Title (EN) CONTACTLESS CHIP CARD ASSOCIATED WITH RF TRANSMISSION MEANS
(FR) CARTE A PUCE SANS CONTACT ASSOCIEE A DES MOYENS DE TRANSMISSION RF
Abstract:
(EN) The invention concerns a chip card associated with RF transmission means. Said chip card comprises on each surface high permeability zones arranged so as to concentrate the flux generated by the RF transmission means onto a sensor coil. To ensure the proper functioning of the system, the transmission means generate flux lines parallel to the surface of the chip card.
(FR) La présent invention concerne une carte à puce associée à des moyens de transmission RF. Cette carte à puce comporte sur chaque face des zones à perméabilité magnétique élevée disposées de manière à concentrer le flux généré par les moyens de transmission RF sur une bobine captrice. Pour que ce système fonctionne correctement, ces moyens de transmission RF doivent générer des lignes de flux parallèles à la surface de la carte à puce.
