I like the idea but my preference would be a hybrid of this.
- Go to the post office, have ID verified, papers verified, pictures taken, GPG keys created multiple so you can revoke one and leap-frog to another without being in an orphaned state, ID card printed that has a GPG signed PDF417 [1] code on both sides and a color picture.
- Lost card? Go back to post office and have them revoke your card and your active GPG key. Get new card that uses one of your unused GPG public keys that have already been uploaded to the various government servers.
- No RFID, no NFC, no Magstrip, no eco-friendly plastic. Make this thing nearly indestructible and only the PDF417 is used by sensors and can be scanned or photographed by someone paying their taxes or filing other government forms.
- Braille dots along top of card to make it easy to find the card and to show which way to hold and insert card in readers that should also have corresponding braille dots.
