Q.7 Is network connectivity essential for marking attendance

Ans.Yes, as it is an online attendance system. Network connectivity will be essential for marking attendance. Therefore, two types of connectivity are being planned with each attendance terminal; one wi-fi connectivity on NICNET/broadband and other sim based GSM connectivity in the tablet.

At a high level the overall solution has two main components.

(i) Front End System (to be installed at client user end)

(ii) Back End System (attendance servers to be hosted in NIC data centre with connectivity to UIDAI for real-time bio-metric authentication)

The Front End System would be a hardware device like Android tablet or a Desktop PC having client application. Once the user ID (6 digit unique number assigned to an employee) is entered, the application would prompt user to provide the biometric data through finger print/Iris scanner which will be sent through the network connectivity to the backend system.

The Back End System (also called the attendance server) would have functionalities to receive data from the client terminals and send it for real-time Aadhaar authentication. It would also have features for organisation/employee registration and preparing real-time attendance reports in dashboard.

It would be possible to see dashboard reports of each organisation by using sub-domain assigned to an organisation

Q.8 No of bio-metric terminals required
Ans.Every employee will need to enter his 6 digit unique id on the touch screen of the tablet and then present his bio-metric (finger print/ iris) for authentication. This may initially take up to 30 seconds to 1 minute depending on number of attempts required. With some practice and training, the time  for giving bio-metric attendance by each employee may reduce to less than 10 seconds.Therefore one bio-metric terminal may be sufficient for about 30 to 40 employees during 30 minute peak load time. Assuming 50% to 70% employees will be coming to office during the peak timings, one bio-metric terminal can be planned for catering to every 50 employees in the department. Also, multiple machines will be put in the entry gate which can be commonly used by employees of different ministries/departments, waiting time in the queue will further reduce.
Q.9Where to install tablet based terminals? is suggested to install multiple BAS terminals at the entry gates of the buildings where security is positioned round the clock.
Q.10Where to install desktop based finger print devices? is suggested to install desktop finger print devices on Windows desktop PCs connected on LAN (NICNET) in the offices of JS and above and also with section officers for marking attendance of the employees working in the respective sections in order to avoid rush at the attendance terminals installed at the entry gates.
Q.11Who would maintain the attendance terminals, connectivity and attendance software for desktop PCs?
Ans.It would be additional responsibility of FMS who are maintaining LAN/NICNET connectivity in the Bhawans under guidance and coordination of nicnet/network managers. Additional FMS are being proposed to be deployed at Bhawans under this project.
Q.12Type of reports which will be available on dashboard
Ans.Some of the sample reports can be viewed at and Attendance software is being developed with assistance of UIDAI team. Please send your valuable feedback in improving the features and MIS reports of the attendance system software.
Q.13Expected Role of NIC HoDs/Teams posted in Ministries/Departments
Ans.Deity/NIC/NICSI/UIDAI are the implementing agency for this project and the bio-metric attendance system will need to be made operational in every ministry/department as soon as attendance terminals are delivered which is expected soon.NIC HODs of the bhawan/ department/ministry or its attached/ subordinate office in consultation with nodal officer of that office will identify locations where attendance terminals are to be installed in the Bhawans.Since, NICNET connectivity is the primary connectivity for running the BAS. NIC Bhawan network coordinators are requested to help in getting the power supply extended at those locations with help of local CPWD offices. NIC Bhawan network coordinators along with network team at NIC hqrs will also be responsible for extending LAN/alternate connectivity at the entry gates and install WI-FI access points/Attendance terminals.NIC HODs posted in Ministries/Bhawans are requested to provide technical assistance to the Nodal officers in completing registration of all employees on the portal and provide handholding training/technical assistance in smooth installation/running of the attendance terminals. NIC HODs will also be keeping inventory of bio-metric terminals/devices installed in various locations in their Ministry/Department.
Q.14Role of nodal officers in the ministries
Ans.Nodal officers will get the details of all employees entered on the portal and also organize special camps in their Bhawans with help of UIDAI regional office, Delhi for enrollment of employees not having Aadhaar numbers.Nodal officers would also be responsible for creating masters of location, designation and divisions/groups within their organization.Verification of employees data will also be done by the nodal officers of the department whereas QC team of UIDAI will be assisting in verification of Aadhhar data of employees.You are welcome to send feedback and suggestions in helpdesk-attendance[at]nic[dot]in
