I'm so glad you caught it in time. My credit card has twice been used fraudulently within the past year. I have had to cancel my card and have a new one issued.

I check my credit card online every other day or so to make sure nothing unapproved has been charged.

The 2 times it's been used without my knowledge (I had the card in my possession) was after I bought books and magazines at the airport. I only use cash at the airport from now on.
