Payment Procedure

After you complete your registration, please click the "Go to Payment Page" button.
Payments by credit card will be accepted.

[How to pay by credit card]

The credit cards listed below can be used to make payments.
Visa, MasterCard®, JCB, AMEX, Diners Club

*Your credit card statement will show that the payment has been made to the name of JTB Corp., which is the agent handling registration.

1. For VISA, MasterCard®, and JCB cardholders

This system supports 3-D Secure for certain cardholders in order to provide a more secure online payment experience.

What is 3-D Secure?

This system adds an authentication step to the online payment process by requiring the user to enter a previously registered password on an authentication screen provided by the credit card issuer. International credit card brands VISA, MasterCard®, and JCB recommend that merchants make use of this system.

Credit card issuers use different names to refer to their implementation of 3-D Secure, including Verified by VISA (used by VISA), MasterCard® SecureCode™ (MasterCard®), and J/Secure™ (JCB).

*Some issuers allow cardholders to use the same password they have been assigned for accessing their monthly statements online or having them sent by email. If this password is not entered, or if an incorrect password is entered, the online transaction will not be completed.

*If you forget your password or experience other authentication-related issues, please contact your credit card issuer. (For more information, see your credit card issuer's website.)

*In terms of the actual payment process, once you have entered your card information (issuer, card number, expiration date, and cardholder name), click the "Next" button to proceed to the credit card issuer's authentication screen.


*If the authentication screen is not displayed, please confirm card number and expiration date, and take a procedure again. Or close your browser window, log onto the AMARYS registration screen again from the event website (scientific society conference, etc.), and enter another credit card on the payment page. Alternately, you may wish to contact your JTB representative.

*If you cancel the authentication process on this screen, your online transaction will not be completed. (Avoid using your browser's "Back" button.) Also, canceling the authentication process will prevent you from returning to the current application screen, so you'll need to log onto the application top page again and repeat the payment process.

2. For AMERICAN EXPRESS(AMEX) and Diners Club International cardholders

Card number, expiration date and security code will be required for the payment.

*The security code is the last 3 digits of the number printed above the card holder signature area on the back of the card.

*For American Express cards, this is the 4 digits number stamped above the card number on the front of the card.

For more details on the credit card payment, please refer to *About Payment* on My Page.


Your registration will be completed upon receipt of your on-line registration information and payment. Please print out your confirmation slip by clicking the "Confirmation sheet" button and bring it with you to the On-site Registration Desk.
