Can you use any U.S. gift card anywhere in the world to pay at a counter with a VISA logo?
I read on some web sites that U.S. gift cards don't work in Europe, but no reason was given, others were talking about 7% fees.
Does the VISA logo not guarantee that a payment will work? What exactly happens behind the scenes when the card is swiped? The credit card data and purchase sum gets transmitted to the issuing bank (routed through some central VISA system to identify the right bank by the card number?), the balance gets checked, and reduced, and then the cash desk gets confirmation that everything went smooth?
How can this process be blocked for certain shop & issuer combinations? Or is there some law in Europe not allowing anonymous credit cards, and the VISA or bank server tells the cash desk that this card is not usable?
Are conversion fees bank-dependent?
