What is liability shift?

If you have 3D secure (3DS) authentication enabled, you are no longer liable for certain fraudulent chargebacks when a cardholder denies they made the purchase. MasterCard SecureCode, Verified by Visa, American Express SafeKey and JCB J/Secure are all 3DS cardholder authentication schemes which help the card issuer authenticate the identity of their cardholder when making an online purchase. If authentication is completed, any liability for any subsequent fraud-related chargeback on that transaction shifts from you to the card issuer.

Cardholder authentication schemes are applicable to Internet transactions only and do not cover MOTO orders or recurring payments as the customer can't enter their authentication details.

When will I be covered?
