As a potential Mr. Doe, I'd love to have an ability to opt in to a stricter mode of banking. I would voluntarily ask my bank to refuse certain types of transactions in my name unless my identity can be confirmed by secure machine-readable means at my presence; internal phone calls should not qualify. It could be a bank card, or a passport — yes, both can be physically stolen, but it's much harder to pull off, and I would immediately warn my bank when I notice.
