Abstract: A mobile-based equipment service system includes a remote server, a mobile device, and at least one equipment controller. The mobile device includes a user interface, and is configured to send a user authentication message, initiated by a user via the user interface, to the remote server. The remote server is configured to verify the user via the user authentication message and once verified, send an encrypted blob to the mobile device in response to the user authentication message. At least one equipment controller is configured to receive and decrypt the encrypted blob from the mobile device.
