Abstract
La présente invention concerne un lecteur (10) qui comprend un circuit de lecture (12) pour lire des informations en provenance d'un objet (14) qui peut être un transpondeur RFID. Plusieurs antennes remplaçables (16) sont prévues. Des moyens (20) sont fournis pour identifier un paramètre de l'antenne correspondante (16), tel qu'une fréquence de résonance, une capacité de puissance, etc. Des moyens de commande (22) commandent le circuit de lecture (12) en fonction du paramètre enregistré par les moyens d'identification (20) d'une antenne (16) montée sur le circuit (12).
