Hotmail's Co-founder Sabeer Bhatia said that spending $1.3 billion on building Aadhaar was unnecessary. He said, "Aadhaar is like $1.3 billion ill spent...Because Aadhaar took all of your biometrics, where is that being used?...You can build it in under $20 million." "Whoever did this is not a technologist...They don't know technology. They have never coded in their lives," he added.
