Using Biometric Device How to calculate Over time

Hi
using Bio metric Device How to calculate Over time. Is any one completed HR activities with Bio metric device attendance and overtime. How to achieve it?
Pls help.

Thanks

Any one please reply

hello. can you explain your question . is it about integrating the biometric device or just calculating the time ?

Not integration. How to calculate Over time while using Biometric device.
Coz, Normally OT is calculating thru TimeSheet. Then How we calculate Over time.

why dont you just wreate a server script before inserting a new attendance( biometric device) and calculate whatever you want

I understand sir. I am asking how to manage Over Time in existing application with Biometric. Is we need to create app for this.
