1. A method of dynamically operating a radio frequency identification (RFID) tag device for conducting transactions, comprising:

  • powering the RFID tag device through an associated device interface of the RFID tag device;

    receiving, at the RFID tag device, from an associated device over the associated device interface, a dynamic identifier to be used in a transaction;

    receiving, subsequent to receiving the dynamic identifier, a read signal from a reader at an RFID interface; and

    responding to the read signal over the RFID interface by transmitting the dynamic identifier to the reader; and

    removing power from the associated device interface in response to responding to the read signal;

    wherein the dynamic identifier is only stored in the RFID tag device while power is provided to the RFID tag device via the associated device interface.
