1) The best way to access your money in France is by using ATM’s. They’re easy to use, easy to find, and offer a better exchange rate than banks or money changing kiosks. Just make sure your pin is comprised of four digits and does not begin with a zero. Contact your bank or credit card company to ensure that the card will work in Europe and to confirm your daily withdrawal limit
2) Credit cards almost always provide the best exchange rate, though there is a foreign transaction fee, usually 1% – 3%.
3) American Express and Discover cards are not as widely accepted in Europe as they are in America, so if possible bring along another card, preferably a Visa or Mastercard, and always inform your credit card company of your travel plans.
