Abstract

L'invention concerne un procédé permettant de gérer le courant d'un transpondeur et comprenant une pluralité de circuits, notamment au moins un premier circuit ayant un premier mode activé nécessitant au moins un premier niveau de puissance, et un deuxième circuit ayant un deuxième mode activé nécessitant au moins un deuxième niveau de puissance qui est supérieur au premier niveau de puissance. Selon ce procédé: le premier circuit reçoit un signal d'un dispositif lecteur ; sur la base d'une information contenue dans le signal de lecteur, le premier circuit détermine si le signal de lecteur exige un circuit autre que le premier circuit pour être opérationnel et, si le signal de lecteur nécessite un circuit autre que le premier circuit pour être opérationnel, le premier circuit envoie un signal de relance et le signal de lecteur au deuxième circuit. Le signal de relance fait passer le deuxième circuit du mode désactivé au deuxième mode activé.
