The project entitled “ATTENDANCE SYSTEM USING FINGERPRINT” is to provide an authentified attendance system for Roots Industries Limited. This software provides various information, which is useful for user as well as administrator. This software can be used as a whole in organization, or can partly used as separate modules, whenever needed.

The project deals with capturing the thumb impression of the employee through the thumb scanner and authenticates with the already registered impression. Attendance will be marked for the matched employee. With the in-time and out-time, the total hours worked by the employee in a day and days worked for the month is calculated. The salary is calculated from loss of pay, basic pay, allowances, and deductions.

One of the main advantages of this software is its user friendliness and validation can be done for each and every employee entered. New entries can be registered very easily and if not needed then it can be deleted from the software.

The environments being used are VB.NET as front end and SQL Server as back end. This project is developed in the Operating System, Microsoft Windows XP.

CHAPTER I

INTRODUCTION

This chapter contains the problem definition, about the system environment and the organization profile which gives details about the company.

PROBLEM DEFINITION

OBJECTIVE AND SCOPE

The main objective of this project is to do the following operations

  • Thumb impression Comparisons
  • Attendance Calculation
  • Payroll Calculation

The scope of the project is to capture and verify the thumb impression of the employee. And also provide effective means to calculate attendance and payroll for the employee by using thumb impression.

This project would greatly help in simplifying the manual attendance calculation and payroll calculation.

PROBLEM DESCRIPTION

This project makes use of fingerprint to authenticate the employee. This project makes use of the physical hardware device, the thumb scanner to capture the thumb impression of the employee.

The Administrator registers the details of new workers. He also registers the unique thumb code of the employee generated by the Thumb scanner. This thumb code is generally an alphanumeric code and it is stored in the database.

The employee uses the thumb scanner when he enters and leaves the work place for attendance marking. The generated code is matched with the stored thumb code in the database.

The attendance is marked for the corresponding employee where thumb code matches with the generated ones. If there is no match with the thumb code then the administrator will take in charge to check whether the person is a new employee or not.

The time duration between intime and outtime is calculated and it is stored as hours worked by the employee. Each time when the outtime is marked the duration is calculated and hours worked (field) is updated.

The employee may take leave. The leave taken by the employee is calculated as loss of pay for him. It will be used to calculate net pay for the employee in the payroll calculation.

During salary calculation the monthly attendance of the employee, loss of pay, the allowance such as HRA, DA and deductions such as PF, LIC are considered.

4.2 SYSTEM IMPLEMENTATION

STEP 1: Start the process.

STEP 2: Employee places the thumb on the thumb scanner.

STEP 3: The scanner generates thumb code corresponding to the thumb impression.

STEP 4: This code is matched with the already stored code in the database.

STEP 5: If there is a match, the employee ID and employee name is retrieved from the employee table and present time is marked as intime or outtime correspondingly to the entry or exit of the employee.

STEP 6: If no match occurs then “No Record for the Employee” message will be displayed.

STEP 7: The difference between intime and outtime is marked as hours worked and each time when the employee goes out the hours worked field is updated in the database.

STEP 8: According to the total no of hours worked by the employee ,attendance is marked (as half day or full day).

STEP 9: The total number of days worked in the month is calculated.

STEP 10: Accordingly no of leave taken by the employee is noted.

STEP 11: If the casual leave and medical leave taken by him is more than the allotted leave then it is considered to be the loss of pay.

STEP 12: The allowances such as HRA, DA are added and the deductions such as PF, LIC, loss of pay are deduced from the basic pay and thus the net pay is calculated.

STEP 13: To include a new employee the administrator has to be logged in using the login-id and password.

STEP 14: He registers the employee details such as employee-id, employee-name, date-of-birth, date-of-join, mobile-no, sex and address.

STEP 15: Stop the execution.

CHAPTER V

CONCLUSION

The use of computerized approach in employee recognition reduces lot of time and provides more security and accuracy. The system is very flexible and user friendly. Further enhancements can me made with less effort. Modification can be made to the system with out much difficulty.

The system is easy to access, understand and recognition of thumb impression enables the administration to do the attendance calculation work with less effort. There is a scope for enhancement of the project in terms of advanced technologies and uploading facilities.

FUTURE ENHANCEMENTS

The adopting of Object Oriented Design (OOD) methodology in handling the software development makes it easy to accommodate changes, maintain, enhancements in future and upgradeability.

The use of Database methods in this project enhances easy maintainability. As these mechanisms are reused, the development of newer modules and upgrading of the software to newer technology is effortless and straight forward.
