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.

Claims

1. A communication mobile substrate, comprising:

a communication interface for communications between a first contactless smart card housed in the mobile communications substrate connected to a wireless communications network, and a contactless smart card reader, the interface comprising;

a first antenna located on the contactless smart card;

a second antenna integrated in the communication mobile substrate; and

a third antenna, integrated in the communication mobile substrate and separate from the second antenna, configured to communicate with the wireless communications network; and

a slot and a receptacle for the introduction of a second contactless smart card, said second contactless smart card being positioned in the electromagnetic field of the second antenna and being able to receive and to execute an application program involving a communication with the contactless smart card reader through the second antenna,

wherein the first antenna and the second antenna are inductively coupled such that the first contactless smart card can communicate directly with the contactless smart card reader via the second antenna without using the third antenna or the wireless telecommunication network.

2. The communication interface according to claim 1, wherein the first contactless smart card is a double communication interface SIM card, having, on the one hand, electric contacts connected to matching contacts located in the communication mobile substrate, and having, on the other hand, said first antenna able to communicate through an inductive coupling with said second antenna integral with the communication mobile substrate.

3. The communication interface according to claim 2, wherein said communication mobile substrate is a mobile telephone compatible with the GSM standard or an equivalent.

4. The communication interface according to claim 3, wherein the second antenna is positioned on the body of the mobile telephone so as to face the first antenna positioned on the SIM card.

5. The communication mobile substrate according to claim 1, wherein said application program is a program for the payment of a service or a benefit, so that the communication substrate is able to make both mobile telephone transactions, using the SIM card and the wireless telecommunication network, and payment transactions using the second contactless smart card and the external smart card reader.
