Re: Electronic Driving Licenses

Hi Oliver

Yes I think we should try to influence the standard if possible. They
are clearly influenced by other standards otherwise they would not be
looking into OIDC and CBOR. Since we believe VCs are superior and
designed for driving licenses then we should try to sell VCs to them.

Kind regards

David

The exchange protocol they were looking into was OpenID Connect. In theory, the “token” could also be a DID, but the exchange format would need to be extended respectively ISO 18013-5 amended.
