Dear Gauri,
After going through your brief statement, it is clear that your unit is covered under the Factories Act and thus, you are required to maintain the muster roll in the prescribed format as provided by your State Factory Rules. Regarding the system of tracking the attendance of the workers/employees through a fingerprinting machine, it is submitted that these types of systems do not have any statutory force or acceptance until the approval of the Government/Chief Inspector of Factories of the concerned State. Therefore, until then, you are advised to maintain the attendance register according to the rules of your State.
