Like we already mentioned in previous articles, the ultrasonic fingerprint scanner also works with wet fingers and works with materials other than glass. So expect other manufacturers to use the same technology for phones made from aluminium or plastic. And while the technology in use is made by Qualcomm, other companies will surely design their own ultrasonic fingerprint scanners, so this won’t be limited to phones with Qualcomm processors.

Will this herald the death of the home button? If that happens, there’s a chance phones in the near future won’t even possess any physical buttons.
