This is the working area for the specifications of the OpenID Foundation's Digital Credentials Harmonized Presentation (DCHP) Working Group.

The DCHP Working Group supports a joint initiative between experts of ISO/IEC JTC 1/SC 17 (WG10) and the OpenID Foundation's Digital Credentials Protocols (DCP) Working Group to harmonize their credential presentation protocols.

ISO/IEC 18013-5 (Device Request / Device Response) and OpenID for Verifiable Presentations (Authorization Request / Authorization Response) take different approaches to credential presentation. The working group is developing a technical specification for a harmonized digital credentials request protocol that brings these together, supporting both in-person and online presentation and the coexistence of multiple credential formats, including ISO mdoc and IETF SD-JWT VC.

See the working group home page for more information.
