<p>The portable electronic device (10) comprises an electronic circuit capable of storing data therein, capable of processing data, and capable of data input and output; a control device (12) operatively linked to the electronic circuit (14), with an invariable activation command being issued when the control device is triggered; first and second data conveyance functions programmed in the electronic circuit; a cue receiver (18) for receiving a selectively emitted activation cue from a source (9) external to the portable electronic device; and a power connector or an internal power source (20) for providing power to the portable electronic device. In use, upon the control device being selectively triggered to issue the invariable activation command, the electronic circuit will accomplish the first data conveyance function if an activation cue was received by the cue receiver and the second data conveyance function if no cue was received by the cue receiver.</p> |
