Compact Credentials

Compact Credentials are used to represent claims of data that can be cryptographically proven as authentic while being compact enough to fit inside a QR code. They are ideal where high information assurance is required but not high identity assurance about the entity presenting the credential.

The following sections will provide you with further information on Compact Credentials:

  • Core capabilities: Learn more about the core capabilities enabled when using the Compact Credential profile.
  • Credential profiles: Learn about the two different profiles (Compact and Compact Semantic Credentials) and how to choose the one most suitable for your use case.
  • Data structure: Learn more about how Compact and Compact Semantic Credentials are built, and how to use standard and custom claims.
  • Revocation: Learn more about the concepts and data structures which enable revoking Web Credentials in a privacy preserving manner.
  • DIDs: Learn more about Decentralized Identifiers (DIDs) that are used as digital identifiers for issuing, holding and verifying Compact Credentials.
  • Implementation considerations: Learn about key considerations that should be explored as part of implementing either a Compact or Compact Semantic Credential into your ecosystem.
  • Compact Credentials across MATTR Platforms: Introduces key capabilities that are available across MATTR platforms when you embed Compact Credentials into your ecosystem.

Compact Credentials can be converted to a number of formats. This includes PDF documents that can be presented digitally or printed, as well as Apple and Google passes that can be stored in a digital wallet. Thus, Compact Credential reduce the digital divide by supporting offline or paper-based contexts alongside digital-first channels.

Holders present Compact Credentials by showing a verifier a QR code representing their credential. This can be scanned visually, or digitally transmitted by uploading an image or PDF. Verification can be online via API or entirely offline. This makes Compact Credentials ideal for rapid verification scenarios and/or when there is no reliable internet connectivity.

Compact Credentials are bearer credentials, where all the assurance is fully self-contained within the QR code, with no need for complex dynamic presentation capability from the holder. However, this means that the verifier cannot verify the identity of the person holding and presenting the credential.

Discount vouchers, physical asset tags and luxury goods verification cards are all examples where having authentic information through the supply chain increases the value of goods and services produced, without relying on the identity of the holder.

Therefore, Compact Credentials are ideal where high information assurance is required but not high identity assurance about the entity presenting the credential.
