Fraudsters are using payment apps such as Paypal and Zelle to trick you out of your money. Getty Images By Rivan V. Stinson, Associate Online Editor April 4, 2018From Kiplinger's Personal Finance Finding a good hairstylist is hard, but finding a traveling hairstylist is even harder. As a splurge, I looked for someone who would come to my apartment to spend four or more hours braiding my hair. Thanks to social media, I succeeded.See Also: Best Banks for Millennials My text exchanges with the stylist went smoothly. I described what I wanted, and she told me to send a nonrefundable $150 deposit–half of the cost–via PayPal's peer-to peer (P2P) payment function. The alarm bells didn't go off until I couldn't reach her on the day of the appointment. Was this stranger going to show up as promised, or did I just lose $150? Sponsored Content Fortunately, she did show up that day. I hadn't been able to reach her because her cell phone battery had died. In hindsight, I realized she could have catfished me–created an elaborate fake profile and passed off someone else's work as her own–and then not shown up. I would have been scammed, with no recourse from PayPal. Growth of P2P. Members of my generation are big users of P2P apps, such as Cash, PayPal, Venmo and Zelle. The apps are fast, and often all it takes to transfer money to another's bank account is an e-mail address or phone number. In fact, 62% of millennials used these apps to send or receive money in 2017, reports Bank of America. Advertisement But as the use of P2P apps grows, so do complaints about scams. The Federal Trade Commission added online payment systems to its complaint database last year, and I've noticed more scam complaints posted on social media sites. The schemes are similar: Someone pretends to be selling, say, concert tickets, dupes victims into sending money and then disappears. As consumers, we have come to expect some form of protection when we link our bank accounts or debit cards to these apps. But when you're using electronic forms of payment to make a purchase from another individual–instead of a traditional merchant–the rules are different and there's less protection against fraud, says Sarah Grotta, of Mercator Advisory Group. If anyone ever took the time to read the fine print, they'd know this. For instance, according to PayPal's purchase protection guidelines, when you send money through its friends-and-family P2P system, you're not covered for any losses because you authorized the transaction. If someone hacks into your PayPal account to make an unauthorized transaction, however, you're protected. Venmo, owned by PayPal, states in its user agreement that personal accounts are meant to be used only between family and friends. Its definition of what's considered an unauthorized transaction is similar to PayPal's. The same goes for Cash. Zelle, another P2P app, looks like a safer bet because it's backed by big banks, such as Chase, Citi and Wells Fargo. But banks that have integrated Zelle into their systems stress that the app is for sending money to someone you know. If you do business with strangers and get scammed, you're likely out of luck. Advertisement Grotta's advice is never to send money to people you don't know. If you've been hacked and money has been transferred from your account without your consent, contact your bank and the P2P service by e-mail or phone as soon as possible. The P2P service will investigate your claim and determine if a full refund is due. Ultimately, treat your P2P payments as you would cash. If you wouldn't feel comfortable giving a stranger cash before receiving a product or service, don't send that person money by Venmo, either. Once the money is gone, it's gone. I'll be sure not to take the flight risk with my money again. See Also: Credit, Debit or Cash?
