Small note but I wanted to say just having returned from 3 weeks in northern Italy that tapping credit cards has become the norm - especially in restaurants and smaller stores.
I have two credit cards without foreign transaction fees and I planned on using one more than the other, but since it didn't have tap capability I only used it for large charges like hotel rooms because of the hassle of chip and signature. It's very fast and finally removes the hassle and stigma of American credit cards - no swipe, no explaining we don't have PINs etc.
Just FYI,
