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.
