You have to link your aadhar card with your bank account before April 30, 2017. Watch this video for complete details.
Bank customers must link their aadhar number with account before the end of this month. Otherwise your bank accounts will be blocked and no transactions will be allowed. Customers who opened bank accounts between July, 2014 and August, 2015 must submit aadhar as KYC document to avoid blocking of the account. In case if you don’t submit KYC document, then you will be not allowed to withdraw cash your account. Once you submitted the KYC documents, then your account will be reactivated again.
