For conference registrations, we can now charge credit cards in other common currencies, namely Australian Dollars, Canadian Dollars, Japanese Yen, British Pounds and Euros. The FAQ item has more details. For those currencies, this avoids that residents of Australia, Canada, Japan, Great Britain and the Euro countries see a different amount than the nominal registration amount on their credit card statement. Unfortunately, our credit card processor only accepts these currencies for Mastercard and Visa.
Due to the limitations of our credit card processor, we can only transfer the amount to the conference after conversion to US Dollars or, for smaller conferences, Euros.
