What if it was the size of a credit card and it had stuff like your name, date of birth and even a picture of your face. I want to name this invention an ID card…

And if you added a cryptographic layer to it, with your own private key baked into it, you could both sign the documents, confirm your identity and the government could confirm it's actually you....

....wow, that would be reinventing the existing model of the leading ID cards....

Crazy if you think about it :)
