RADIOFREQUENCY LOCAL COMMUNICATION INTERFACE BETWEEN A MOBILE PHONE AND A CONTACTLESS READER
First Claim
1. A communication interface between a contactless smart card integrated in a communication mobile substrate connected to a wireless communication network, and a contactless smart card reader located in the vicinity of the communication mobile substrate and intended to communicate by radio frequency with said contactless smart card, comprising, on the one hand, a first antenna positioned on the contactless smart card integrated in a communication mobile substrate, and, on the other hand a second antenna integral with the communication mobile substrate and connected through an inductive coupling to said first antenna so that said contactless smart card can communicate directly by radio frequency with the contactless smart card reader without using the wireless telecommunication network.

Abstract
A contactless smart card imbedded in a communication mobile substrate connected to a wireless communication network, and a contactless smart card reader in the vicinity of the communication mobile substrate for radiofrequency communication with the contactless smart card, are disclosed. On one hand, a first antenna is provided on the contactless smart card imbedded in the communication mobile substrate and, on the other hand, a second antenna is attached to the communication mobile substrate and connected by inductive coupling to the first antenna, so that the contactless smart card can directly communicate by radiofrequency with the contactless smart card reader without using the wireless communication network.
