Nandan Nilekani, co-founder of Infosys and the Congress' candidate from the Bangalore South constituency, seems to be leveraging his expertise as head of the Unique Identification Authority of India or Aadhaar project to prepare for the next general elections. To this end, he has been sending out personalised letters to the heads of every household within the constituency. What is unusual is that the cover containing the letter looks nearly the same as those that were used to send out the Aadhaar numbers and bears the name of the addressee and his/her father on it.
