Claim 5:
6. A method for forming a sensor device, comprising:
forming a through opening in a carrier body;
forming an antenna in a manner surrounding the through opening on or in the carrier body;
arranging a fingerprint sensor in the through opening;
coupling the fingerprint sensor comprising a silicon-based area sensor to the antenna to inductively couple the fingerprint sensor to a booster antenna; and
forming an electrically conductive contact region on the carrier body adjacent to the through opening in such a way that after the fingerprint sensor has been arranged in the through opening, the contact region is arranged laterally adjacent to the sensor area and is configured to be touched upon the contact region being touched by a finger in order to bring the finger to a predetermined potential.
