Abstract

The invention relates to a method of communicating a message relating to a transaction of a contactless application effected between a mobile terminal equipped with a contactless module and equipment, comprising the steps of detecting the end of the transaction between the terminal and the equipment, obtaining a message containing at least information identifying said application and end of transaction information, and communicating said message.
The invention also relates to a method of transmitting such a message including the steps of receiving end detection information, identifying the application associated with the transaction, and determining and transmitting the message to the mobile terminal.
The invention further relates to a mobile terminal and a secure module capable of being used with a mobile terminal.

First claim

We claim:

1. A method of communicating a message concerning a transaction of a contactless application effected between an equipment and a mobile terminal the mobile terminal comprising a processing unit, a contactless module, a secure module, and a man-machine interface, said method comprising the following steps:
the mobile terminal entering a magnetic field emitted by the equipment;
the contactless module receiving, from the equipment, a selection message containing an identifier of the contactless application;
the contactless module forwarding the selection message to the secure module;
the secure module launching the contactless application;
the contactless module detecting the end of a transaction between the mobile terminal and the equipment;
upon detecting the end of the transaction, the contactless module sending end of transaction detection information to the processing unit;
upon reception of the end of transaction detection information, the processing unit sending execution information to the secure module, said execution information enabling execution of a program on the secure module, said program being specific to said contactless application;
upon reception of the execution information, the secure module
executing said program to insert information identifying said contactless application and end of transaction information into a message;
transmitting said message and a man-machine interface command to the processing unit; and

the processing unit communicating said message on the man-machine interface in accordance with the man-machine interface command.

2. A method according to claim 1 , wherein the end of transaction detection information contains an identifier corresponding to said contactless application associated with the transaction.

3. A method according to claim 1 , in which the secure module is a subscriber card inserted in said terminal.

4. A method according to claim 1 , wherein the end of transaction information includes data of the contactless application updated after execution of the transaction.

5. A method according to claim 1 , wherein the communicating step comprises displaying said message on a screen of the mobile terminal and/or a step of reproducing a voice message containing said message by a loudspeaker of the mobile terminal.

6. A method according to claim 1 , wherein the information identifying said contactless application comprises an identifier stored during said transaction.

7. A mobile terminal including a processing unit, a contactless communications module, a secure module, and a man-machine interface,
the mobile terminal configured to:
enter a magnetic field emitted by an equipment;

the contactless communications module configured to
receive a selection message containing an identifier of a contactless application from the equipment;
forward the message to the secure module;
detect the end of a transaction;
upon detecting the end of a transaction between the terminal and the equipment, send end of transaction detection information to the processing unit;

the processing unit configured to, upon reception of the end of transaction detection information, send execution information to the secure-module, said execution information enabling execution of a program on the secure module, said program being specific to said contactless application;
the secure module configured to, upon reception of the execution information,
execute said program to insert information identifying said contactless application and end of transaction information into a message;
transmit said message and a man-machine interface command to the processing unit; and

the processing unit further configured to communicate said message on the man-machine interface in accordance with the man-machine interface command.

8. A mobile terminal according to claim 7 , wherein the secure module or the contactless communication module is further configured to store the identifier corresponding to said contactless application associated with the transaction during the transaction.

9. A system comprising a mobile terminal including a processing unit, a contactless communications module, a secure module, and a man-machine interface, the mobile terminal configured to:
enter a magnetic field emitted by an equipment;
the contactless module being configured to:
receive a selection message containing an identifier of a contactless application from the equipment;
forward the selection message to the secure module;
upon detecting the end of a transaction between the terminal and the equipment, send end of transaction detection information to the processing unit;

the processing unit being configured to, upon reception of the end of transaction detection information, send execution information to the secure-module, said execution information enabling execution of a program on the secure module, said program being specific to said contactless application;
the secure module being configured to:
upon reception of the selection message, launch said contactless application;
upon reception of the end of transaction detection information, identify the contactless application associated with the transaction;
execute said program specific to said contactless application;
determine by said program a message containing information identifying said application and end of transaction information; and
transmit said message and a man-machine interface command to the processing unit,

said secure module being inserted in said terminal,
the processing unit being further configured to communicate said message on the man-machine interface in accordance with the man-machine interface command.

10. A non-transitory computer readable medium having stored thereon instructions for executing the steps of the method according to claim 1 .

11. A method according to claim 1 , wherein the contactless application is a slave application controlled by the equipment.

12. A method according to claim 1 , wherein the contactless module is a contactless communication module and wherein detecting the end of a transaction comprises the contactless communication module receiving an end of transaction message from the equipment.
