My understanding is that, in the sane states like NY and CA, the vaccine info on the cards is also being entered into official databases (which already exist to record childhood immunisations). Insurers and hospital networks, as well as pharmacy and clinic injection sites, are also recording the jabs to reduce their own liability.
The sane states will eventually create apps and cards with QR codes that will match the vaccination record to a government-issued ID. NY is already developing its app. Federally recognized private passport issuers will provide similar services for sane residents of bonkers stars like like FLA who want to travel. There’s still potential for forgery, but a lot less than with the current paper cards.
The federal government won’t be doing this or mandating that all states do it, because America. There will also be lawsuits from anti-vaxxers against businesses (esp. airlines) that will require officialpasses/passports. But as long as this stupid country doesn’t reach herd immunity, these passes/passports are coming.
