In Germany, everyone's national ID – which everyone has – has a NFC chip to securely identify you digitally. It was introduced 15 years ago and can be read by any smartphone. (It does use trusted third parties which only share the requested data though.)

You'd think that 80 million people from a rich first world country would be enough of a market to use this.

No, we're showing our faces and waving our IDs in front of the camera while an Indian half-asses the identity check like everyone else.
