Credit Card Payment Info
Should you want to pay your membership, additional service and/or voluntary contribution using a credit card, please note the following:
According to European law, all credit card payment transactions must be processed using a strong customer authentication process called "3-D Secure" to increase safety for online credit card payments for both vendors as well as for customers.
Visa calls this procedure "Verified by Visa", MasterCard "MasterCard SecureCode", and American Express "Safekey".
If you face problems during the credit card payment process, please contact your bank or credit card company.
