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 () 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.
