DigiLocker used to be very shitty. When I started using it (before I found Bitcoin), you could open the app to show your driver's license or Aadhar card etc to the cops, and they could verify the authenticity of it, but the app won't work most of the time, so even they would only accept a physical copy

Now with it's OAuth like flow, it's actually useful for sharing your KYC info with apps that support it, without revealing your actual documents. But now I have no use for it anymore
