I used my chip card in Canada during the last week. I used my visa chip card heavily for gas, bc ferries, food, etc. I remember giving out my card number, expiry date and security code to an agency that offers whale seeing tours in Victoria Island. Next day, I saw two charges: $108.XX from Chick-A-Fil, Salisbury, MD and $1.00 from Sweden. The card issuer called me right away to verify what's going on.

I wonder how my cc details were compromised. Was it a skimmer at gas stations? or one of those credit card scanners in Canada (Canadians seems to use PIN number with credit cards) or bcferries.com website.

I am not sure.
