That Fingerprint Sensor on Your Phone Is Not as Safe as You Think
Fingerprint sensors have turned modern smartphones into miracles of convenience. A touch of a finger unlocks the phone — no password required. With services like Apple Pay or Android Pay, a fingerprint can buy a bag of groceries, a new laptop or even a $1 million vintage Aston Martin. And pressing a finger inside a banking app allows a user to pay bills or transfer thousands of dollars. While such wizardry is convenient, it has also left a gaping security hole.
