The user on their smartphone travels in the real-world or the digital-world from place to place and easily access the locations or resources that they need in their day to day activities.
Secondary Use Case

Acceptance Criteria | ||
Given | The user has a modern smartphone that comes with, or has installed, a wallet application that holds modern mobile credentials. | Laptops also will work, but the smartphone limitations are more germane to this use case. |
When | I start any task that requires identity credentials. | or when I start planning for future needs. |
Then | I consider the credentials I might need to complete my task. This is typically on a website that tells me how access is granted. | The user should not need much special knowledge to complete this step. |
As Needed | I migrate to an issuer web site using either the browser or the wallet, as appropriate to acquire new credentials. | |
Fall back | I can scan some credentials from hard copy for entry into the secure store along with the fully digital credentials. See video for example. |
