Bank Card Compromised!!

I got a call today from the bank.  They were light on the details but my card had been compromised, and someone might possibly have access to my account.  They had immeadiatly locked my account.  I had to go to the nearest branch as soon as possible to get a new card issued.
To be sure, nothing funny happened with my money, I logged in to my online account to check my transactions.  Everything looked in order, thank god.
I went accross the street to the CIBC branch and got my fresh new card right away.
They had a story on the news recently about this though.  Apparently people are hacking the card readers at places like McDonalds so that they record card numbers and pins, then they come back later and collect their data.  Maybe that’s what happened.
