The system performance problem is the key factor that causes the tragedy.

Solution:

1. Clear all attendance data in the attendance machine, because this may be caused by the crash of the built-in database of the attendance machine.

2. Initialize the attendance machine, and then re-transmit personnel data and photos to the attendance machine.

3. Observe whether the punching is normal, and if it is normal, it will be OK!

4. Pay attention to upload the attendance data on the attendance machine to the computer as soon as possible every time to avoid machine failure and loss of attendance data.

5. If you do this, you can contact Hanwang customer service directly to solve it without a list!

I hope it helps you!
