They NET banking user interface is very bad. Very difficult to login and do transactions. Transaction history is also not shown correctly on screen.
More than this, Karnataka Bank does not show any courtsey to allow you to withdraw money in emergency in case you do not have check book. They do not allow to withdraw through withdrawal slip.
So be careful when you want to open account in Karnataka Bank.
