Abstract

La présente invention concerne un procédé de commande de module de reconnaissance d'empreintes digitales, un terminal mobile et un support de stockage. Le procédé comprend les étapes suivantes : lorsqu'il est détecté qu'un utilisateur touche un module de reconnaissance d'empreinte digitale et qu'un mode de touche d'accueil échoue, détecter si un événement d'interférence électrostatique se produit (101) ; lorsque l'événement d'interférence électrostatique est détecté, commander le module de reconnaissance d'empreinte digitale de telle sorte que ce dernier réintroduit le mode de touche d'accueil, et initialise un état de détection capacitif du module de reconnaissance d'empreinte digitale (102) ; et lorsque l'événement d'interférence électrostatique n'est pas détecté, commander le module de reconnaissance d'empreinte digitale de telle sorte que celui-ci est commuté vers un mode d'acquisition d'empreinte digitale (103). Il est possible de faire revenir le module de reconnaissance d'empreintes digitales à l'état de fonctionnement normal lorsque le mode de touche d'accueil échoue.
