i was cheking zerodha portal . account opening amount(rs 500 around) can be made thru online.
i tried the option , it is mentionable that online payment is made thru payumoney(even the account opening amount) and more surpising is that when routed to the gate way it has option to pay with credit card and if paid thru net banking i saw when it entered the banking payment gateway id and password was copied there as in case of email :annoyed:
