Barely making Rs. 2,000 a month as a domestic help, Urmila Yadav of Kanpur was in for the shock of her life as she found out last week that she suddenly had more than Rs. 9.57 lakh crore in her account. From a humble beneficiary of the Central government's Jan Dhan Yojana, Ms Yadav's bank balance had streaked past the net worth of Bill Gates - currently considered the world's richest person. On further investigation, it was found that behind the error was a server malfunction at the State Bank of India.
