Would that work though? Unless it checks your pulse every 30 minutes I don't see how that would make it better. Bots would use stolen IDs for that. It would only contain it at a smaller scale probably
There's definitely a price where it doesn't scale and that price is almost certainly lower than what people would be willing to pay once for themselves.
It would have to integrate with some kind of official government ID, so that there can be extremely serious criminal penalties for ID theft. But that's something for the next republic, because the current one's justice system is unlikely to be up to the task.
