Park from Device

User initiates parking of his transit card from his device.

This section provides an overview of the workflow, including detailed steps, sequence diagrams, and potential error scenarios.

Workflow

Below are the high level steps of the suspension workflow:

1. Card Removal: The user selects the card to be deleted.

2. Unlink result: Since it's triggered from device, it is guaranteed that the digital card instance is removed from the device.

Sequence Diagram

The user initiates the park workflow from his wallet. Google will attempt to delete the token on the device. Additionally, Google notifies D1 Transit platform of the deletion by sending a deleteToken request.

D1 Transit then notifies the Transit Issuer so it can mark the card as parked and not to be used for transit.

The user may restore his card on same or different device, as long as he's connected with same Google account.
