Debit cards and prepaid cards are generally closed to Mail Order transactions.

So, can Non-3D (non-3D Secure) transactions be carried out online with debit cards?

Similar to the above, debit cards and prepaid cards are generally closed to Non-3D (non-3D Secure) transactions as well.

Why do banks impose this restriction?

Cardholder verification is weak in mail order and non-3D transactions. Because spending on debit cards directly affects the money in the account, the customer's loss becomes apparent much faster in the event of fraud. Banks start out with these transactions disabled in order to reduce this risk.

If a customer needs these transactions, they can make a request to their bank; if the bank approves, it may also define a limit and a time period.

The recommendation for merchants is to use 3D Secure whenever possible and to offer mail order only in scenarios where it is genuinely required.
