Interesting take on having an iPhone with Face ID, Touch ID, and Voice ID. David Farrington:
Phones already have decent microphones and voice recognition technology has been around for decades so this should be a no-brainer, technology-wise. Consider this a trifecta. Voice recognition, fingerprint recognition, and facial recognition. The most convenience would be to have any of the three options to open an iPhone, or, two of three, or, all three. You choose. And, of course the venerable password.
