Police departments across the country are warning of the sneaky new Venmo scam that can drain your bank account in seconds. Most people who use the tool — and others like it — are linking it to their debit card which can put them at risk, especially if they’re too trusting. The apps make it easier to send cash, but as the popularity grows, so do the scams. It works like this: Someone asks for your phone, saying their battery died or they left theirs at home. Next, they’ll say the person didn’t pick up, and they need to text. While you think they’re texting, they’ve actually gone into your payment app to transfer funds out of your account into theirs.
