With Apple’s $356 million purchase of mobile security firm AuthenTec, for its nearly 200 patents covering fingerprint and sensor technologies, there has been a lot of talk about how Apple might integrate the technology into future devices. Adding to the rumors are recent reports that Apple signed a deal with Sydney, Australia-based Microlatch to develop NFC apps using its fingerprint authentication tech. Today, we get a look at some possible areas Apple might be exploring with the technology thanks to a patent application published by the U.S. Patent and Trademark Office and detailed by Patently Apple.

As highlighted in the image above, Apple’s patent covers a hidden color-matched or transparent “window”—next to the iPhone’s home button in this case—that could reveal “components by causing the electronic window to change opacity, allowing the components to suddenly appear as from out of nowhere.” In other words, Apple could build a biometric sensor or camera into a device’s bezel but have it remain invisible to the user—at least when not in use. One embodiment of the invention described using fingerprint tech during the unlocking process (pictured right):

The patent also covers similar methods using face recognition and eye recognition rather than fingerprint sensors; the invention would also not be limited to unlocking devices. The patent continued by describing e-commerce and wallet applications, which would line up with the earlier reports regarding Microlatch:

  • SEC filing sheds light on Apple’s AuthenTec purchase, fingerprint readers likely coming to iOS devices soon (9to5mac.com)
  • Does the latest iPhone parts leak suggest front-facing NFC hardware? (9to5mac.com)
