To ensure a safe shopping experience, we have implemented the personal authentication service "3D Secure 2.0." You may be required to enter a password or a one-time password during the process. If a notification like this appears during payment, or if payment fails, it may be due to one of the following reasons: - Your credit card is not compatible with 3D Secure 2.0. - Your credit card is compatible with 3D Secure 2.0, but pre-registration has not been completed on the card issuer's website. If the issue persists even after trying the above steps, we kindly ask you to contact your card issuer for further assistance and to resolve the payment issue.
