An Aadhaar volunteer's "fan moment" after he helped prepare MS Dhoni's card has become awkward for the government at a time it is confronting many questions about the biometric identification system. The agency for which the volunteer works has been blacklisted for 10 years after the cricketer's wife, Sakshi Dhoni, pointed out that his details had been leaked. In a series of tweets yesterday, Sakshi Dhoni drew Minister Ravi Shankar Prasad's attention to the fact that a tweet by the Common Service Centre - one of the many agencies involved in Aadhaar implementation - featured its volunteer with the former captain and also included a screenshot of his Aadhaar page, making his details public.
