How to Avoid Fingerprint Scams


It’s great when an app allows you to add extra security—a fingerprint scan or a depth map of your face, for example—to access its contents. In case someone ever gets their hands on your unlocked device (or figures out your PIN), it’ll be trickier for them to access critical apps, like your banking apps, if they don’t have your finger or face nearby.
What’s not so great is when scammy apps attempt to use your device’s security features to rip you off. And that’s exactly what’s been happening in some iOS apps lately, as Engadget recently reported. (Android, too, we presume, since no platform is immune to those looking to make a quick buck by taking advantage of gullible users.)

How the fingerprint-scanning scam works

Let’s take a look at the “Fitness Balance” app for iOS, which has since been pulled from the App Store. The app would pop up a screen that asks you to “scan your fingerprint to view personal calories tracker and diet.” A little countdown timer would start, too, for no reason whatsoever.
