    a second wireless module for emitting the radio identification signal and for receiving the radio user signal;

    a power supply for supplying power to the processing module while receiving a power control signal; and

    a control module electrically connected to the power supply;

    wherein before the power supply supplies power to the processing module, the control module is capable of checking whether the identification code within the radio user signal matches a predetermined identification code as the second wireless module receives the user signal;

    if the identification code within the radio user signal matches the predetermined identification code, the control module is capable of transmitting the power control signal to the power supply.
