Abstract

A device has a measuring device, in particular an alcohol-measuring device (3), for measuring the state of intoxication of a test subject and for generating a corresponding measured value. A camera (5) is provided for recording an image with the face of the test subject. A control unit (4) is configured to store the measured value together with the image in a memory unit (10). An analyzer (12) is configured such that the analyzer can identify a face and/or a defined, fixed pattern in the image. A follow-up action is triggered by the analyzer (12) when a face and/or pattern could not be identified.
