Safeguard Your Financial Life

2. Use a credit card with a small limit for mail-order and online purchases. It's all too easy for a dishonest sales clerk to use your credit card information. If the card you use for these purchases has a low credit limit, at least thieves won't be able to rack up many bills before hitting a wall.


3. Get it in writing . Require anyone who solicits you over the phone to first send their information by mail, so you can check its legitimacy. While you can curtail the number of phone solicitations you receive by placing your number on the National Do Not Call registry, it won't get rid of everybody. Certain organizations, like charities, political groups, telephone surveyors, and companies with whom you already do business, are still permitted to call.

4. Review your monthly statements . Like flossing your teeth, this is a simple thing you can do to ward off calamity, yet it's surprising how many folks neglect to do it. Not only will reviewing your monthly statements alert you to possible fraudulent charges, you may also find legitimate charges for services that are either redundant or no longer necessary. For example, a close friend of mine realized she had been paying for two AAA memberships, one under her maiden name and one under her married name — for four years! Lesson learned.

5. Prepare for disaster . With the recent anniversaries of Hurricane Katrina and Sept. 11 looming large in the American psyche, it's more important than ever to make sure you safeguard your family's important documents in case of a disaster.

6. Choose your PIN wisely . While you want to choose something you'll remember, you don't want it to be something that a clever thief could figure out just by learning your birth date or your child's name. A combination of uppercase and lowercase letters, numbers, and symbols will offer you more security.

7. Guard your Social Security number . Make sure that anyone asking for your Social Security number really needs it. Often businesses that ask for a Social Security number can use an alternative customer identification number if you ask. Make sure not to print your Social Security number on checks or in other highly visible places. For more information on protecting your Social Security number, check the Privacy Rights Clearinghouse.

8. Opt yourself out of all pre-approved credit card offers . If your mailbox is anything like ours, it's littered with pre-approved credit offers and cash-advance checks, all of which could spell disaster in the hands of the unscrupulous. Instead of tossing these in the garbage, call 888-567-8688 to eliminate them for up to five years. I was able to register my name and my husband's in a three-minute phone call.

9. Be vigilant while using the Internet . As the victim of a phishing scam myself, I can't stress this enough. All it takes is one lapse of judgment, and you may find your accounts drained and your credit tarnished. Independently verify the validity of any requests for personal information before you give out any of your sensitive data.

10. Protect your computer's security . Use as many tools as you can (anti-virus software, spyware, firewalls, and passwords) to guard your computer information from the nefarious. Failing to protect your computer is just as bad as leaving your door unlocked, your windows wide open, and a sign on the mat, saying, "Burglars, come on in."

No need to make the thieves' jobs any easier. Though they're not foolproof, these simple tips will help ensure that your financial data is a whole lot safer.
