Biometric fingerprint reader is a scanning device on which employees of organizations swap their fingers for biometric identification. Biometric fingerprint reader is also used to restrict access to the sensitive data in organizations. Nowadays many organizations use biometric fingerprint reader for daily attendance, which is further helpful when calculating the employees’ salaries and payrolls.
In order to make biometric fingerprint reader function effectively and efficiently, fingerprint of each employee must be enrolled with the database. After the fingerprints are enrolled, and when an employee swaps finger, the image of the fingerprint is matched with the one stored in the database. If the fingerprint matches, the biometric fingerprint reader allows access to the classified data, or marks the attendances of the employee along with the date and time.
