.
From the design and simulation of the system presented, the system is able to insure the account department an effective tracking of the time the staffs are supposed to be paid and to monitor the reporting time and the clocking out of the permanent staff. These objectives of this thesis were successfully attained. It eliminates paper for the attendance recording and facilitates the creation of fair payrolls.
RECOMMENDATION
• The system can be connected to a wireless structure that will alert the number and the names of staff and lectures available on campus a particular day at a particular time.
• The system can also be connected to C3000z adapter biometric fingerprint that can register time and attendance system for the AIT campuses through a mobile phone.
