Perche - what you need is a Chip 'n Pin card and you have Chip 'n Signature as has been pointed out above. One way is to get a US Chip 'n Pin card but there are not many US cards that provide it. If you can get an Italian credit card, that would have Chip 'n Pin. Finally, it has been reported that some Chip 'n Signature cards (which you have) do work in machines with a 0000 pin. It may be a long shot but you might try to pay with your card and enter 0000 to see if it will work.
