Biometric Time Attendance & Door Lock

A Biometric Time Attendance & Door Lock system is a sophisticated security and workforce management solution that utilizes unique biological traits of individuals for identification and authentication. This integrated system serves a dual purpose: accurately tracking employee attendance and controlling physical access to designated areas.

Core Functionality:

• Biometric Recognition: The system relies on biometric sensors to capture and verify unique biological characteristics. Common biometric modalities include:

  • Fingerprint Recognition: The most widely used, it maps the unique ridge patterns of a person's finger.

  • Facial Recognition: Analyzes distinct facial landmarks and structures for identification.

  • Iris/Retina Scans: Maps the intricate patterns in a person's iris or retina for highly secure applications.

  • Palm/Finger Vein Recognition: Uses infrared to detect vein patterns beneath the skin.

  • Voice Recognition: Identifies individuals based on unique vocal characteristics.

• Enrollment: Users are initially enrolled by scanning their chosen biometric feature. This data is then converted into a unique digital "template" (not the raw image) and stored securely in a database.

• Authentication: When a user attempts to gain access or clock in/out, they present their biometric feature to the sensor. The system compares the live scan to the stored template. If a match is found, access is granted, or the attendance record is logged.

• Time and Attendance Tracking: The system precisely records the exact time and date of each successful biometric scan, providing an accurate audit trail of employee clock-ins, clock-outs, breaks, and overtime. This data is then used for payroll processing, labor law compliance, and workforce management.

• Door Lock Integration: The system is directly connected to electronic door locks. Upon successful biometric authentication, a signal is sent to the lock, allowing the door to open. If authentication fails, the door remains secured.
