The most important benefit of SPEED-e is the convenience of submitting delivery instructions. You can access the SPEED-e website from anywhere in the world at any point of time, check balances in your account, submit the instructions and track its status. SPEED-e eliminates the requirement of having to give the delivery instructions in paper form. Further, if you are a smart card user, you get an added benefit of freezing account(s) / ISIN(s) and / or specific quantity of securities under an ISIN through SPEED-e, which cannot be unfrozen even by your DP.
