Dear Swapnil,
Referring to my previous post in response to yours, I emphasize that it is the primary responsibility of the contractor to maintain the muster roll of his workmen, which is also a statutory compliance norm under CLRA, 1970.
Tracking Attendance with Biometric Systems
Now, as the principal employer, the law does not stop you from tracking the attendance of the workmen deployed by your contractor, and you may even mechanize the process.
As desired by your directors, you may certainly opt for a biometric system as the attendance tracker, which will also serve as a security check at your premises.
I can share my experience with you that we, as a contractor, had deployed manpower with a global IT company, and the attendance of our employees is tracked via biometric access cards at the premises of our client.
The muster roll format will show you whether any workman was present on his/her duty on a specific date, and it will not include the in and out times that you can track from the biometric system. This will help you monitor whether the working hours are properly utilized or not.
The only point you need to ensure is that your contractor maintains the muster roll for the attendance of the workmen as a statutory compliance norm.
Regards,
