When Apple released the iPhone X last year, the company made it a point to highlight the notion that the device’s Face ID is a superior security feature than the beloved Touch ID that debuted on the iPhone 5S. If recent patents are any indication, however, it might only be a matter of time before Apple reintroduces Touch ID to its lineup of devices.
The feature outlined in the patent, which was spotted by Patently Apple, would likely not make it to the 2018 iPhones, but the feature itself might not take years to implement either. This is because the tech outlined in the document, which is designated with a patent application number 20180225498, is already available in the market. Quite interestingly, the patent was also filed by Apple engineer Dale Setlak, who used to work for Authentec, a company that the Cupertino-based tech giant that bought back in 2012 to acquire technology that eventually got released as Touch ID.
