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 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.

2. A communication interface according to claim 1, wherein the 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, an antenna able to communicate through an inductive coupling with said second antenna integral with the communication mobile substrate.

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

4. A 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. A communication mobile substrate, comprising a communication interface according to claim 1.

6. A communication mobile substrate according to claim 5, further including 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 programme involving a communication with the contactless reader through the second antenna.

7. A communication mobile substrate according to claim 6, wherein said application programme is a programme 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 mobile telecommunication network, and payment transactions using the second contactless smart card and the external smart card reader.

10. A communication mobile substrate, comprising a communication interface according to claim 2.

11. A communication mobile substrate, comprising a communication interface according to claim 3.

12. A communication mobile substrate, comprising a communication interface according to claim 4.

8. A communication mobile substrate, configured for receiving a double communication interface smart card having, on the one hand, electric contacts connected to matching contacts located in the communication mobile substrate, and having, on the other hand, an antenna able to communicate through an inductive coupling with a second antenna integral with the communication mobile substrate.

9. A communication mobile substrate according to claim 8, wherein the double communication interface smart card includes a mass storage available to the user so as to store data relating to the applications thereof.
