In 2024 having a card reader is indeed not that great, but I still have the one given by my bank ~20 years ago, as it's a strong factor which I can use to set up weaker second factors (typically push notification to the mobile app, nowadays).
We could imagine several ways people link their real, physical government ID to a trusted device. Every smart phone has had a built-in security key for the past 5 years or so. Banks have to check your ID at some point due to KYC. We could kill multiple birds with one stone.
