A method for configuring a mobile communication device to perform transactions using a second communication channel that is different from a first communication channel through which the mobile communication device sends voice data. The method includes attaching a secure element to the mobile communication device. The secure element includes a memory storing an application, a processor configured to execute the application stored in the memory; and a wireless transceiver configured to send transaction data associated with the executed application through the second communication channel to a terminal that is remote from the mobile communication device.
