I can assure you that this will not be feasible on a national scale in our lifetime and it very much is the technology that is the problem. “Work like a credit card” implies not tamper-proof enough for an election.
This experiment was done with a ‘hack proof’ voting system based on existing tech before. It remained unhacked for about 4 hours.
You might be able to do it with a system that exploits quantum mechanics to distribute keys and detect intrusion on communications, but this tech is not widely available outside of physics labs in China and Austria.
