In theory it is possible to use a US issued credit card in Europe. In practice, forget it unless you are willing to face the embarrassment of 50% of places declining your card. My experience in the UK is that outside London you are very likely to find that the only cards they accept are chip and pin cards. Now according to the VIsa and Mastercard agreements, this should not be the case. Only the UK banks could not care less what Visa and Mastercard want, they have zero intention of enforcing the requirement on merchants. They are fed up with the fact that the US banks refusal to deploy chip and pin means that they still face serious fraud losses C&P has eliminated for card present transactions in the UK. The attack presented by Ross Anderson is interesting, but fixable. The hard part was insisting that everyone would use chips. As with SSL 2.0, the protocol has holes. They will be fixed. Meanwhile US cards have no security at all. I have a UK card just so I can spend money in the UK. _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
