As people wonder when they can see the exit of the corona, there is controversy overseas about the pandemic specification that is said to be adopted in the iPhone 13 series released in 2021. Most experts think that Touch ID will be installed in addition to Face ID, but it is still unclear what technology will be used and which will be installed in the model.
The sensor is either optical, optical / capacitive hybrid, or ultrasonic.
MacRumors reports on the in-display fingerprint sensor used by Apple’s iPhone 13 (reference:https://www.macrumors.com/2021/01/29/iphone-13-in-display-fingerprint-sensor-optical/）。
Apple is working on the iPhone 13’s in-display fingerprint technology, and a second biometric can be used in conjunction with Face ID, The Wall Street Journal reports. Bloomberg also makes similar predictions.
It is likely that an optical sensor that uses 2D images will be used to read the fingerprint. Ultrasonic fingerprint sensors, on the other hand, are a new technology that creates 3D maps of fingerprints that work well with wet fingers, but are much more expensive.
The Touch ID home button that Apple has adopted for iPhones, iPads, and Macs uses a capacitive sensor. There are also optical / capacitive hybrid sensors. It combines high-speed scanning of optical sensors with security of capacitive sensors to improve performance. It’s very unlikely that Apple will use the unsafe standard optical sensors used by some Android devices.
Meanwhile, Minchey Kuo, a prominent analyst at TF International Securities, believes Apple will use ultrasonic technology. GIS will provide ultrasound technology to Apple, and Qualcomm will provide ultrasound modules and lamination. Apple has also patented the related Touch ID feature.
If a costly ultrasound solution is adopted, it is unknown whether all iPhone models in 2021 will implement it.
