Thumbprint, heartbeat, even posterior 'readers' emerge alongside the popular iPhone 5S.
While Apple fans have long awaited this big update, so has another group: the biometrics industry. Sensor companies have been wishing for a major player to swoop in, show how far the technology has advanced, and persuade shoppers that biometrics can be cool.
"Many think that the iPhone 5S is a tipping point for consumers," says Adam Vrankulj, editor of the industry news outlet Biometric Update. After Apple purchased fingerprint-sensor company AuthenTec for $350 million in 2012, the stock price of several similar firms more than doubled.
Fingerprint sensors have come a long way since 2002, when researchers found a way to trick high-end scanners with fake gelatin fingers. Today's technology not only reads the tiny ridge patterns, but some can also look at blood flow and vein patterns underneath the skin.
