Abstract: A system including: a self-contained unit including a first data carrier having an electronic identification device that is readable by radio frequency and the reading of which activates an electronic data sheet in a first database; and a third data carrier including a second identification code readable by an optical reader. A method is also described which uses the reading of the third data carrier to activate an electronic data sheet in a second database, and to allow the associative data between both identification codes to be visualized.
