Identity Authentication Service

Identity Authentication Service

The Identity Authentication Service makes credit card payment over the Internet more secure. 3-D Secure, part of the Identity Authentication Service, is a service that verifies an individual’s identify by having them enter a password registered with their card issuer in advance in addition to their card number, expiration date, and other details during payment. Since September 2021, we also provide EMV 3-D Secure, which uses one-time code and other methods to verify the identity only for those suspected of fraudulent use.


Prevents identity theft by unauthorized users

Damages caused by fraudulent credit card use are increasing in online transactions.
With the Identity Authentication Service, verification is done using a password or one-time code that only the cardholder could know, allowing you to prevent "spoofed" payments with stolen cards by unauthorized users.

We also offer other solutions to counter fraudulent use.

Reduces risk of chargebacks

When a credit card is used by a third party, the card company will refuse to pay the merchants for the sale (a chargeback).
In principle, card companies do not issue chargebacks for payments that have gone through personal authentication. (There are some exceptions and rules for each brand)

(EMV 3-D Secure) Only verifies those suspected of fraudulent use

EMV 3-D Secure analyzes multiple data points in real time to determine possible unauthorized use, including credit card usage history, the device used by the person making the card payment, as well as the delivery address for the product at the time of purchase. Authentication will only be performed on cardholders suspected of fraudulent use.
Cardholders not suspected of fraudulent use can save the trouble of verifying their identity, making for smoother transactions.
