Representative timing frameworks are time framework utilized by organizations to precisely record the quantity of hours worked by every worker on week by week premise (John Furnem, 2007). The clock has developed with time and the foundation still needs a framework that they can utilize worker payroll and guarantee that the workers are paid for every hour they met expectations. Today, representative utilization swipe cards with a negative stripe through an opening that peruses their name and records the time, each time they check in or out, much like the old punch clock arrangement of long back. Toward the end of a work week, the executive processes the aggregate hours worked for each representative and prints it out on a spread sheet. This frees the payroll arrangement of human mistake, making it considerably more effective.

As indicated by Jain (2004) each human has an extraordinary finger impression picture that can't be imitated. Therefore, making the unique mark innovation more proficient, reliable, simple and solid than different qualities of biometrics. It likewise obliges a genuinely little size of memory to store biometric layout. Not at all like the voice identification, amid harmattan period the representative's voice can be coarse because of chilly, subsequently adjusting the voice example and access foreswearing, same case with face identification, when the worker begins maturing or encounters skin responses like pimples it prompts a bargain in the framework. On account of mark it can be effortlessly manufactured, while retina checking is expensively arranged.

The Federal University of Technology, Minna does not make utilization of a modernized representative timing framework. The establishment sets aside a few minutes clock framework, however efficient, is not so much impeccable in light of the fact that it is sporadic. In some cases, the attractive strip on the cover of a card may get harmed on account of punch card system. At the point when the representative swipes the card, the machine may not enrol it. Such insufficiencies are amended in the machine time clock system. This venture guarantees that workers will constantly require an approach to stay informed concerning their time and associations will have the capacity to screen and record a representative's chance to guarantee greatest achievement.

1.2       STATEMENT OF PROBLEM

The problem is centered on how to design and implement a computerized employee clocking system for Federal University of Technology, Minna. From the study layout the problems discovered are; inadequacies of the manual time clock system, and easy impersonation of staff.

1.3     SIGNIFICANCE OF STUDY

The significance of the study is;

To correct the inadequacies of the manual time clock system, to regulate unauthorized entry into the building. To keep track of the time and ensure logical ways to monitor and record an employee's time and to provide maximum productivity and cultivate punctuality of employees.

1.4   AIM AND OBJECTIVES OF STUDY

The aim of this study is to put to rest the cumbersome and hectic nature of employee time clocking system. The objectives of this study are:

1)  To study the existing clocking system.

2)  To develop a fingerprint identification based clocking system.

3)  To test the performance of the developed system with arbitrary input parameters.

1.5      SCOPE OF THE STUDY

This study is limited to only Federal University of Technology, Minna institution to the non academic staff. Though, the scope above is in such a way that the study can be carried out in one and only one way that is, computerizing the employee clocking system. This will help to eliminate the inherent problems encountered by the management of this institution.

1.6 LIMITATIONS

The factors that militated against this study in the course of gathering facts and figures, went a long way in limiting the intended scope of this study as a result of these, setbacks were encountered.

If the surface of the finger gets damaged and/or has one or more marks on it, identification becomes increasingly hard. Also wet and dirty hands are difficult to enroll thereby producing false acceptance or rejection.
