8. The portable device according to claim 1 , wherein the electronic display is bistable.

9. The portable device according to claim 8 , wherein the electronic display comprises electronic paper.

10. The portable device according to claim 1 , wherein the electronic display is a touch display.

11. The portable device according to claim 1 , wherein the electronic display includes layers with said layers including marked security elements.

12. The portable device according to claim 11 , wherein the security elements constitute visual elements complementary to electronically displayed graphical elements.

13. The portable device according to claim 11 , wherein the marked security elements are selected from a group consisting of logos, graphics, holograms and guilloches.

14. The portable device according to claim 1 , further comprising at least one of the following:

carrying out of secure electronic transactions in association with a driver connected to a host computer and connected to a communication network, with personal information or information relating to the transaction being securely entered on a touch screen of the portable device;

a physical access control implementing a double step of control including the user's authentication control by the portable device, by biometry, and a physical access control of access rights contained in the portable device;

authentication and visual monitoring of at least one person;

authentication logical access control for at least one user; and

displaying of the data other than the graphical data.

15. The portable device according to claim 14 , wherein, for the electronic transaction, information is transmitted directly on the communication network via a secure channel established between the portable device and a remote unit connected to the communication network.

16. The portable device according to claim 1 , wherein the display mode changing controls are user-provided.

17. A device including an interface connected to a display, wherein the display includes a portable device, comprising:

a processor;

graphical data visible from a face of the portable device,

an electronic display on which the graphical data can be presented, and a display microcontroller that controls the electronic display to operate in a first, priority mode in which the graphical data is presented including an identity document, and at least one other mode in which other data is presented on the electronic display,

wherein when the electronic display is not already operating in the first priority mode and upon detection of a predetermined condition, said predetermined condition being at least one of a battery charge state that is less than a predetermined level and a predetermined physical orientation of the portable device, the display microcontroller is configured to

(1) automatically switch the electronic display to operate in the first, priority mode in which the graphical data is presented, and

(2) maintain the electronic display to operate in the first, priority mode in which the graphical data is presented by rejecting display mode changing controls if the predetermined condition is still present.

18. The device according to claim 17 , wherein the display is removable with respect to the device and constitutes at least one of an additional display of the device and a unique display therefor.

19. A method of the graphical personalization of a portable device having an electronic display, said method including:

operating the electronic display in a first, priority mode in which graphical data is presented on the electronic display of the portable device;

operating the electronic display in at least one other mode in which data other than the graphical data is presented on the electronic display;

detecting a predetermined condition, said predetermined condition being at least one of a battery charge state that is less than a predetermined level and a predetermined physical orientation of the portable device; and

in response to detection of said predetermined condition, when the electronic display is not already operating in the first priority mode,
