Abhishek’s father, Amrith V. Chandy  of Chengalam near here,  said  that the child registered for Aadhaar twice. The first time was when he was a UKG  student of  St Mary‘s central school, Puthanangady.

“That time he didn’t mention it to us. The second was when we  registered for all the family members.” The three cards were of two numbers and in the case of one, the number was verified and found true. The other cards might have been sent by mistake, he said. This is  despite the Aadhaar authorities’ claim of taking  steps to prevent duplication.
