Objective

Good Health Pass compliant implementations must offer a paper based alternative, based on standard QR code formats and interoperable with their digital counterparts.

Terms of Reference

An all-digital solution to health passes is simply not an option when it comes to combating a public health crisis. Simple, easy-to-use paper credentials must be an option so those in low-resource settings or those who do not own – or wish to use – a mobile phone are not excluded.

...

Many of the challenges described in this paper apply equally to both paper and digital credentials. Thus, the primary goal of this Good Health Pass Collaborative workstream is to enable implementations to produce paper credentials that are interoperable with – and contain as many benefits of – their digital counterparts as possible.

Responsibilities and Deliverables

Key Interoperability Questions (from GHPC Interoperability Blueprint Outline V2)

  1. Which paper credential format or formats will digital health pass systems support?
  2. Will paper credentials be compliant with the W3C Verifiable Credentials Data Model 1.0 specification?
  3. Will paper credentials require a digital signature to be included? Which signature formats will Good Health Pass systems support?
  4. Should the same privacy policies be applied to paper credentials, such as data minimization and disclosure limited to what is strictly required?
  5. How will these digital QR codes relate to the QR codes for paper credentials?
  6. Is there a need to turn a paper credential into a digital credential, and vice versa?
  7. What considerations need to be made for smart cards?
  8. How will interoperability between these choices be tested/verified/certified?
