Abstract: The invention is aimed at optimizing 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.

Abstract: A pairing device for establishing a secure wireless communication path between a first device having a first body-coupling communication interface and a second device having a screen.

Abstract: 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.

Abstract: The present invention relates to a communication object comprising means for radiofrequency communication with a remote device, wherein said communication means are capable of establishing a first short-range communication and a second communication having a longer range than the first communication, said long range being enabled by Bluetooth or Wifi technology. The communication means use the same type of communication technology for the first and second communications. The invention also relates to a method for implementing the dual-range radiofrequency communication of the object.
