The portable electronic device includes an electronic circuit, a control device operatively linked to the electronic circuit, first and second data transceivers operatively linked to the electronic circuit, a cue receiver operatively linked to the electronic circuit, a data conveyance switching element operatively linked to the electronic circuit and capable of being in either one of a first and a second state, and power means for providing power to the portable electronic device. The method of data conveyance includes awaiting for an activation cue to be received at the cue receiver; if an activation cue is received at the cue receiver, assigning its first state to the switching element, while if no activation cue is received at the cue receiver, assigning its second state to the switching element; and selectively triggering the control device to issue an invariable activation command. Upon the control device being triggered, if the switching element is in its first state, first data will be forwarded to the first data transceiver for initiating a data exchange operation with a first external data exchange device; while if the switching element is in its second state, second data will be forwarded to the second data transceiver for initiating a data exchange operation with a second external data exchange device.
