Apple Overhauls MacBook Line Part 3: Touch ID Comes to macOS

Much has been made about the new Touch Bar on the MacBook Pro, but in many ways, the Touch ID feature may be more important, particularly to Apple. Hidden underneath the rightmost side of the Touch Bar is a fingerprint sensor. Unlike the explicit Home button based Touch ID reader in the iPhone and iPad, Apple has made good on embedding the sensor beneath glass. This could pave the way for a similar reader for iOS devices. After all, Apple now uses a non-physical Home "button" beneath the glass of the iPhone 7 and iPhone 7 Plus. If Apple can do the same for Touch ID, then the entire bottom of the iPhone could be part of the touchscreen, or the bezel could be shrunk or removed altogether.

The other advantages to including Touch ID in the MacBook is for password protection. Instead of having to remember dozens of passwords, or worse, using an easy-to-guess password for every site, users can now have complex passwords and rely on Touch ID to unlock access to websites. One of the features Apple really wants consumers to use is Apple Pay. Now that Touch ID is part of the MacBook Pro line, and Apple Pay is already web-enabled, Apple can provide a "closed loop" letting people securely log in to shopping sites and pay using their fingerprint, on a desktop or mobile device. In my opinion, Apple is on its way to becoming a bank. I think that may happen before Apple offers a car. And guess how you'll pay for that Apple Car? Apple Pay and Touch ID.
