Abstract:
The invention relates to a method for manufacturing a smart card and a thus manufactured smart card. The invention applies more particularly to smart cards comprising an antenna. The problem to be solved by the invention is to provide a method for manufacturing a smart card comprising an inlet (30) which hosts an antenna (31) and an electronic module (40) electrically connected to said antenna, said inlet (30) being covered by at least one layer (39), said method being cheaper than existing methods, easier and shorter to execute, and well adapted to both groups of contactless smart cards, namely dual-interface cards and contactless or hybrid cards. The solution to this problem is achieved by the following steps : - affixing a wired antenna (31) onto the inlet, - affixing at least one metallic plate (33) onto both ends (32) of the wired antenna (31), - creating connection areas (35) in the metallic plate(s) (33), at each end (32) of the wired antenna, and - connecting the electronic module (40) to the thus obtained connection areas.
Abstract:

The method consists in associating with at least one data item stored in said means (7,11) at least one identification attribute used to classify said data item into a data family. This invention also concerns the electronic module in which said method is implemented and the card comprising said module.
Abstract:
The present invention consists in a method for managing threads in a device comprising data processing means (3), a non-volatile memory (7) and a volatile memory (11). The method consists in storing a thread dynamic execution context of a program, called the thread control block (TCB), in said non-volatile memory (7).
Abstract:
The invention concerns a method to manufacture a component, such as a silicon wafer-based microcontroller, integrated circuit or equivalent (1, 14, 20), applicable in particular to smart cards, characterised in that means (18) are planned to destroy or damage said component in the event of an attempt to thin the silicon wafer; in particular, sais means can act on the polarisation of said wafer; in particular, the silicon substrate wafer is polarised from the back side (17) only. The invention also concerns a component so manufactured and a smart card including such components.
Abstract:
Data which is stored on a smart card is sent to a device external to the smart card. The data is stored on the smart card in a field of entries, the field of entries on the smart card is indexed and a flag is associated with each field index, indicating whether the entry belonging to the index has changed or not. The external device has an indexed field of entries which matches the field of entries on the smart card. To the external device only those entries are sent, together with their index value, where the flag associated with the index indicates a change. The flags associated with the indices whose entries were sent to the smart card are cleared. The entries are received on the external device external to the smart card, together with their index values and each of the received entries is stored in the field on the external device at the position indicated by the index value received together with the entry.
Abstract:
A two-way communication device has a master transmitter (SysM1, TRM1, SysM2, TRM2) connected to at least one slave transmitter (SysS1, TRS1, SysS2, TRS2) by an active connection wire. The master transmitter and the slave transmitter have a common reference (GND). The master transmitter can transmit a master signal (S1) to the slave transmitter and the slave transmitter can transmit a slave signal (S2) to the master transmitter.The master signal (S1) is a digital modulation in voltage. The slave signal (S2) is a digital modulation in current.
Abstract:
A card body comprises a module-receiving part (3) having a cavity for receiving an electronic module ML. The card body comprises a first side part (4) coupled to the module-receiving part (3), the first side part being separated from the module-receiving part by a first separation line (6), and a second side part (5) coupled to the module-receiving part (3), the second side part being separated from the module-receiving part by a second separation line (7). The module-receiving part defines a third shape corresponding to a third card body (3) type when the first (4) and second (5) side parts are detached from the module-receiving part (3). The module-receiving part defines a second shape (2) corresponding to a second card body type when the first (4) and second (5) side parts are coupled to the module-receiving part (3).
Abstract:
