Which is better: DDPI or e-DIS OTP-based authentication?

Both DDPI (Demat Debit and Pledge Instruction) and e-DIS (electronic Delivery Instruction Slip) OTP-based authentication serve the purpose of authorizing securities transactions, but they work in different ways.

• DDPI provides pre-authorization for specific actions, removing the need for OTP verification for each transaction. This makes trade settlements and pledging processes faster.
• e-DIS requires OTP verification for each transaction, providing enhanced security through manual approval of every action.
