The following steps will help you to mail (via secured channel) your registration fee.
1. the ISC account is in the USA and receives payments only in US dollars. Hence, the membership fee in euros that you committed to pay when you registered as an ISC member, must be converted to US dollars before you pay using your credit card. For a quick and precise currency conversion you can use the OANDA website (www.oanda.com/convert/classic).
2. Eligible credit cards are Diner's Club, Visa, Mastercard, Discover. Sorry, we cannot accept other cards.
3. If you use Visa, Mastercard, or Discover, you will be asked to
supply your card verification number (last 3 digits of the number printed on the back of the card)
4. Write the sum (currency: US dollars) as XX.xx or X.xx.
