Using the same biometric device for time attendance and door access control

Using the same biometric device for time attendance and door access control. Using the same biometric device for both time attendance and door access control is possible, but it comes with potential challenges and considerations.

Here’s an analysis:

Advantages:

1. Cost Efficiency: A single device reduces the cost of purchasing and maintaining separate systems for access control and time attendance.
2. Ease of Use: Employees only need to interact with one device, simplifying operations and reducing confusion.

Challenges:

1. Mixed Data:
   • The device will log every entry and exit for door access, which can create a large volume of data that includes unnecessary logs for time attendance purposes.
   • Differentiating between attendance logs (e.g., clocking in/out for work) and access control logs (e.g., entering/exiting during working hours) might require careful filtering in the software.
2. Log Overlap: If employees frequently move in and out of the room, the logs may become cluttered, making it harder to analyze attendance records accurately.
3. Access During Non-Working Hours: If employees access the room outside their shift, it might create discrepancies in attendance records unless properly managed.

Recommendations:

1. Separate Devices (Optional): For optimal accuracy and reduced complexity, consider using separate devices for time attendance and door access if the system becomes too difficult to manage.
