<p>An illegal ride such as fare cheating is prevented by using a ticket with hardly erasable visible information and a rewrite processor for recording the state of use of the ticket as visible information on the ticket. The ticket includes a substrate and a rewrite display portion using a reversible display element disposed on one of the surfaces of the substrate, made of a liquid crystal/polymer composite film (PDLC film) and requiring both heat and electric field for rewriting, and an information recording portion disposed on the other surface of the substrate and made of a magnetic recording layer. The date and time of use, etc., are recorded on the rewrite display portion and the information recording portion. The rewrite processor includes means for applying the electric field to the rewrite display portion by a charger or an electrode, and means for applying heat by a thermal head. <IMAGE></p> |
