Abstract

A method of exchanging data between a first electronic entity and a second electronic entity includes the following steps:

• • initiating (E400) communication between the first electronic entity and the second electronic entity subsequently to bringing the first and second electronic entities closer together;
  • in consequence of the initiation, transmitting (E415) an application from the second electronic entity to the first electronic entity;
  • storing (E416) the application in the first electronic entity.

Claims

1. Method of exchanging data between a first electronic entity (10) and a second electronic entity (30), characterized by the following steps:

initiating communication between the first electronic entity (10) and the second electronic entity (30) subsequently to bringing the first and second electronic entities (10, 30) closer together;

in consequence of said initiation, transmitting (E224;

E415) an application from the second electronic entity (30) to the first electronic entity (10);

storing (E234;

E416) said application in the first electronic entity (10).

2. Method according to claim 1 of exchanging data, wherein said step of initiating communication comprises the following steps:

remote power feeding of the first electronic entity (10) by the second electronic entity (30);

sending a communication set-up message from the first electronic entity (10) to the second electronic entity (30).

3. Method according to claim 1 of exchanging data, including a step, executed in consequence of the initiation and prior to the transmission of the application, of verifying (E208;

E406) the presence of said application in a memory of the first electronic entity.

4. Method according to claim 3 of exchanging data, wherein the verification step comprises the following steps:

the second electronic entity (30) sending (E206) the first electronic entity (10) a command designating said application;

searching (E208) a memory of the first electronic entity for said application.

5. Method according to claim 3 of exchanging data, wherein said verification step comprises the following steps:

the first electronic entity (10) sending (E402) a list of applications present in a memory of the first electronic entity;

the second electronic entity (30) determining (E406) the presence of said application in said list.

6. Method according to claim 1 of exchanging data, comprising the following steps executed in consequence of the initiation and prior to the transmission of the application:

displaying on the first electronic entity information indicating transmission;

awaiting validation (E410);

transmitting (E415) the application in the case of validation.

7. Method according to claim 1 of exchanging data, comprising a step of the first electronic entity preparing a request for loading of said application.

8. Method according to claim 7 of exchanging data, wherein the execution of the preparation step is conditional on receiving authorization of a user.

9. Method according to claim 1 of exchanging data, comprising the following steps:

the first electronic entity (10) executing (E236;

E420) the application in order to determine a response;

the first electronic entity (10) sending (E238;

E422) the response to the second electronic entity (30).

10. Method according to claim 9 of exchanging data, wherein the transmission (E224;

E415) of the application and the sending (E238;

E422) of the response are effected by communication between short range communication means respectively equipping the first and second electronic entities.

11. Method according to claim 1 of exchanging data, wherein the transmission (E224;

E415) of the application is effected by communication between high throughput wireless interfaces respectively equipping the first and second electronic entities.

12. Method according to claim 1 of exchanging data, wherein the application relates to the second electronic entity.

13. Method according to claim 1 of exchanging data, wherein the first electronic entity is a portable electronic entity.

14. Method according to claim 1 of exchanging data, wherein communication is short range wireless communication.

15. Method according to claim 2 of exchanging data, wherein said step of initiating communication comprises the following steps:

remote power feeding of the first electronic entity (10) by the second electronic entity (30);

sending a communication set-up message from the first electronic entity (10) to the second electronic entity (30).

16. Method according to claim 15 of exchanging data, wherein said verification step comprises the following steps:

the first electronic entity (10) sending (E402) a list of applications present in a memory of the first electronic entity;

the second electronic entity (30) determining (E406) the presence of said application in said list.
