The linked bank accounts are simply the bank accounts that you have added to your Kotak Securities Neo trading account to deposit funds into. You can transfer funds from either of these bank accounts, which are linked to your beneficiary account. There is no limit to the number of bank accounts that can be linked to Neo, but only 10 can be linked to your beneficiary account. Under the "linked bank accounts" section of the IMPS/NEFT/RTGS payment option, you can see a list of bank accounts that are linked to your beneficiary account.
