They confirmed that optical Touch ID is coming. The iPhone 13 can then be unlocked in several ways: with Face ID for the face and Touch ID for the fingertips. Apple is said to be testing Touch ID under the screen for the next generation of iPhones. These will be in the shops from September 2021, if everything goes according to plan. A former employee who previously worked on Touch ID told The Wall Street Journal that leaps and bounds have been made with an optical scanner. The current Touch ID buttons work with a capacitive sensor.
Apple would have said that the optical fingerprint scanners will only be used if it is as secure as the current Touch ID. The finger scanner is still used in the current iPhone SE and most iPads and MacBooks. Apple recently processed the sensor in a completely new place: in the power button of the iPad Air 4.
Ultrasone vs optical scanners
Ultrasonic scanners use more modern technology and are more reliable, but also more expensive to produce. The advantage is that they work under many conditions, even with wet fingers. They map the 3D structure of a finger and are therefore more difficult to fool than scanners that make an optical image of the pattern.
Some Android devices use optical scanners, which are easy to get around. Apple could opt for a more advanced hybrid sensor, which combines optical and capacitive properties. This can make it just as safe as current scanners.
Rumors about Touch ID were already in the screen with the iPhone 8.
‘Galaxy S21 contains hints’
The revelation can be found in an article by tech journalist Joanna Stern, who describes how she can unlock her device in half a second with the Samsung Galaxy S21 when she wears a mouth mask. With the iPhone, it takes three seconds, because Face ID first tries to take action and then she still has to enter her pin code. Stern then says that Apple is working with fingerprint scanners in the screen. She heard that from a former employee. According to Stern, we can find hints in the Galaxy S21 for innovations in the iPhone 13.
The iPhone 13 may also be called iPhone 12S, as no major changes are expected. However, Apple could apply a 120 Hz screen and a smaller notch. Another possible improvement is that there will be a time-of-flight camera in all models.
By the way, analyst Ming-Chi Kuo thinks Apple will opt for ultrasonic technology, provided by the company GIS. Qualcomm supplies the ultrasonic module and the lamination. We are curious who will be proved right.
