I have a call about card fraud at least twice a year. Sometimes it’s legit (attempted) fraud, and other times it was my own purchase they just found unusual. Happens to my US cards as often as my Taiwanese cards.
Sometimes the calls about card fraud are the actual fraud attempts. I don’t know if there’s any specific crime wave right now, but this seems to be a constant in the world we live in now.
Got an SMS yesterday from Citibank saying “To ensure the safety of your Credit Card, we would like to replace your card with a new one…”…and they requested me to call their Help Desk. So I called today and they said one of my cards has apparently been used in some suspicious transaction and they cancelled it…I hardly use that card except for a few online transactions once or twice a year and filling gas in the Self Service stations. Anyway, they agreed to send me a new card via registered post and I should receive it within a week.
