The same way you verify that the person using the banking app is the one they are supposed to be. Or any other service.

Obviously you use your device, and you can lock it with a password. You can use two factor authentication.

It's straightforward, really. You sound like identity has never been solved electronically.

If anything, holding a physical paper id document is far less secure than a personal device with your private keys in the Secure Enclave.

It's not been solved though, at least here in the UK where people are against mandatory ID cards.

That's a separate issue. Why would you want to allow voting without any ID?

It's definitely not a separate issue, it's fundementally linked. Voter registration is separate and not tied to any electronic ID, so you saying it's a solved problem isn't true.
