The present invention concerns a method of determining the living character of an element carrying a fingerprint, consisting of making impedance measurements at various points on the said element by means of electrodes. The populated PWB is manufactured by fabricating a PWB with exposed copper pads, coating the copper pads with an organic solderability preservative, depositing a solder paste that includes lead-free solder on the OSP covered copper pads, placing components and heating the PWB above a liquidous temperature of the lead-free solder in an air atmosphere. The product to be tagged may be a first product, characterized by a first particular characteristic, and a second product is characterized by a second particular characteristic different from the first particular characteristic. This voltage is then inhibited from being provided to the device in response to a second action of the actuator, for example, upon solenoid retraction after engine cranking. The covering includes an outer skin made of textile material.
