  • Patent number: 8369894
    Abstract: A system is provided for confirming certification of combinations of secure elements and mobile devices. The system includes secure element data and a secure element component on a removable secure element. The secure element component detects insertion of the removable secure element in a mobile device, retrieves the secure element data, and retrieves mobile device data from the mobile device. The secure element component determines whether a combination of the removable secure element and the mobile device is certified based on a comparison of the secure element data and the mobile device data. The secure element component provides a certification alert via a user interface on the mobile device in response to a determination that the combination of the removable secure element and the mobile device is not certified.

  • Patent number: 8181867
    Abstract: A system is provided for transit card credit authorization. An authorization component on a mobile device determines whether a balance on a transit card application on the mobile device is below a threshold, and determines whether a communication signal is too weak to request an approval for a balance increase from a server in response to a determination that the balance on the transit card application is below the threshold. The authorization component also determines whether credit data on the mobile device authorizes increasing the balance in response to a determination that the communication signal is too weak to request the approval for the balance increase from the server, and authorizes increasing the balance in response to a determination that the credit data authorizes increasing the balance. A fare gate enables access for the mobile device at the fare gate in response to the authorization component authorizing increasing the balance.
