If you ignore the last 6 points about cameras and displays, then this is kinda what "Smartcards" are, I think?

In fact the Estonian Id-Card is one of these if I'm not mistaken

Just to clarify Estonian Id-Card most certainly implements the PIV applet while Yubikeys implement both PIV and the OpenPGP Card (the latter has a benefit of natively supporting ed25519: https://github.com/wiktor-k/age-plugin-openpgp-card).

The problem with smartcards is: I don't see what's on them.
