text: Man tries to use stolen credit card... then caught using own rewards card - StarTribune.com
  The story, though, doesn't end there.
  Store employees contacted police to tell them about the attempted use of a stolen card. They also told police about the motel. Here is the head-scratching part: Police were able to track down what hotel room the man and woman were staying in by matching the name from a rewards card he used with a name registered to the motel.
  That's right. Police found the man in his motel room because he used his actual rewards card to earn points for a purchase he first attempted with a stolen credit card.
  The 34-year-old was booked into to the Ramsey County Jail for felony unauthorized use of a credit card.
