Abstract
The present description relates to a mobile device comprising a near-field communication router and an antenna, coupled to the router via at least one impedance matching circuit between at least two impedance values. A first impedance value is selected to communicate with a near-field communication device of a first type in the presence of a near-field communication device of a second type, and a second impedance value is selected to communicate with a near-field communication device of the first type in the absence of a near-field communication device of the second type. The presence or the absence of a near-field communication device of the second type is determined based on polling frames transmitted by the antenna.
