Abstract
A portable communication apparatus has a microphone (14) and a processing device (31) with an input (37) 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 (17; 52) in the portable communication apparatus generates a second electric signal from an optical or magnetic input signal. The processing device (31) is operatively coupled to the reading device (17; 52), so that the second electric signal from the reading device may be received at the input (37) of the processing device.
Claims8
