The indiscretion that next-generation iPhones will include a Touch ID, or one, is back on track fingerprint scanner, ultrasound hidden under the display. This time to revive it is the financial section of the Taiwanese publication United Daily News, which adds some technical details on the supply chain: the companies involved in the project are Qualcomm (for the scanner itself), BOE (for OLED displays) and GIS (for the touch sensor of the display). The involvement of Qualcomm is the main clue that suggests an ultrasound technology, at the expense of the optical one, more widespread and cheaper but also less safe.
As we said, it is not the first time that a return of the Touch ID in a more advanced form than the traditional one is assumed – which is still current, in a certain sense, given that it continues to live in the brand new iPhone SE 2020. They already had spoken Ming-Chi Kuo and Bloomberg, among others, still in 2019, however it is true that in more recent times discussions about it have dried up. Even Mark Gurman, a Bloomberg journalist famous for his excellent contacts in Apple, said he didn't expect it in the iPhone 12.
In short, that Apple still cares about fingerprint authentication at this point is a certainty; it remains to be seen if and when we will see its realization. On the other detail anticipated by the source, or the support for 5G connectivity, however, the consensus is unanimous and already reported several times a bit by anyone.
