Smart card with microphone

摘要

In order to allow for a secure capturing of audio signals, in particular a voice signal, the invention suggests a smart card (101) comprising a microphone (109) for capturing an audio signal and comprising at least one processing means (104; 110; 111 i) for processing the audio signal. By integrating the microphone into the smart card (101) security risks that occur in connection with external, peripheral microphones can be avoided. The smart card (101) may particularly be configured for use in a mobile communication device and the invention further suggests a mobile communication device comprising the smart card (101)
