Revoke by issuer

In this phase, the Issuer revokes the VDC after it has been issued to a user. This will remove the local VDCs from all devices. The user will no longer have the option to add the VDC to another device (including the same one) in the future.

Note: This scenario is different from a user deleting the VDC from their device. When a user deletes the VDC from their Google Wallet app, it is removed from that device only. The VDC remains active with the Issuer and can be added to another dvice (including the same one) in the future.
