SUMMARY
Fingerprint verification is one of the most trusted personal identification methods in the field of biometrics. with the rapid development of the fingerprint scan, the number of its application were not offered so far including time attendance system etc in this fingerprint attendance management system developed and implemented system. This is the basis of fingerprints and serial communications port method solves the problem of false attendance and maintaining the registry. This can make attendance users more easily and effectively.
INTRODUCTION
While the move toward digital era accelerates every hour, biometric technologies have begun to influence everyday lives more and more. Biometric identity verification technology through characteristics such as fingerprints, facial, Iris, retina patterns, hands, voices, handwritten signatures, and so on. These methods, which use physical data, receive attention as a personal authentication method, which is more convenient than traditional methods, such as a password or ID cards. Biometric personal authentication uses data obtained from measurements. Such data are unique to humans and remains so throughout life.
This technology was applied to control access to objects with a high level of security, but are now widely used in information systems, such as networks, e-commerce and retail applications. In these technologies, fingerprint is the most mature and popular technology of biometrics is used in automatic identification. In the beginning, the fingerprint confirmation made use in military matters and criminal identification. But now the technology is also used in some other applications such as access control to installations with a high level of security, credit card authentication and identification staff
The existing system
Most systems use paper attendance based on the methods of selection and calculation of attendance, and this manual method requires a lot of sheets of paper and stationery material. Earlier, very little work has been done on the problem of school attendance monitoring. Some programs have been developed previously for tracking attendance. But they require manual input by staff. Thus, the problem remains unresolved. In addition, the idea of attendance tracking system using facial recognition technology, have also been proposed, but it requires expensive machinery still does not receive the required accuracy.
Requirements for System Design
Fingerprint authentication:
Attendance management is an important part of the company's management system. This can be in contact with the salary of the employee, the company's efficiency, and even affect the company's business image and staff morale. Thus, the problem of prudent, efficient and scientific management of staff attendance was all companies face the issue. Traditional management styles in attendance included handwritten captions, maps of Bell, magnetic cards, IC cards and RF card machines attendance. These styles can not avoid the substitute check only because people can be separated from the cards.

The Use Of Off-line Transfer Technique:-
There are basically two types of fingerprint attendance management system on the market. One of them is a system of on-line fingerprint attendance management and other off-line fingerprint management system for attendance. Online system must always be connected to a PC or workstation and all templates of fingerprints "people to be tested must, stored in the database in a PC or workstation. Therefore, the match fingerprints needs to be supported against the PC. This attendance management system easy to paralysis if fingerprint attendance machine failures, transmission line or PC. After several connection systems for the formation of the network, will be added to the load and response time of the system.
And one off-line fingerprint attendance management system can finish the whole process, including image capture fingerprint, removing trivia, storage and compliance. All operating matching fingerprints does not need the support of the PC and the PC burden is lightened. The same system can be connected to form a network of 485 and finally connect to the central PC control system. So off-line systems are widely used in many cases. And disadvantages of this system is that there should be control PC a bit, and it's hard to lay the lines where the topography is bad.
