A device for detecting the movement of part of a user's body and/or the approach of a portable user device. The device placed on board a motor vehicle. The device includes: a near field communication antenna having a resonance frequency between 3 and 30 MHz, including at least one continuous winding in the form of at least two sets of strips, each having different variable capacitance and different sensitivity, connected in parallel with the antenna. The antenna generating a different variation of impedance on the approach of part of a user's body towards the first or second set; a device measures a variation of impedance of the antenna. The device has a high series resonance frequency and detects the approach of a portable user device or movement of the body part taking place consecutively in front of the first and then in front of the second set of strips.
