A secondary bank account is another bank account that can be linked with 5Paisa. You can use a secondary bank account to add funds to your trading account. However, no withdrawal activities can be carried out using this secondary account. 

Note: Withdrawals can be made only through your primary bank account which you used at the time of creating your 5paisa account. 

It must be remembered that there can be multiple secondary bank accounts added to your 5Paisa account, but only one is considered to be primary.
