ABSTRACT:
A portable communication apparatus has a microphone and a processing device with an input operatively coupled to the microphone. The processing device generates a digital output signal from a first electric signal received from the microphone. A reading device in the portable communication apparatus generates a second electric signal from an optical or magnetic input signal. The processing device is operatively coupled to the reading device, so that the second electric signal from the reading device may be received at the input of the processing device.
