The three scenarios that are covered are:

Creating and receiving credentials
Learn how a company can customize the credentials they issue to their customers and the notifications that customers receive.
Presenting and verifying a user credential
Learn how a user can provide proof of credentials to a provider of service (in this case, proof of insurance to a car rental company) and how the provider of service can then verify the user's credentials.
Revoking a credential and notifying a user
Learn how credentials can be revoked from a user's digital wallet app and how users can be notified that the credential was revoked. This scenario also covers how a user's credentials can be reissued.
