Last time it happened to me, card was used in Hong Kong, an IN PERSON, physical card swipe. I haven’t even had a passport for over 10 years.
Bank actually caught it, cancelled the transaction and the card. However, they didn’t tell ME. Found out in grocery store line, fortunately had cash.
They never told me where/how the card was compromised even though I wrote twice about it.
