American Express International Currency Cards are not representative of the requirements for obtaining a bank-issued European credit card, which require evidence of residency.

If your income is earned in dollars an International Dollar Card will not help you avoid foreign transaction fees, in fact the IDC charges more to convert to dollars than do USA issued American Express cards. An International Euro Currency Card will help avoid fees on transactions denominated in Euros (but not Pounds), provided you have a way to pay the bill in Euros.
