The process of using a biometric fingerprint scanner for duty usually includes the following steps:

1. System setup and preparation

Equipment installation: Make sure the fingerprint scanner is properly installed and connected to the computer or server system.

Software configuration: Configure the relevant software, including drivers and management systems, to work with the fingerprint scanner.

2. Fingerprint registration

Collecting fingerprints: Before the first use, the fingerprints of each duty officer need to be collected and stored in the database. This usually includes multiple scans to ensure that high-quality fingerprint images are collected.

Data entry: Associate the collected fingerprint data with the personal information of the duty officer (such as name, work number, etc.) and store them.

3. Duty identity verification

Fingerprint scanning: When the duty officer signs in or enters a specific area, he or she places his or her finger on the fingerprint scanner for scanning.

Data matching: The system compares the scanned fingerprint data with the stored data in the database to verify the identity.

Verification results: The system returns the comparison results quickly, usually within one second. Personnel who pass the verification can continue to work or enter the designated area, and those who fail the verification need to try again or contact the administrator.

4. Real-time monitoring and recording

Record log: The system automatically records the time, location and results of each fingerprint scan and generates a log file for subsequent audit.
Real-time monitoring: Managers can monitor the duty situation in real time to see which personnel have signed in, not signed in, or failed to pass the verification.

5. Handling abnormal situations

Abnormal alarm: The system can be set to issue an alarm to notify managers when multiple verification failures or abnormal activities are detected.
Manual verification: In the event of fingerprint recognition failure or device failure, an alternative manual authentication method can be adopted, such as checking identity documents.

6. Data maintenance and update

Regular update: Regularly update the fingerprint database to add fingerprint data of new employees or remove data of resigned employees.
Data backup: Regularly back up fingerprint data and log files to prevent data loss.

7. System maintenance

Equipment maintenance: Regularly clean and maintain fingerprint scanners to ensure the normal operation of the equipment.
Software upgrade: Timely update system software and drivers to obtain the latest features and security patches.
Through the above steps, biometric fingerprint scanners can be used efficiently and securely for duty management, ensuring that only authorized personnel can perform tasks and enter specific areas, while providing detailed records for auditing and monitoring.
