It gets difficult to keep track of the time keeping practices in a premise where there are many individuals. Biometric face recognition time attendance system proves useful in such a situation. It can mark the time and daily presence of the individuals in a premise and generate detailed reports on the same at regular intervals.

Face recognition time attendance is an advanced biometric application. It requires the user to enroll the facial details of all the employees in a work place. Enrollment procedure consists of storing the unique and permanent facial characteristics of each individual in the database as templates. After enrollment, the enrolled individual only needs to look before the camera. His identity will be verified by the system and attendance will be marked on his behalf.

There is hardly any scope of error in the entire process. Vendors of a biometric face recognition time attendance system promises utmost accuracy. However, no security is fool proof.

If the biometric face recognition time attendance system takes only a little out of them into consideration, there are higher chances of False Accept Rate. Unauthorized individuals may be allowed to mark attendance on behalf of the authorized employees.

*Considering too many nodal points at the time of verification may lead to high False Reject Rate. Variations in the pose at the time of making a transaction as compared to when enrolled also affect the transaction. If the head is slightly tilted or nodded, the biometric face recognition time attendance system may fail to identify the individual.

Possibilities of an error prevail in the above mentioned circumstances. However, modern face recognition time attendances are designed keeping all the above possibilities in mind.
