Wow I was wondering why Chase randomly sent me a warning and a new debit card a few weeks ago. I had made no unique purchases aside from coffee and books from Barnes and Noble and initially thought the new card from Chase was a fake. At stores like the one at NY's Union Square, the cashiers never leave their stations from 10am to 10pm. I wonder how this could have been done so quickly as to not cause suspicion. Perhaps there might have been some internal cooperation?
