Many of us have been victimized in some form with credit fraud, especially if you shopped at Target or one of the other companies involved in the December 2013 credit card fraud. Even if you don’t lose money, it is very inconvenient to obtain new credit cards. Plus, the identity theft will have access to your personal information. They can use this to open new accounts in your name and easily damage your credit score.
