National IDs run by governments are problematic for a variety of reasons. It would make more sense for one or more global nonprofit(s) with significant privacy, InfoSec and document security talent to offer an opt-in, open-source, voluntary "card" which can be deployed, maintained and improved to verify, nonrepudiate and generate a physical/electronic card for a given individual. This way, corporate interests and govt waste/incompetence can be mostly mitigated. Also useful would be the ability to grant/revoke rights to personal information in a single place and to load authoritative information onto a "card" (nationality, status, health records, etc.), perhaps backed by blockchain technology. Card being a physical token into an API that a consumer must have authorization and authentication to access.
