Here in Denmark we also have a driver's license app. The app has a feature through which the user can identify themself to another party using the same app on their phone.

When used to identify, the app displays a series of QR codes which can be recorded by the 2nd phone through the camera. No need to hand over th e phone. It tranfers identifying information such as name, age and the photo so that the 2nd party can use it to validate on their screen.
