Description

A contactlessly rechargeable identification device is provided. The identification device can be power charged by a separate charging device using electromagnetic induction. The identification device includes an induction element to receive electromagnetic signal that is used to generate inducted electricity, a current and voltage partition circuit, and a power source to store the inducted electricity that is used to power the identification device.

L'invention concerne un dispositif d'authentification de charge sans contact et son procédé. Le dispositif d'authentification inclut : une alimentation électrique pour recevoir et transmettre le courant ; une unité de commande pour contrôler un signal ; un circuit de dérivation et diviseur de tension se connectant à ladite alimentation électrique et à ladite unité de commande pour contrôler la transmission de courant ; et un élément à induction électromagnétique se connectant au dit circuit de courant de dérivation et diviseur de tension pour induire et transmettre un signal électromagnétique qui a une certaine fréquence d'inductance électromagnétique. Alors que se produit l'induction électromagnétique sans contact entre le dispositif d'authentification et le dispositif de charge, ledit dispositif de charge commence à charger ledit dispositif d'authentification.
