Bro, just got aadhaar fingerprint auth rejected two days in a row. Don't think i'll get it to work anytime soon. Local states' aadhaar auth rejection seems to be 30% rejection rate. (For first 3 months of 2017).
Those changes have little to do with Aadhaar. Efficiency in delivery could be achieved despite Aadhaar. If you look at the savings figures and all the analysis put in by many people, you'd understand that the government is publishing bogus figures. In the case of cooking gas (LPG), even the CAG (Comptroller and Auditor General of India) disproved the claims of huge savings.
