I hope Kotak Mahindra bank is the best Private bank in India. Which is providing 6% interest rate on saving accounts.Which is the best interest rate providing compare to all private banks of india and they providing more services, which will add the beneficiary to the customer. All banks providing ATM cards which has only 4 digit pin but only bank kotak bank providing 6 digits pin. Which is one of the best security feature.I will recommend kotak bank.
