Bengaluru resident Shashidhar Rao went to an Airtel store last month to get his Aadhaar number linked to his mobile connection. He had received repeated reminders from the telecom operator, which, along with other carriers, have been warning users to re-verify their connections by linking them to their 12-digit unique identity numbers to avoid discontinuation of services.
But when Rao placed his fingerprints on the reader, they showed up as invalid. “I tried a thousand times, with every single finger,” said Rao. Nothing worked.
