Abstract: The invention relates to a method of switching communication channels enabling a card reader to communicate with several card circuits, each circuit having a communication channel. The reader applies a power supply voltage to the card by electrical contacts arranged on a connection button. The reader transmits a control signal for controlling the switching of the communication channel to an electrical contact located in the inserted part of the card but not on the button. Finally, the reader sets up activation signals for at least one circuit to enable said circuit to communicate via the connection button. The invention also relates to a removable device and a receiver for reading said device.

Abstract: The present invention relates to a method for downloading a binary configuration file in a programmable circuit implemented in a device. The device comprises at least one central processing unit, a plurality of connectors, and a programmable circuit enabling all or a part of the signals received by said connectors to be processed and transmitted to at least one other circuit of the device. The device analyzes the signals present on the connectors in order to define what other devices are connected and whether the connections are operational. Then, a configuration file is selected from among a set of configuration files according to the operational connections and is downloaded from a memory of the device into the programmable circuit. The invention also relates to a device having a component programmed according to the method previously described.

Abstract: An electronic card is disclosed including circuits of the protected zone include at least one control circuit. The electronic card further includes another zone defining a non-protected environment; the circuits of this zone do not need to comply with the distance constraint. The communication between the circuits of the protected zone and the non-protected environment is carried out by a communication circuit allowing or not allowing the electrical signals to pass. The passage of the electrical signals in the communication circuit is conditioned by an electrical control signal sent by the control circuit. Also disclosed is a method allowing the control circuit to be blocked if the electrical status of the signal controlling the passage of the signals does not correspond to the status imposed by the control circuit.

Abstract: To prevent being able to capture sensitive signals between electronic circuits placed on an electronic card, these circuits are arranged in a protected zone in such a manner so as not be distant from each other by more than a determined distance. The circuits of the protected zone comprise at least one control circuit. The electronic card further comprises another zone defining a non-protected environment; the circuits of this zone do not need to comply with the distance constraint. The communication between the circuits of the protected zone and the non-protected environment is carried out by means of a communication circuit allowing or not allowing the electrical signals to pass. The passage of the electrical signals in the communication circuit is conditioned by an electrical control signal sent by the control circuit.
