For this purpose, the user must bring the ticket into a reader, which documents the devaluation, for example, by stamping the entry point and entry point. As a result, the user tariffs are granted the authorization for a specific route. In addition, by invalidating the card re-use is excluded. The user and also an inspector can visually recognize by the stamping that the card has already been used.

Abstract

L'invention concerne un dispositif transpondeur comportant un récepteur transpondeur pour recevoir sans contact un signal de transpondeur contenant une information et un dispositif d'affichage, qui adopte, en fonction des informations, un état sur les deux états différentiables visuellement. Des dispositifs transpondeurs connus de ce type présentent l'inconvénient d'être coûteux à produire. L'information perceptible optiquement par le biais de l'état différentiable visuellement est appropriée pour transmettre des informations à l'utilisateur, directement par voie optique, sans auxiliaires techniques. Ledit dispositif utilise avantageusement les procédés de production connus en technique d'impression et est de ce fait de production avantageuse. L'invention vise à améliorer la fiabilité, la protection contre les faux et l'aspect économiquement avantageux d'un dispositif transpondeur du type générique. A cet effet, il est prévu que le récepteur transpondeur présente un circuit de réception comportant au moins deux électrodes, qui déclenchent une réaction électrochimique, à réception du signal de transpondeur, ladite réaction induisant un échange entre les deux états différentiables visuellement.
