Abstract

Carte mobile à radiofréquences et procédé pour en contrôler les données. La carte mobile à radiofréquences comporte un module RFID/NFC standard (210), un module Bluetooth (220), une bobine supplémentaire (230) et un module (240) d'alimentation. Le module RFID/NFC standard (210) comporte une bobine standard (2101) et une puce RFID/NFC (2102). La bobine supplémentaire (230) est placée en-deçà d'une portée prédéfinie au voisinage de la bobine standard (2101). Le module Bluetooth (220) est relié à la bobine supplémentaire (230) via des broches, afin que, lorsque le module Bluetooth (220) reçoit un signal émis par un dispositif de commande Bluetooth, le signal reçu soit délivré à la bobine supplémentaire (230) via les broches d'entrée, de telle sorte que la bobine supplémentaire (230) émette des ondes électromagnétiques et se couple à la bobine standard (2101). La bobine standard (2101) distribue un signal respectif à la puce RFID/NFC (2102) en vue d'un traitement via les ondes électromagnétiques. Lorsque la puce RFID/NFC (2102) doit émettre un signal, la bobine standard (2101) génère des ondes électromagnétiques et se couple à la bobine supplémentaire (230), et la bobine supplémentaire (230) envoie un signal transporté par les ondes électromagnétiques au module Bluetooth (220) via les broches. La carte mobile à radiofréquences possède un champ d'application plus étendu et peut être utilisée de façon plus souple.
