The device has an acceleration sensor which is arranged to react to a preset threshold value of a measured acceleration and, when the threshold value is exceeded, to trigger at least one of the actions of data storage, modification of a counter or transmission of a data telegram by radio. The apparatus further comprises an energy converter for converting a primary energy into electrical energy for operating the apparatus or the acceleration sensor.
