How can I protect myself from the Target breach?

Episode 1041 (33:28)

Greg from Canoga Park, CA

Greg was one of the victims of the Target credit card compromise. Leo says he wants to know how he found out. He said he found a bunch of small charges on his Target Debit Card. Leo says he uses American Express and he gets a "physical card not used" alert every time an online purchase is made. That's a nice feature of AmEx. Leo says that if we as consumers start calling our banks asking for increased security measures, they may start implementing that more. Chase bank will send an email or text whenever the credit card is used, according to the chatroom. Bank of the West says they'll call for any unusual activity. But it seems like banks could do a better job of protecting against these sorts of attacks.
