iPhone 5S — Touch ID
Apple introduced Touch ID on the iPhone 5S, making fingerprint authentication mainstream and paving the way for biometric security on mobile devices.
On September 20, 2013, Apple released the iPhone 5S featuring Touch ID — a fingerprint recognition sensor built into the home button. For the first time, users could unlock their phone and authorize purchases with a fingerprint instead of a passcode. The sapphire-covered sensor could read fingerprints at any angle and improved with use. Touch ID made biometric authentication effortless for hundreds of millions of people, dramatically improving mobile security while reducing friction. It also introduced the 64-bit A7 chip — the first 64-bit processor in a smartphone — and the M7 motion coprocessor, establishing Apple's silicon advantage that would grow with each generation.
