Abstract: An arrangement has a device which has at least one individualizing feature, detecting unit for detecting the individualizing feature, and a data storage unit in which the individualizing feature is stored and uniquely assigned to the device. The arrangement can reliably ascertain the authenticity of a product. The individualizing feature can be detected by the detecting unit and compared to the stored individualizing feature, which has already been stored in the data storage unit.
