<p>#CMT# #/CMT# The interface has an offset or offsetting antenna (15) arranged at the exterior of a structure of a mobile communication medium e.g. mobile telephone (1), such that a contact/contact less smart card i.e. subscriber identity module (SIM) card (11) directly communicates with a contactless communication network passed by the medium. A flexible circuitry i.e. set of wires (13), electrically connects the smart card and terminals of the antenna. The antenna is coupled to the smart card, in an inductive manner. #CMT#USE : #/CMT# Radiofrequency communication interface for being arranged between a contact/contactless smart card i.e. subscriber identity module (SIM) card, that is connected to a smart card connector of a mobile communication medium (claimed) e.g. radiofrequency communication medium such as mobile telephone compatible with global system for mobile communication (GSM)network, and a contactless communication network. Can also be used for a secure digital card, a mini-secure digital card and a Multimedia card(RTM: flash memory card) of a personal digital assistant. #CMT#ADVANTAGE : #/CMT# The communication interface is simple and inexpensive and can be adapted to set of installed mobile telephones. The communication interface can be arranged on an outer surface of a cache of a battery of the telephone such that the antenna directly captures the magnetic flux from a contactless chip card reader without traversing a body of the telephone. The interface ensures simple connection between an application that is executed in a memory i.e. subscriber identity module card, placed under a cover formed by the battery and a contactless reader situated at the exterior of the telephone. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a plan view of a communication interface inserted in a mobile telephone. 1 : Mobile telephone 9 : Battery 11 : Subscriber identity module card 13 : Wires 15 : Offset or offsetting antenna.</p> |
