A credit card fraud question: I recently had some purchases made with my debit card number in Los Angeles and Massachusetts within a few days of each other (I'm in the Upper Midwest). I still have the card in question, yet both of these purchases were Point-of-Sale, and they weren't mail-order. Did credit card thieves somehow encode my number onto multiple fake plastic cards? What's going on here? [more inside]
