The user has performed some sort of biometric identification to the Device (such as a face or digit scan) that unlocks the devices device's ability to authenticate the user. The user taps the device on a verifier and is then asked if it is ok to release information the the Verifier as displayed on the Device's screen. The user makes some gesture that allows the requested data to be released to the Verifier. The user is admitted (or not) to the place that they are trying to enter.

- The User and Holder will typically be the same person and so the proof generated by the Device is typically just that the two are verified by the Device to be the same individual (i.e. that the person in possession of the Device (the User) is the known Holder of the Device.)
- Proof of presence and notarization provide the same sort of abstraction, some sort of legally mandated evidence that the real world person made an intentional act. As technology advances and deep fakes of all sort abound, this is never more that a best-effort attempt to satisfy others of our intention to act. It will never be possible to be any more than evidence that must be judged by some entity which is here called the Verifier.

- A user walks up to a venue that has a age limitation carrying their smartphone which contains all of their identity credentials.
- The venue has an automated access portal that is unmanned and has no line. There may be another access portal with a long line.
- The user opens their smart phone with a face scan and holds it up for validation.
- The phone displays the venue's identify information on the phones screen with the data that will be needed for them to access venue. (It may even contain a ticket that the user acquired online earlier.)

- The portal verifies the information and allows one individual to pass through.
