Attendance and overtime record keeping - West Bengal Shops and Establishment

1)Does the labour inspector accept soft copy of attendance register?
2)If answer to the above question is yes, does it have to be in any particular format? (As per WB Shops an establishment Rules)
3) Does Biometric online data tracking need State Government's or any authority's approval?
4)If biometric system is incorporated, is there a need for manual registers also? Or either of the two would suffice.
