I think Bejan briefly mentioned something similar along these lines in a recent podcast. It’s a very raw idea, but I thought it might open some discussion around potential real world use cases.
How about a Snapp that links to a verifiable ID so that you don’t have to show any personal info in order to get into a club / purchase alcohol etc? Instead you just show a QR code on your phone to prove you are over 18 / 21 etc
Obviously it needs to link to a particular person or you could just use someone else’s phone, so one solution could be to have to link with the touch ID / fingerprint scanner in order to open the snapp?
Im not sure about the USA, but I know a lot of places now have bar code scanners for covid green passes in Europe.
Would be interested to hear any thoughts.
