Abstract: A mobile apparatus includes a cellular telephone and a subscriber identification module (“SIM”). SIMs include an interpreter written in a computer language. A game program, which is written in the same computer language, is loaded into the memory of the SIM and is interpreted by the SIM's interpreter. The game program is then executed by the cellular telephone so that the game can be played.

Abstract: An integrated circuit card comprising a card body, an integrated circuit fixed in a cavity of the card body, an antenna extending over a face of the card body and connected to the integrated circuit, and a layer of resin covering the integrated circuit and at least a portion of the card body immediately adjacent to the integrated circuit.

Abstract: For a memory card that includes memory blocks containing reliability parameters (P.sub.1, P.sub.2, and P.sub.3) and respective reliability weights (PF.sub.1, PF.sub.2, and PF.sub.3), for the parameters, the method comprises the following steps:determining the reliability weights corresponding to the access request;computing an interactive reliability weight (PFI) as a function of the respective reliability weights of the access request;comparing the interactive reliability weight with an access reliability index (FA); andauthorizing or refusing access to the application as a function of the results of the comparison.

Abstract: The chip of an invention for an electronic circuit card comprises a semiconductor microplate having an active face provided with contact pads and on which projections are formed of different heights. The active face of the microplate is coated, at least in part, in a layer of insulating material having a thickness that is greater than or equal to the height of the highest projection, said layer being shaped so as to give free access to the contact pads and having an outer face parallel to the periphery of the active face of the microplate. The layer enables the chip to be implanted in a card body while remaining accurately parallel thereto, which is essential to enable conductive tracks to be made subsequently by silk-screen printing.

Abstract: The electronic card of the invention comprises inside a card body, a printed circuit including two spaced-apart electrodes on the bottom of a cavity formed in the card body and having two parallel side faces. A switch actuator is displaceable inside the cavity parallel to the side faces thereof between an active position in which it electrically interconnects the two electrodes and an inactive position in which it leaves the two electrodes electrically isolated from each other. The face of the switch actuator which faces the electrodes has a conductive coating thereon. Complementary stop means are provided by the cavity and the switch actuator.

Abstract: Process for protecting components of smart cards from fraudulent use, wherein the component is locked as long as an unlock order formed by a secret key has not been applied thereto, characterized in that it consists in writing in the component, at the time of its manufacture, a value and a result, the result being associated with the said value by a given algorithm and the secret key.

Abstract: A conductive ink for making a conductive wiring comprises first and second metal grains dispersed in an organic material. The second metal grains are interposed between the first metal grains and they have a melting temperature that lies between the melting temperature of the first metal grains and the setting temperature of the organic material.

Abstract: The contactless smart card according to the invention is provided with an electronic circuit which is physically inacessible from the outside and including, on an insulating film (12), electronic components connected by conductive elements (11). According to the invention, at least one of the components of the electronic circuit is formed by a module (1) including an insulating support (2) provided with holes (3, 4), a printed circuit (5, 6) located on one of the faces of the insulating support, an integrated circuit (7) located on the side of the other face of the insulating support and electrically connected to the printed circuit by lead wires (8) passing through holes in the insulating support, and a protective insulating material (9) encapsulating the integrated circuit (7) and the lead wires (8), the printed circuit of the module (1) being held by a conductive material (10) against the conductive elements (11) borne by the insulating film (12).

Abstract: Process and memory card (1) for making secure the writing of sensitive data into the EEPROM data storage memory (2) of the card, consisting, during each write, in performing the following operations in succession:a) registering the start address of the data area (Ze) of the card to which a write is to be performed, into an address field (Za) of the memory);b) reading the data present in this data area (Ze) of the memory;c) storing the read data in a save area (Zs) of the memory;d) writing the "WRITE IN PROGRESS" datum into a flag area (Zd) of the memory;e) performing the write to the data area (Ze) of the memory; andf) writing the "NO WRITE IN PROGRESS" datum into the flag area (Zd) of the memory.
