ID has traditionally had a copy of what you look like embedded into the surface, but wouldn’t it be nice to have an ID that encoded what you sound like? If certain characteristics of my voice could be narrowed down to a QR code I’d feel a lot more comfortable identifying myself with a mic instead of a camera. You could combine that with only one side of the ID showing the QR code and a some proof of age and keeping my actual name to the other side, hidden from the camera. Have me say a random number, see if it matches the QR code for “en_US, male, tenor, southern French accent” to prove it’s me, here, and alive?
