Abstract

Charge NFC La présente description concerne un procédé pour aligner un smartphone (1) fournissant de l'énergie sans fil NFC pour charger une batterie (208) d'un dispositif (2), le procédé comprenant : l'émission, avec une première antenne NFC (102) du smartphone (1), d'un champ NFC pour charger sans fil la batterie (208) du dispositif (2) comprenant une deuxième antenne NFC (202) ; l'obtention, avec le smartphone (1), d'une valeur mesurée d'un signal représentatif de la puissance du champ NFC entre le smartphone (1) et le dispositif (2) ; la détermination, par le smartphone (1), d'une plage de valeurs parmi une pluralité de plages de valeurs à laquelle la valeur mesurée appartient ; et l'émission, par le smartphone (1), d'au moins un signal de notification à destination d'un/e utilisateur/trice avec une fréquence déterminée par la plage de valeurs déterminée.
