With so many people losing wallets and physical, plastic pieces of ID cards, drivers licenses, etc., why haven't we moved on to fully digitized ID in the digital world? We have made money almost indefinitely digital -- at least non-physical (most people have banks, PayPal, or other forms of electronic payments in which carrying cash is unneeded); however, we're still lugging around plastic molds with pics on them.
If we digitized IDs, wouldn't that be better for the environment too? An ID could be verified by a government server or private sector/database digitally and you can use extensive security/encryption/password protection schemes to conceal a photo of you, your address, license number, etc.
When police stop you, just load up a walled-garden app on your smartphone, tablet, etc., and they'll be able to verify your ID, and check your records with it too; they won't be able to see anything else/do anything else on your device though. This is secure, stable, and way more efficient. If you lose your device, you never lose your ID though, because its information is always secure remotely.
If you don't have a digital device on you and can't be verified, a cop can provide one/access your records anyways by asking you a secret code or key to decrypt your records too. This should also make identity theft enter a whole different ballpark too, as nobody can find out your name/info/etc. as easily.
The same measures can apply for all other plastic cards that carry sensitive information around too.
