Bankrate reminds us that online payday loans may well be scam that extracts your personal information.

For starters, you'll provide an amazing amount of personal data -- Social Security number, driver's license number, mother's maiden name and, of course, your name, address and employment information -- to the Web site.

You'll also give your checking account number and bank routing number, so the lender will have access to your account. The lender will deposit your loan into your checking account and dip into your account to extract interest, fees and the principal. Some require that you fax them your latest pay stub, most recent bank statement, photo ID and a voided check.

But to whom are you giving this information? More than likely you won't have a clue. Many Web sites that pop up when you do a search for something such as "payday loans" aren't lenders at all. Take Advance Cash Loans, which states at the bottom of its home page, "Advance Cash Loans is not an online provider of online payday cash advances. We simply connect people seeking fast cash advances with online providers of instant cash advances so they can get the advance cash that they need, as soon as possible."

A Consumer Federation of America (CFA) survey, of 100 online payday lenders and referrals sites, found that many are run from outside the United States and, perhaps, out of reach of American laws.

"You don't know where your information is going," says Jean Ann Fox, director of consumer protection at CFA.
