According to a MoneyRates.com survey of 81 traditional banks and 36 online banks in June, online savings accounts can offer rates as much as five times higher than those at traditional brick-and-mortar banks.

(But keep in mind that in these days of rock-bottom interest rates, you'll hardly reap a fortune online. Five times a 0.1 percent rate on a savings account is still only 0.5 percent.)

Make sure any online bank you choose is FDIC-insured. Look for the FDIC logo on the bank's website or go to the FDIC's site and check the institution's status.

When banking online, it pays to be extra vigilant about security. When you finish a transaction like paying a bill or transferring funds from a checking to a savings account, make sure you fully log out from the site and close your browser.

Also, don't click on any link in email that purports to be from your bank — the email could have been sent by scammers who placed identity-theft software in the link.

If you want to verify something about your account, go to the bank website by typing its address yourself into your browser. For other tips, go to this FDIC webpage.
