Well, this certainly seems like a no-brainer for PayPal. The company just launched a Facebook app that lets you send money to anyone on your friends list, with the usual list of terms and conditions in tow. After logging into Facebook and authorizing the app, you'll be able to use PayPal to transfer funds to individuals that you're connected with (who also have PayPal accounts, of course), adding a layer of security to the notoriously fraud-laden online payment service.

Payments are free to send and receive, but only if they're funded using a bank account with both parties in the U.S. Want to use a credit or debit card instead? PayPal will collect 2.9 percent (either from the sender or recipient), with a 30-cent processing fee to boot. And if you're sending funds abroad, fees range from 0.5 to 3.9 percent, depending on a variety of factors. A rather comprehensive collection of e-cards helps soften the blow if a fee applies, and includes selections for just about every occasion. Fourth of July coming up? Let's top up that fireworks fund. So dig up those account and routing numbers and get ready to stick some virtual cash in a virtual card -- just one week 'til Thanksgiving!
