@ Roselia,
Good afternoon!
First of all, I would like to suggest starting a new thread if your query is not related to the current thread.
Understanding Your Current Attendance System
For e-attendance, you may need to learn about the current attendance system in your company. It might be that people in your company log in every day to mark their presence on some kind of software, and that may be the reason your boss asked you for e-attendance. It is possible that you have multiple locations in your company, and they are doing their electronic punching, which may be mapped to your location. You can take an attendance log out of this.
Please describe your current attendance system. As an HR professional, you are also an employee. How are you marking your presence? This will help us provide more views on your query about "e-attendance."
Revert if you need more guidance on this.
