Biometric attendance systems seem to be an emerging trend nowadays in public and private workspaces for stringent attendance recording purposes. With growing vulnerability and cost issues concerning passwords and tokens, the market is witnessing an increase in the demand for biometric-based identification in workplaces and institutions to monitor employee attendance and efficiency. However, unlike traditional attendance systems, Biometric attendance systems may cost a little more, but the benefits are immense.
So, the question comes to mind: what is an ideal Biometric time & attendance system that will suit to the organization, as the modality comes in many forms, such as fingerprint, face, iris, voice, palm vein, etc? Well, honestly, the answer is no single modality will suit or perfectly fit to the requirements. The Biometric Attendance System (BAS), which has both contact and contactless options or has more than one modality, will best fit the needs and will remain in the market.
Benefits of multi-Biometric attendance system
Firstly, it provides the flexibility for an organization to choose the modality depending on its operational needs and employees’ check-in and check-out process. It is not bound to a single Biometric. If one modality fails to identify, or for any other reason does not recognize, the other modality helps the user to check in or out at the location without any problem.
Secondly, it provides flexibility and leverages the user by allowing access via mobile platforms (Windows, Android Mobile, iOS, etc.), as facial recognition comes to mobile smartphones. Because the face is the only modality that does not require any special hardware, like a fingerprint scanner, any smartphone with a built-in camera can perform this operation. So it becomes more convenient.
Thirdly, it provides a greater level of accuracy and robustness. A multi-biometric attendance system provides higher accuracy in decision-making by combining more than one trait from different sensors. In this way, it also creates a robust system.
Finally, it enhances security by combining more than one modality. It is difficult for attackers to spoof a multi-modal Biometric system. Some organizations require an extra level of security to grant access to certain areas.
To conclude the above, it can be understood that multi-biometric attendance systems provide a certain degree of flexibility and benefits over the uni-modal biometric attendance system. Suppose a user enrolls in the system using several different modalities, and later at the time of authentication, he can select which modality to present depending on his convenience.
