## Where their work shows up

Decentralized identity spent a decade as an argument between specifications. Issuing a real mobile driving licence for a state DMV is where that argument meets procurement, accessibility requirements, and a public that did not ask for a wallet, and where [ISO 18013-5](https://startwithidentity.com/standards/iso-18013-5-mdl/), [verifiable credentials](https://startwithidentity.com/standards/verifiable-credentials/), and [OpenID4VC](https://startwithidentity.com/standards/openid4vc/) have to work together in production.
