1. A card, comprising:

  • a physical interface that interfaces the card with a mobile host device including a Graphical User Interface (GUI), wherein the card executes wireless financial transactions independent of the mobile host device;

    an antenna that wirelessly receives Radio Frequency (RF) signals from and transmits RF signals to retail terminals;

    secure memory that stores user credentials used to execute the financial transactions with the retail terminals;

    a user-interface module that presents and receives information through the GUI of the mobile host device;

    an antenna control module that selectively switches the antenna between an activate state and an inactive state in response to at least an event, requests from the mobile host device, a hardware identifier or a network identifier while the antenna is in the inactive state, and, in response to failing to validate the hardware identifier or the network identifier, maintains the antenna in the inactive state.
