(EN) The invention relates to a portable electronic device (SC, TK) comprising electric input means (VCC, GND, ANT) for receiving electric power from an external power supply. The portable electronic device (SC, TK) comprises an application, the application being set to be triggered when power is supplied to said electric input means (VCC, GND, ANT), and to not communicate with entities external to the portable electronic device (SC, TK), or to only notify such entities of an event. The application is further set to configure the portable electronic device (SC, TK), and to be successfully executable at most once. The invention also relate to a manufacturing equipment (M) for configuring a portable electronic device (SC, TK) and to a method for configuring a portable electronic device (SC, TK).
摘要:
The invention is a method of managing data in a portable electronic device comprising first and second controllers. The first controller comprises a first microprocessor and a first non volatile memory. The first microprocessor comprises a first piece of code. The second controller comprises a second microprocessor and a second non volatile memory. The second non volatile memory comprises a first executable data. The method comprises the following steps of: a) loading and activating the first piece of code in the first microprocessor, b) sending by the first controller a first request for retrieving the first executable data from the second non volatile memory, c) loading the first executable data into the first controller, and d) executing the first executable data by the first microprocessor.

The invention relates to a smartcard receiving device, comprising a contact interface (11) for communicating with the received smartcard (2); a remote communication interface (13) for communicating with a first remote device (3); a protocol bridge (12) designed to establish a transaction with the received smartcard (2) through the contact interface (11). The smartcard receiving device further comprises a communicating device detector (14, 15) adapted to detect a second remote device (5) communicating according to a remote communication protocol different from the communication protocol used by said remote communication interface (13). The protocol bridge (12) interrupts the transaction with the received smartcard (2) when the second remote device (5) communicating according to said different remote communication protocol is detected.

摘要:
The invention is aimed at optimising the life of the power supply of mobile equipment with a radiofrequency communication interface by switching off the power to it when it reaches a given state. A mobile device (102) has a battery (206), a radiofrequency circuit (201) allowing the mobile device (102) to exchange information with a host device (101). The mobile device (102) comprises an electronic switch (202) connected between the battery (206) and at least the radiofrequency circuit (201), where the switch makes it possible to supply power or not to the radiofrequency circuit. A power control circuit (203) is capable of controlling the electronic switch (202) so that it ceases to power the radiofrequency circuit as soon a break in communication is detected.
