Abstract
The present invention relates to a combined fingerprint sensing and body area network communication system for communication with an electronic unit using the body of a user as communication medium, comprising: a sensing arrangement and a body area network communication circuitry. The system is controllable between: a fingerprint sensing state, in which a first signal corresponding to the finger potential is provided to a connection electrode and a readout circuitry is controlled to provide sensing signals indicative of the capacitive coupling between each sensing structure and the user's finger; and a body area network communication state in which a second signal is provided to the connection electrode by a first of the electronic unit and the body area network communication circuitry to the other one of the electronic unit and the body area network communication circuitry.
