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 () has a battery (), a radiofrequency circuit () allowing the mobile device () to exchange information with a host device (). The mobile device () comprises an electronic switch () connected between the battery () and at least the radiofrequency circuit (), where the switch makes it possible to supply power or not to the radiofrequency circuit. A power control circuit () is capable of controlling the electronic switch () so that it ceases to power the radiofrequency circuit as soon a break in communication is detected.

Mobile device with independent battery and radiofrequency communication interface

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. The pairing device includes a screen communication interface having a light sensor, which, in conjunction with the screen of the second device, allows definition of a light-based communication path for the transmission of a first pairing information from the second device to the pairing device, a calculator for generating a second pairing information once the first pairing information has been received by the pairing device, a second body-coupling communication interface, which in conjunction with the first body-coupling communication interface allows the definition of a body-coupling communication path for the transmission of the second pairing information from the pairing device to the first device, the second pairing information allowing the establishment of a secure wireless communication path between the first device and the second device.

Pairing device

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

Smartcard receiving device for providing a remote communication with switching means

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.
