Time & Attendance 

Mark Attendance using Fingerprint Technology 

Here's how it work:

1. Enrollment: Authorized users have their fingerprints scanned and stored as digital templates in a secure database. This enrollment process typically happens during system setup or when granting access to a new individual.

2. Fingerprint Capture: When someone seeks access, they place their finger on the scanner's surface.

3. Image Processing: The scanner captures an image of the fingerprint (using capacitive, optical, or ultrasonic technology as described previously).

4. Template Extraction: The scanner extracts a digital representation (template) of the captured fingerprint data, focusing on the unique ridges and valleys.

5. Matching the Database: This extracted template is then compared against the pre-enrolled fingerprint templates stored in the access control system's database.

Recording Attendance:

1. Match Success: If there's a sufficient match between the scanned template and a stored template, the system automatically records the current time and date. This signifies the employee's arrival or departure time. 

2. Match Failure: If there's no matching template or the match quality falls below a certain threshold, access is denied. An alarm might be triggered, or an alternative authentication method might be required.

Benefits:

• Enhanced Security:

• Fingerprint scanners eliminate the possibility of "buddy punching" (clocking in/out for someone else). This ensures accurate attendance records and reduces payroll discrepancies.

• Improved Accuracy: Fingerprint scanners eliminate human error associated with manual sign-in sheets or forgotten badges.

Limitations:

• Initial Investment:Implementing a fingerprint scanner system may require an initial investment for purchasing and installing the scanners.

• Sensor Accuracy: Scanner performance can be affected by factors like dirty or wet fingers, potentially requiring re-scans.
