@Mayur Banaskantha Sir , regarding your three queries.
For RBL Bank Account opening , you do the same yourself online through aadhaar card and mobile number linked with aadhaar card or if a branch is near to your home than you can visit the same and get the account opened.
Regarding your other two question below , unfortunately I have no idea as I have never done any linked FD or auto sweepin balance thing or related instruments.
I know a lot of people here use the facility of ICICI which offers this , but I am not having any knowledge on the product or if its possible with RBL Bank.
You may check directly with the nearest bank branch for accurate information.
Queries:
. (1) can we use linked fd/auto sweepin balance to apply ipo ?
(2) can we create linked fd/flexi fd/auto sweepin facility online using mobile banking/net banking ?
