3D Secure

About unauthorized use and chargeback

Unauthorized use refers to the use of a credit card by a person who pretended to be the card holder. Once the unauthorized use is revealed, the credit card company initiates the chargeback*.

*Chargeback is the denial of payment proceeds by the credit card company to the merchant, when the card holder disagrees with the payment due to fraudulent activity.

When chargeback occurs, proceeds of such transactions cannot be paid. In addition, if the clearance has already been completed by GMO-PG and the merchant, and the payment cannot be offset from the recent transfer, the merchant has to pay the amount back to GMO-PG. Therefore, the proceeds might not be paid to merchants, even if they have already delivered the goods or have started providing the service.

Why is it important?

3D Secure is very effective as a security measure to prevent increasing incidents of unauthorized use of credit cards and credit card forgery, because it requires inputting the password known only by the card holder.
