Abstract
The present disclosure relates to an electronic device comprising: at least one universal integrated circuit card or at least one secure element and at least one power supply circuit for said card or secure element, said power supply circuit being connected to at least a first power supply voltage source of the electronic device and comprising a voltage detector adapted to determine whether said first voltage source provides a first power supply voltage different from a reference voltage; and at least one near field communication module adapted to enter an active mode whenever said voltage detector determines that said first supply voltage is different from the reference voltage.
