Life can seem pretty predictable until one day your checks bounce, your credit cards are declined, or you're turned down for a loan. You're left wondering what happened. It only takes a second for a thief to grab your wallet or an internet "phisher" to snatch your credit card number online, but it will wreak havoc on your life for a long time to come. Make sure you know how to protect yourself before it happens and the steps to take if it happens to you.
