Apple patents another way to scan fingerprints without Touch ID sensor

Apple has been granted a patent for a new type of fingerprint reading technology that doesn’t require a dedicated scanning sensor. The patent was originally filed by LuxVue before that company was bought by Apple in 2014. The design uses a combination of micro-LED light and infrared diodes to detect a pattern, making it possible to scan a fingerprint without the use of the capacitive metal ring in Apple’s current Touch ID sensor. The improvement could allow Apple to finally get rid of the dedicated home button and increase the iPhone’s screen size while still allowing the device to be unlocked with a fingerprint. The technology could also lead to other new features for the iPhone’s display, such as the ability to partially dim the screen depending on the available light, or even to dim certain areas of the screen to tackle glare.
