Nandan Nilekani, the Chief architect of Aadhaar, has said that the data of people is safe and it sits with the respective service providers.

"Aadhar is just an authentication process. When a bank uses Aadhar, it just authenticates and there is no transfer of data. Your banking information will continue to be with the bank," Nilekani said.

He was here to deliver a lecture on transforming governance through technology at the Centre for Organization Development here on Friday.
