Probably has absolutely nothing to do with this but I got notified yesterday that my credit card was hacked. I got the usual "hacked" notice on my NOOK reader (android based) a few weeks ago when I came to CC and closed it out and haven't gone back since. Probably a coincidence but NOOK keeps my credit card # on the Barnes & Noble site for books I purchase.
Fortunately Capital One was on it like a duck on a june bug and shut down my card within an hour of so. Probably just a coincidence but when I asked the fraud agent what are the most likely way this could have happened - gas pump or ATM she said - I hadn't used my card for any of that. That pretty much left an on-line transaction or someone scanned it in my wallet even though I use shields to keep my cards in.
So - never know.
