How the Scam Works:An acquaintance approaches you and offers to pay several hundred dollars (or more) if you will accept money for them through for your bank or credit union account. He or she may approach you in person or though social media. This person may also pose as a potential employer or lender who needs access to your account to deposit money. You give the scammer your bank account number, PIN and contact information. The next thing you know, you get a call or email from your bank. A check deposited into your account didn't clear, and your account is now overdrawn. It turns out the scammer used a mobile app from your bank to deposit fake checks into your account. Then, he/she withdrew the cash before the bank spotted the fake. This leaves you owing the bank however much the scammer took out. Tips to Avoid Fake Check Scams: Here are tips to avoid check scams: Know the consequences of bad credit: Taking cash in exchange for sharing your banking information (or getting a new smartphone contract) may sound tempting. But scammers will leave you owing thousands. These unpaid bills will be sent to a collections agency, and this could make it hard to get a loan, a job or even housing later.Confirm before you withdraw cash: A check can take several days to clear, and, until then, you are responsible for any funds withdrawn against it. To make sure the check cleared, call your bank.Be wary of checks received from unknown individuals: When selling to someone you don't know, it is safer to accept PayPal, cash or credit card payments.Do not accept overpayments: When selling on Craigslist.org or similar sites, don't take more than the sales price, no matter what convincing story the buyer tells you.Check your online bank statements frequently. Don't wait for monthly statements. If you see something you don't recognize, call your bank or credit union immediately.For More InformationRead more about check scams and banking apps on National Consumers League's Fraud.org.
