When using Verifiable Credentials, rendering methods can be used when the issuer has a specific way that they want to express a verifiable credential to an observer through a visual, auditory, or haptic mechanism. For example, an issuer of an employee badge credential might want to include rich imagery of their corporate logo and specific placement of employee information in specific areas of the badge. They might also want to provide an audio read out of the important aspects of the badge for individuals that have accessibility needs related to their eyesight.
We encourage contributions meeting the Contribution Guidelines. While we prefer the creation of issues and Pull Requests in the GitHub repository, discussions also occur on the public-credentials mailing list.
