<p>Identification device with information medium and method for numerical coding of the information on such a medium. The medium is produced on a card comprising two distinct tracks (6, 7) comprising zones coded in the form of bars perpendicular to the direction of the tracks. Each of these tracks corresponds to one of the logic states, <<0>> or <<1>>, for the relevant item of information. A bar on one track (6) represents a <<1>> and a bar on the other track (7) represents a <<0>>. <IMAGE></p> |
