Disadvantages of a biometric system. * The finger print of those people working in Chemical industries are often affected. Therefore these companies should not use the finger print mode of authentication. * It is found that with age, the voice of a person differs. Also when the person has flu or throat infection the voice changes or if there there are too much noise in the environment this method maynot authenticate correctly. Therefore this method of verification is not workable all the time * For people affected with Diabetes, the eyes get affected resulting in differences. * Biometrics is an expensive security solution. * Advantages of Biometrics :

* Increase security - Provide a convenient and low-cost additional tier of security.

* Reduce fraud by employing hard-to-forge technologies and materials. For e.g.Minimise the opportunity for ID fraud, buddy punching.

* Eliminate problems caused by lost IDs or forgotten passwords by using physiological attributes. For e.g. Prevent unauthorised use of lost, stolen or "borrowed" ID cards.

* Reduce password administration costs.

* Replace hard-to-remember passwords which may be shared or observed.

* Integrate a wide range of biometric solutions and technologies, customer applications and databases into a robust and scalable control solution for facility and network access

* Make it possible, automatically, to know WHO did WHAT, WHERE and WHEN!

* Offer significant cost savings or increasing ROI in areas such as Loss Prevention or Time & Attendance.

* Unequivocally link an individual to a transaction or event.
