All wonderful questions, and maybe some of the tech needs to be refined. But I can already cryptographically sign transactions on my hardware Bitcoin wallet. Embedding displays into cards isn't impossible, BofA does it for OTPs already. A combination could ensure that users know the vote they're casting by confirming it on a secure hardware token. With that done, you could upload that vote to a blockchain based system that's auditable, but anonymized. But I can't give you a good answer to "what if someone steals the phone and card". One solution is to have remote election officers that verify your identity via the camera in real-time as you cast the vote. They could look at your face, or even read your fingerprint off the camera (I know that's possible because my country lets banks do that). You'd only be able to cast the vote through devices with good enough cameras and under good enough lightening and you may have to wait a little while, but it'll be secure and you won't have to travel — especially if you're registered in a distant state or district. It's better than nothing.
