If you entered a wrong Netsecure code, the screen would prompt “Invalid OTP”. Such an error may occur when you enter a Netsecure Code that has already expired. Customers must record each Netsecure Code that holds a validity of 90 seconds. In case you receive any error message, click the “On-Call OTP” tab” to get a new Netsecure through an automated voice call. Use a new OTP to complete your transaction. If you type an incorrect OTP 5 consecutive times, your ID would be suspended for 24 hours, and you will not be allowed to make a transaction.
